Handling This chapter is intended for you, the end user of the product, and describes how your new heating system functions and your options for adjusting the settings in order to make your house as comfortable as possible with the best cost‐efficiency. Ask your installer to go through the system with you, and ask for the registration form to fill in after the installation is completed. How the Exotic Compact works The Exotic Compact consists of 2 parts: a tank component and a heat pump component. The tank holds the water which is used to heat your house and to supply hot water for showering, etc. Since the water to heat your house (radiators/underfloor heating) does not need to be equally hot all the time, the tank is divided into two sections, a lower section and an upper section. There is a plate between these two sections, which ensures that the tank can maintain two different temperatures. Lower tank section The lower tank section is used primarily to heat the house, but also to preheat the cold water that will become hot water in the Exotic Compact. Depending on your heating system, different water temperatures are necessary at different outdoor temperatures. If it is warm outside, the system does not need very hot water. Conversely, if it is very cold outside, higher temperatures are needed to heat the inside of the house. The temperature of the water that is sent to your radiators / underfloor heating is determined by the so‐called heating curve. You can set this curve yourself. It is important to make sure that the heating curve is set properly ‐ for your own comfort, but also to ensure the overall efficiency of the heating system. Upper tank section The upper part of the tank is used primarily to heat your hot water. Because you always want to have hot water available, the heat pump keeps this section warm regardless of the outdoor temperature. You can set the temperature in this part of tank yourself. The higher the temperature, the warmer the hot water, but hotter water needs more energy and is therefore more expensive. Hot water Exotic Compact uses a special technique for heating the hot water through a special exchanger. ...
Heating curve This chapter describes how the heating for the house works and how you can adjust the so‐called heating curve to achieve maximum savings without sacrificing comfort. Heating requirements for the house How your house is built, the climate in your area, and what type of heating system you have all influence how much energy is needed to heat it. There are many factors that affect the temperature required for your heating system. For example, if it is cold outside, the house will need more energy/heating. If you have an old radiator system, the radiators will require warmer water than modern radiators to generate enough heat. If you have an underfloor heating system, the water will not need to be as hot to achieve sufficient heating. Based on all of these parameters, which vary from house to house, the settings will be unique in each case. We call this the heating curve. In simple terms, the heating curve can be described as the relationship between the outdoor temperature and the temperature (flow line) that your heating system requires ‐ see the diagram below. You can adjust the heating curve in many different ways so that it is suited precisely for your house, and we will review these in this chapter. Remember! A house heating curve that is set properly can save a lot of money over the year. Example of a heating curve. (This is the factory default heating curve) ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Outdoor temperatur ...
Setting the curve There are 3 basic settings for the heating curve, points A, B and C. With these 3 points, you can adjust the gradient and vertical position. The aim is always to set the curve as low as possible. Point A Point A describes the temperature of the water to be sent to the radiators if the outdoor temperature is ‐15°C. The factory default setting for this item is 55°C. In other words, when it is ‐15°C outside, the Exotic Compact unit sends 55°C water to the radiators. When you adjust this point, you change the angle of the entire heating curve. The biggest changes occur when outdoor temperatures are cold ‐ see the graph below. If you feel that there isn't enough heat when it is below ‐5°C outside, but there are no problems when it is warmer, you can adjust this point upwards. Adjusting point A on the heating curve. (The factory default setting 55° C is marked with a cross) ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Outdoor temperature 10 ...
Page 11
Point B Adjusting point B means that the entire heating curve moves upwards or downwards (parallel movement). In other words, you don't adjust the gradient for any particular outdoor temperature, rather you adjust the curve for the entire outdoor temperature range. The factory default setting is 0°C, i.e. no movement at all. If you increase this value, the curve moves upwards, i.e. becomes warmer, and if you reduce this value, the temperature drops. This setting is primarily used when you feel that it is too cold (or warm) regardless of the outdoor temperature. (This is also the setting that should be used when first adjusting the heating curve). Adjusting point B on the heating curve. ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Outdoor temperature ...
