Building drying – General Information A special application of the universal controller UVR65 is the energy-saving and cost-effective drying of basements and other building parts via regulation of ventilation. The special functionality of the sensor RFS-DL (measurement of absolute humidity) enables the comparison of the values for abso- lute humidity indoors and outdoors to turn a fan on or off.
Choosing a building drying program automatically binds inputs and external sensors according to the table below to reduce the amount of necessary manual setup. These settings can of course be changed, if so desired. Input Ext. Sensor Value Absolute humidity indoors Absolute humidity outdoors Temp.
Program 690 – Room drying, minimum temperature monitoring, comfort ventilation A room‘s humidity is to be reduced. If it becomes too cold in the ventilated room, the fan is deacti- vated. In order to guarantee a certain degree of air quality, the fan is activated despite exterior humidity or if the room temperature falls below a set minimum.
Program 692 – Room drying, room temp. monitoring, comfort ventilation, for wine cellars A wine cellar‘s humidity is to be lowered. To ensure a certain level of air quality, the fan is activated despite exterior humidity. The fan is activated via one or more time windows, preferably in the cool morning hours.
Heating circuit control - Programs All heating circuit programs (except program groups 816 and 976 as well as other stated exceptions) require the following settings: Overview Technician level: Time/Date Menu Parameters Mode (preferably Auto) Basic parameters Time programs Heat curve Expert level: Set flow temp.

Installation instructions Sensor installation Correct arrangement and installation of the sensors is extremely important for correct func- tioning of the system. To this end, also ensure that they are completely inserted in their sen- sor wells. The cable fittings provided serve as strain relief. When used outdoors, no water must be allowed to penetrate the sensor wells (risk of frost).
Page 81
• DHW sensor: A rapid reaction to changes in the water volume is extremely important when using the controller in systems that generate domestic hot water by means of an external heat exchanger and variable speed pump (freshwater module). Therefore fit the DHW sensor directly on the heat exchanger outlet.
Device installation CAUTION! Always disconnect the mains plug before opening the casing! Only work inside the controller with the power cable disconnected. Unscrew the screws on the front and lift the cover. The electronics are located in the cover. The connection to the terminals in the lower section of the enclosure is made by contact pins when the cover is put in place.
Measurement drawing of casing (in mm) Electrical connection Caution: This must only be carried out by a qualified electrician in accordance with the rele- vant local regulations. The sensor lines may not be fed through the same cable channel as the supply voltage.

Connection auxiliary relay HIREL-22 Connection of a three-way mixer to the analogue outputs A4 and A5 The auxiliary relay is not to be mounted in the device itself, as it has its own casing. This connection plan only applies to program groups 832 and above.
Take the „BUS load“ into consideration as sensors have a relatively high current demand: The controller UVR65 supplies a maximum bus load of 100%. The bus loads of the electronic sensors are listed in the technical data of the relevant sensors.
CAN-Bus network Terminal CAN-Bus line Guidelines for the topology of a CAN network Technical principles The CAN BUS comprises the cables CAN-High, CAN-Low, GND and one +12 V supply cable for bus components without their own power sup- ply. The combined total load of all devices with 12 V and 24 V supply must not exceed 6 W.

Page 93
Bus rate In the CAN BUS / CAN settings menu of the UVR65, the BUS rate can be set to between 5 and 500 kbit/s, whereby lower BUS rates enable longer cable networks.. However in this case, the cable cross- section must be increased accordingly.
Page 94
Wiring A CAN BUS network should never have a star topology. Rather, the correct topology is a line from the first device (with terminator) to the second, third and so forth. The last bus device has the termina- tion jumper again. Example: Connection of three network nodes (NWN) with a 2x2-pole cable and termination of the ter- minal network nodes (network inside one building) Each CAN network is to be provided with a 120 ohm BUS terminator at the first and last network sub-...
CAN-Bus – Output values The controller sends the same set of data to the CAN-Bus, in the form of analogue and digital values. If a value can‘t be sent (for example: value of an external sensor that isn‘t connected) the output will read zero.
Operation – Basics Device overview The display on the front shows information about sensor measurements, menu position, parameters and such. The bar on the right side of the display moves along with the vertical position in the cur- rently opened menu (= scroll bar). The wheel to the right of the menu serves to navigate through menus.