Page 12
Point C Point C has 2 meanings. On the one hand, it is used to adjust the gradient of the heating curve during warmer outdoor temperatures, but it is also used as a "shutoff temperature" for the heat to the house. When the outdoor temperature reaches this temperature and stays there for at least 8 hours, the Exotic Compact stops sending water/energy to the heating system and thereby shut off heating to the house. During summer time when heat is in off‐mode both circulation pump and mixing valve, which determines the temperature to the heating system, will be run periodically in order to prevent sticking If you feel that there isn't sufficient heating when the temperature is above +5°C outside, but there aren't any problems when it gets colder, you can adjust this point upwards. Adjusting point C on the heating curve. (The factory default value of +17°C is marked with a cross). ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Heating system 12 ...
Page 13
Cracking When the outdoor temperature is around 0°C and it is very windy, slightly warmer water may sometimes need to be sent to the heating system. We call this adjustment, when the outdoor temperature is 0°C, cracking the curve. If you feel that there isn't enough heating when it is around 0°C outside, but it is otherwise sufficient, you can increase this setting somewhat. Adjusting the cracking point. (The factory default value is 0) ‐10 ‐9 ‐8 ‐7 ‐6 ‐5 ‐4 ‐3 ‐2 ‐1 Outdoor temperature ...

Limiting the heating curve Points A, B and C are all used to set the curve in different positions. There are also 3 other ways for adjusting the curve. Basement heating, underfloor heating and room sensors. These 3 settings do not affect the gradient or the position of the heating curve. Instead, they restrict the curve and allow you to set a minimum and maximum temperature that is sent to the heating system. Basement heating Basement heating allows you to cancel the function described in point C, "heat off", which means that the Exotic Compact unit stops sending water to your heating system. If you activate basement heating, Exotic Compact will continue to send water at the temperature you set, even if the outdoor temperature is high. Activate basement heating if you don't want the heating to be turned off even if it is warm outside. This applies primarily when you have a basement that needs a certain amount of heating even in the summertime, or a bathroom with underfloor heating coils that you want to keep warm in the summertime as well. (In the example below, basement heating is set to 25°C) Adjusting "basement heating" on the heating curve. ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Outdoor temperature 14 ...
Page 15
Underfloor heating Underfloor heating is the opposite of basement heating. Underfloor heating limits the heating curve and sets the maximum temperature at which water can be sent to your heating system, regardless of how cold it is outside. Note that your installer must unlock this function in the installer's menu in order for you to be able to view it. Setting a maximum temperature also allows you to protect your underfloor heating system against excessively high temperatures. This setting is only used if you only have underfloor heating. Adjusting "underfloor heating" on the heating curve. ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Outdoor temperature ...

Room sensor A room sensor is a sensor placed in a central location in your house, which provides information to the Exotic Compact unit regarding the ambient temperature. Depending on how your house is designed, a room sensor may work more or less effectively. If you have a large house with many small rooms, it can be difficult to use room sensors because it may be too cold or hot in the rooms that are far way from the sensor. If you have an open plan house, room sensors are recommended, both for the sake of comfort and from an energy efficiency standpoint. If you have a room sensor installed, you can decide whether it should be used to compensate the heating, i.e. be allowed to affect the heating curve. If it becomes warmer than your original setting, the Exotic Compact will reduce the heat to your radiators/underfloor heating system. The greater the difference, the cooler the water that is sent out. This adjustment will take place continuously, which means that the appearance of the heating curve will be constantly changing. For each 1/10 of a degree (0.1°C) that the current room temperature deviates from the set temperature, the temperature in your heating system drops by approximately 4 °C. Block temporarily The button placed on the room sensor can be used for different functions of your own choice. One of these functions is to temporarily block the sensors impact on the heating curve. This function is of interest if you for example have an open fireplace placed in the same room as the sensor. When you add heat to the room with the fire place the sensor will stop the heat to the complete heating system, i.e. all rooms will be affected. However, if you use this function you can set a time delay in hours for blocking of the sensor when you want to use the fire place. When you press the button the activation will be confirmed by 2 blinks from the red diode. Observe that you have to have set this function first in the menu:”Settings”‐>”For customer”‐ >Function button”. Further information in the chapter “Menu function button” Remember! The room sensor cannot increase the heating curve if it becomes too cold inside the house. If it becomes too cold, you need to increase the heating curve manually according to the previous instructions in this chapter. Example of the room sensor function. The set value for room temperature is 21.0°C. If the temperature in the house rises, the temperature in the heating system will gradually decrease. 20,5 20,6 20,7 20,8 20,9 21,0 21,1 21,2 21,3 21,4 21,5 21,6 21,7 21,8 21,9 22,0 16 ...
Why is the heating curve important? Now we have gone through the settings for the heating curve, and the importance of properly setting the heating curve has been highlighted. Why is this so important? Well, the heat pump doesn't act like a oil‐based furnace, wood stove or electric boiler, where the temperature does not have as great an impact on efficiency. The effectiveness/efficiency of the heat pump is called the COP and is a measure of how much energy you get back in relation to how much you put in. COP = 3 means that if you put in 1 kWh of energy, you get 3 kWh of energy back out. The efficiency, COP, of the heat pump depends on many different parameters, but there is a clear connection between the water temperature in the heat pump and COP. The hotter the water that the heat pump must produce, the lower the degree of efficiency, COP, and the lower the cost savings. This means that in order to optimise your savings, the heating curve needs to be set as low as possible. If the heating curve is set too high, the heat pump generates water that is warmer than necessary and therefore has a lower degree of efficiency. The best savings for your heating system come from setting the water temperatures as low as possible! In practice It can take a long time to set up the perfect house heating curve for your house, and you may need ...
Hot water In addition to heating in your home, having domestic hot water available is obviously also important. The Exotic Compact primarily uses the heat pump with its special exchange valve technology to produce hot water. You can influence how your hot water is produced, and your choice will affect both the amount of hot water and the efficiency of the heating system. Just as with heat for your house, which you can read about in the previous chapter, there is a connection between the temperature of the hot water and the savings you can achieve. High temperatures always mean lower savings. Using Exotic Compact's unique hot water exchanger, you can have a good level of domestic hot water with optimal savings. How hot water is produced The Exotic Compact does not have any container or coils with hot water inside the tank, but fresh hot water is produced continuously using a special hot water exchanger. This exchanger uses water both from the lower tank section, which is often somewhat cooler, and from the upper tank section, which always has hot water. The lower tank section preheats the incoming cold water, and the upper tank section is used to top up the temperature so that the water is really hot. The Exotic Compact only heats hot water when you are using it. A flow monitor senses when the hot water is being used and starts a pump that sends water from the lower tank section through the exchanger that heats the warm water. See the diagram below. Exotic Compact Upper tank section Hot water exchanger Lower tank section Flow monitor Circulation pump exchanger Cold water in Hot water out 18 ...
Hot water - settings You can use a number of settings to influence hot water production in your Exotic Compact. Economy or priority One basic decision to be made is whether you want to have extra domestic hot water or whether you want to prioritise saving as much money as possible. In most cases, the economy setting provides enough hot water, but if you have large bath tubs, a jacuzzi, etc. you may want to select the priority hot water setting. Remember! Always start with the economy setting and see whether this provides enough hot water for your needs. Economy The economy setting means that the hot water pump in the Exotic Compact unit has more time to try to heat the water in the upper tank. When you use hot water from the Exotic Compact unit, primarily when showering or filling the bathtub, the temperature in the upper (and lower) section will drop. The heat pump will start when the temperature has dropped a few degrees. If the temperature continues to drop, the electric heater may also need to start. If you use the economy setting, the temperature is allowed to drop further before the electric heater is allowed to start. This gives the heat pump the option of heating up the water instead, which is the most economical solution. Priority The priority setting means that the electric heater starts sooner if the temperature in the upper section of the tank drops. This provides better hot water performance, but it also costs more to heat the water. The figures below show what happens in the economy and priority mode when the temperature in the upper tank section drops. Heat pump starts Heat pump starts 2°C 8°C Electric heater starts Electric heater starts ...
Extra hot water The button placed on the room sensor can be used for different functions of your own choice. One of these functions is the function “Extra hot water”. The function gives the possibility to temporarily increase the hot water performance of the Exotic Compact. This function can be used if for example many people need to shower quickly after each other, many showers used at the same time or if a bigger bath tub/Jacuzzi should be filled. When you press the button the activation will be confirmed by 2 blinks from the red diode. Observe that you have to set this function first in the menu:”Settings”‐>”For customer”‐>Function button”. Further information in the chapter “Menu function button” Observe that it will take at least 15‐30min for the heat pump to increase the tank temperature. No electric heater is used for this function which implies lower costs. Upper tank temperature You can set the temperature that you want to be maintained in the upper tank yourself. As mentioned previously in this chapter, a higher temperature setting costs more, but the level of comfort is somewhat better. If you set the temperature to a very high level, above 60°, this may mean that the heat pump cannot manage to heat the upper tank by itself but needs the electric heater to help out. The factory default setting for the upper tank temperature is 55°C. Try reducing this temperature setting a few degrees and see whether the hot water temperature is satisfactory for your requirements. This allows you to save even more money. If your house (heating system) needs water that is warmer than the temperature that you set on the upper tank section, the heating curve for the upper tank will be applied. 20 ...
Base heat Base heat is the lowest temperature to which the Exotic Compact unit allows the temperature to drop in the lower tank section, even if the heating system doesn't need very hot water. The reason for this setting is so that you can have a good amount of hot water even when your house doesn't need so much heat. This is because the water in the lower tank section is used to preheat your hot water. If you want to increase the amount/volume of hot water, you can raise this value somewhat. Summer charging During the summertime, your house needs very little heating, or none at all. In order to increase the running time for the heat pump and increase the amount of domestic hot water in the summertime, you can set a temperature where the heat pump charges the entire lower section of the tank, so‐ called summer charging. Exotic Compact goes into summertime mode if the outdoor temperature has been above the set value for at least 8 hours. The system remains in summertime mode for at least 12 hours, or for as long as the outdoor temperature is above the set temperature. This is to prevent the Exotic Compact unit from switching between summer charging and heating according to the heating curve during summer nights. Settings that affect the lower tank section temperature. The figure shows "base heat" set at 30°C and summer charging at 20°C Summer charging Base heat ‐30 ‐25 ‐20 ‐15 ‐10 ‐5 Outdoor temperature ...

Installation This chapter is intended for installers of the heating system. ► Note that a commissioning report must be filled in after completing the installation Placement / Moving Place the Exotic Compact indoors in a location with a solid foundation, preferably on a concrete floor. In order to prevent unnecessary noise, if possible, position the heat pump with its back against an exterior wall. • If possible, avoid placing the unit close to bedrooms or other areas that are sensitive to noise. The heat pump module can be easily removed from the tank section in order to lift/transport the product in 2 parts. Exotic Compact has 4 adjustable legs that can be used to balance the tank unit. Pipes to heating system In the basic design, heating pipes are mounted for a top connection. However, both pipes can be ...
Tap water pipe In the basic design, the tap water pipes cannot be angled for bottom assembly without a complete rebuild. As an alternative, customised drain water pipes for a bottom connection can be ordered. Connection pipe bottom installation tap pipe, item no. 97774707001 The flow switch must be removed for a bottom installation. It is very important to check the direction of flow when reinstalling the switch. An arrow shows the correct flow direction ‐ see diagram below. The connection pipes for tap water are designed with a cc measurement of 55 mm in order to make installing a combination of valves easy. Note that the safety valve does not need to be installed as the exchanger volume is below 1 litre. Cold water pipe Hot water pipe Flow switch Hot water circulation Exotic Compact has controls that can be easily connected to a hot water circulation system. This system requires an accessory package that can be ordered from Euronom and includes a hot water circulation sensor and footings. Connecting a hot water circulation system directly to the boiler is not recommended without this accessory kit. Alternatively, a smaller, external hot water heater can be used for connecting a hot water circulation system. ...
Brine medium Dimensioning The collector for earth / bedrock / groundwater / lake heat, etc. should be dimensioned according to a computerised calculation program. Euronom has a dimensioning program and can assist with this type of calculation. Connection hoses Brine medium hoses for the brine system are already installed at the factory and can be removed from the tank on the right or left side. The side plates are perforated at the outlets. Use pliers or a similar tool to cut off the metal blanks on the desired side. Be careful because this can create sharp edges. The brine hoses are marked with the text "Brine in" and "Brine out" with arrows showing the flow. Condensation insulation Since the brine system can become colder than 0°C, all pipes/connectors must be insulated to prevent ice or condensation from forming. Brine fluid The brine medium should contain an antifreeze medium, e.g. bio ethanol, to maintain fluidity down to temperatures of ‐15°C. Collector hose The collector hose, PEM 40 x 2.4 PN 6.3, is used as standard. Every metre of hosing holds about 1 litre of fluid. Aerating The earth heat collector should be installed in a manner that facilitates self‐aerating without any air pockets. If this is not possible, aerating valves will have to be fitted to the highest points in the collector. The level tank should be located at the highest point. Fill coupling Pre‐fabricated couplings, e.g. LK 520 Multifill 25, with integrated valves / dirt filters, are recommended for quick installation in insulated houses. Expansion vessel The expansion vessel or level tank should be installed as high as possible on the incoming brine pipe (brine in).
Brine medium pump A brine medium pump is installed in the heat pump module and has 3 fixed speeds. Different flows are achieved depending on the overall drop in pressure in the brine medium system. A maximum temperature difference of 3 °C between the brine in/out is the ideal. If the difference is too high, the system will issue a low brine flow alarm. The diagram below shows the drop in pressure for the evaporator and the pump curve for the various models. Diagram 1. Pressure drop in the evaporator with 30% ethylene glycol in the brine medium. Compact 5/8 Compact 10/12 Diagram 2. Pump curve Exotic Compact 5/8 Diagram 3.Pump curve Compact 10/12 ...
Electrical installation Electrical installation should be performed by an authorized electrician, in accordance with local regulations. Overview The control unit consists of a connection list of all possible connections and a box for circuit boards and electromechanical components ‐ see the schematic diagram below. An adhesive sticker describes the function of the terminal blocks and how the connection should be set up. The terminal blocks are divided into blocks called A, B, C, D, E and F. Note that this manual only describes how to connect standard components, i.e. blocks A and B. A separate manual will be sent if you are installing any accessories. Earthing bar PE Terminal block fittings Circuit board Cable penetrations Automatic fuse heat pump Power supply block 400 V N Automatic fuse electric heater Automatic fuse circuit board Terminal blocks standard Contactor electric heater, 6 Emergency heat switch Overheating protection reset ...
Power supply The power supply to the Exotic Compact is connected on the power supply terminals up and to the left of the connecting plate. Check the phase sequence before connecting. Based on the maximum power requirements for the system, select the correct fuse and cable dimensions. Max fuse for the product is 32A. The electric heater can be blocked in stages of 1.5 kW in order to limit the maximum connected power. Installing current transformers is recommended (accessories), which provides automatic control of the maximum power based on a main fuse in the system. The table below provides a rough guide to power usage with different electric heater stages connected to the heat pump. Note that the element in the electric heater is 230 V, and if current transformers are installed the least loaded phase will be selected. Table 1. Power usage by heat pump at different power settings for the electric heater. Power electric 6.0 kW 7.5 kW 9.0 kW 10.5 kW heater Phase L1 L2 L3 L1 L2 L3 L1 L2 L3 L1 L2 ...
Terminal blocks The terminal blocks are divided between 2 levels with a spring‐loaded connection. Installation is easy by unloading the spring with a small screwdriver (about 3mm wide), pushing in the stripped cable and pulling out the screwdriver again. Check that the installation is correct by pulling hard on the cable. See also the diagrams below. Also note the marking on the adhesive sticker regarding the upper and lower connection. Upper connection Lower connection Block A – 230V The only high voltage connection to be made apart from the power supply is connecting the radiator pump on block A. Use one of the cable fittings at the top for cable penetration. The earth wire is connected directly to the earth block. ...
Block B – extra-low voltage Block B contains all of the low‐voltage connections that are included as standard with the Exotic Compact. Some of the connections do not need to be connected for the product to work. Communication 1-2 The connection is named "COM HEAT PUMP" on the adhesive sticker. This connection is only used for Euronom's air/water heat pumps and should not be connected. Outdoor sensors 3-4 The connection is named "OUTDOOR SENSOR" on the adhesive sticker. The outdoor sensor has a catch to be opened; tools are not needed. Two spring‐loaded terminal blocks are located inside the sensor. Press the release button and insert the stripped cable to make the connection. Cable to the outdoor sensor should be drawn with a minimum cable area of 0.5 mm and is best mounted on the north or south side of the house so that it is not exposed to the morning sun. The sensor should be placed at about 2/3 of the height of the house's facade and should be mounted to avoid direct sunlight. Make sure that the sensor is not affected by ventilation ducts, doors, windows or similar fixtures which can affect the temperature measurements. Release button Sensor ...
Room sensors 5-8 The connection is named "ROOM SENSOR 1" on the adhesive sticker. The primary job of the room sensor is to transmit information about the room temperature in order to adjust the set house heating curve. This brings overall cost savings because the temperature of the water in the heating system never gets too high. You do not need to use the room sensor function. (It can be turned off in the installer's menu in the display.) However, it is always recommended to install the room sensor because it also includes an alarm diode that flashes if something is wrong. In addition, there is a button on the room sensor that can be used for different functions, e.g. extra hot water, which can be set in the display. In order for the room sensor to work well, the sensor should be placed in as central and open a location as possible in the house. Do not place it by windows, radiators or similar fixtures. Mount the sensor about 2/3 of the way up the wall, and it is best installed in such a way that it is possible to reposition it. The room sensor terminals are marked (1‐4) and should be connected according to the figure below. The tank section's adhesive sticker is also marked with connection numbers 1‐4. Connect the same numbers for the room sensors as for the boiler. Mounting hole Button Sensor Indicator diode Release buttons Cable penetration 1 2 3 4 ...
Current transformers 10-13 (accessories) The connection is named "CURRENT SENSORS" on the adhesive sticker. Current transformers are not included as standard. The job of the current transformers is to continuously measure the current on the incoming phases in the house/system. This measuring helps the program ensure that the power never exceeds the rating for the main fuse by releasing any power‐stage in the electric heater. The current transformers are phase selective, i.e. they measure each phase separately. This allows the system to decide itself which phase to load. This also ensures that the 3 phases are distributed as evenly as possible. Installing the current transformers is recommended but not required. It is possible to limit the maximum electrical power for the electric heater in the display. The current transformers should be installed on the incoming feed to the central control unit, which must be protected against overloads. This should only be performed by an authorised electrician. The minimum cable area for the connection is 0.5 mm². At least 4‐lines must be used. Mount the transformers by threading the incoming phases through the transformer. The blue cables from the transformers should be joined together and connected to the common terminal block 13 Current transformers item no. 4663003 Terminal block Exotic Compact Current transformers Main fuses 52 ...
Error out 14-16 The connection is named "ERROR OUT (MAX 1A)" on the adhesive sticker. The output is potential‐free and has both an NC and an NO connection. It can be used to get a signal to an external unit or to a GSM unit. The output can be loaded with max 1A During normal operations with no alarm, there is contact between terminals 15 and 16. In the event of an alarm or power failure there is contact between 14 and 15 Error or power failure (NC) Normal operations (NO) Digital input 17-18 Connection named "EXTRA DIGITAL IN" on the adhesive sticker. The input should be potential‐free and has different functions depending on what settings are chosen in the display. From program version 1.4 the set function is standby. If the input is closed the heat pump and electric heater will be blocked until the input is opened again. When closing the input below display text will be activated. ****SYSTEM OK***** Standby mode active Heatpump/El.heater blocked. Time 26min ...