Usage as room sensor RASKTY RASPT Usage as room sensor RASPT Usage as insolation sensor GBS Fixed value Assign a fixed temperature value to the input.
Due to the relatively high power drain of external sensors, pay attention to the bus load: The controller UVR65 supplies a maximum bus load of 100%. The electronic sensor FTS-50DL, for example, has a bus load of 25% – a maximum of 4 such sensors can be con- nected to the DL-Bus.
Setting up external sensors DL-Bus sensor Designation Each sensor can be given its own designation here. This designa- tion only serves the purpose of identification and has no influence on operation. Source The source from which the signal is being read out. In this case, „DL input“...
Outputs In this menu, each used output has its own sub menu, in which each can be given a designation that has no influence on opera- tion. Below that, settings for run-on time and blocking time can be found (further details below). Additionally, several infos and sta- tistics are displayed, such as Mode (Auto/Manual), and meter readings for running hours and impulses („total“, „today“...
Run-on time Especially solar and heating pumps with long hydraulic pipelines may have issues with con- stant turning on and off again over longer times when attempting to start up. This is espe- cially disadvantageous for modern high-efficiency pumps. Such behavior can be avoided by specific usage of the speed control or by setting up a run-on time.
Control output The two control outputs (A4 and A5) are identical in terms of parameterization. The parameters concerning the control outputs are found in this menu. As analogue output, 0-10 V can be generated in 0.1 V steps. In the mode PWM, a digital signal with a frequency of 1 kHz (level approx. 10V) and a variable duty cycle of 0 to 100% is generated.
This example will be used to describe the different possibilities for speed control. Absolute value control = maintaining a sensor‘s value S1 can be kept at a certain temperature (such as 50°C) very well by using the speed control. If the insolation sinks, S1 becomes colder. The control unit then lowers the speed and hence the flow rate.
Differential control = to keep the temperature between two sensors constant Keeping the temperature difference between two sensors, e.g. S1 and S2, allow for a „mod- ulating“ operation of the collector. If S1 drops due to sinking insolation, the difference be- tween S1 and S2 sinks as well.
Event control If a set temperature threshold (set value event) is exceeded at the activation sensor, the event control starts, keeping the temperature at the control sensor constant (controller set value). If S3, as exemplified, reaches 60°C (activation threshold), the collector is to be held at a con- stant temperature.
Stability problems The speed control contains a „PID controller“. It ensures an exact and fast adjustment of the actual value to the set value. In applications such as solar systems and charging pumps, the factory settings likely regulate in a stable manner. Especially the DHW preparation via external heat exchangers (fresh water station) adjusting these values to the specific circum- stances is absolutely necessary.
Output mode, Correcting variables Depending on the make of the pump, the control mode of the pump can be set to normal (0-100 „solar mode“, PWM 2) or inverse (100- 0 „heating mode“, PWM 1). There may also be specific require- ments for the limits of the control range.
System protection There are two functions for excess collector temperature limitation, two for frost protection, and a cooling function. Except for the first excess temperature limitation, all of these func- tions are deactivated in the factory settings. Excess temp. limiter Steam might build up in an idle system, making a reactivation difficult, as the pump can‘t lift the fluid above the highest point in the system (the collector feed line).
Frost protection This function is deactivated in the factory settings and only necessary for solar systems that have no frost protection of their own. Souther latitudes offer the possibility of bridging the gap of the few hours below a collector minimum temperature with power from the solar sys- tem‘s cylinder.
Collector cooling function Using this function, a solar system‘s cylinder can be cooled overnight to allow it to take in warmth again the next day. If the chosen sensor (cylinder temperature) exceeds the specified temperature, the speci- fied outputs will be activated within the specified time window until the temperature is un- derrun again.
Start function (ideal for tube collectors) Some solar systems might not be sufficiently bathe the collec- tor sensor in the warmed heat transfer medium in the morning, resulting in an unfavorably late start of circulation. Flat collec- tor panels generally tend to lack sufficient gravitational force. The starting function attempts find a good point to activate the solar pump by constantly monitoring the collector‘s temperature.
monitored outputs Outputs which are to be monitored. If one of these outputs is active, no starting function attempt will be made. Range: Combi- nation of all outputs (FS = A1, FS = A2) Flushing outputs Outputs used for flushing. If a control output is assigned to the output, the analogue level for full speed will be output.
Page 125
Pump run Pump run time in lower priority. If the time increase in temperature during flushing does not suffice to switch into higher pri- ority, lower priority will be permitted for this time. If the pump run time is set to 0, lower priority will only permitted once the higher priority consumer reaches its maximum threshold (= absolute priority)
Funct. check (Function check) The function check serves to monitor a system for sensor defects or missing circulation in a solar system. The function check is deactivated in the factory settings. Function control Activate/deactivate (FS = No) Yes/No Sensors will be monitored to detect inter- ruption and short circuits.
Heat meter (3 identical entries) The device offers the possibility to log heat quantities in 3 different sections of a system. The 3 heat meters are deactivated in the factory settings. A heat meter requires 3 basic in- puts: flow temperature, return temperature, flow rate (volume flow) In solar systems, adequate mounting and placement of sensors (see installation instruc- tions –...

If the heat meter has been activated, the following points will displayed in the overview: current yield in kW volume flow in liters/hour heat quantity in kWh WARNING: If one of the two sensors (flow, return) of the heat meter has an error (interruption, short circuit), the current yield is set to 0, so no false measurements will be added to the heat quantity.
Step-by-step setup guide for heat metering Two volume flow sensors are available to choose from: • pulse encoder VIG • volume flow sensor FTS..DL, connected via DL-Bus If no volume flow sensor/encoder is used, a fixed volume flow can be specified.

No volume flow sensor/encoder: Activate the heat meter profile as in the previous guides. Specify the flow and return sensors in their respective menu points. Choose „-----“ as flow sensor, since none is in use. Specify the fixed flow rate. Enter the assigned outputs, frost protection share and calibrate the sensors, as described in the previous guides.

Temp. threshold This temperature must be exceeded at the specified sensor for the duration of the hold time. The affected output is switched on (if the function becomes active) for the duration of the hold time and held above the temp. threshold. Affected output These outputs are switched on, if the function becomes active.
Drain-Back This additional function can only be activated with programs for one collector field and one consumer (e.g. programs 0, 80, 112, 432 etc.) or program 4. With drain-back solar thermal systems the collector area is emptied outside the circulation time.

Heating characteristics The flow temperature is usually calculated from the temperature outdoors and the heat curve (settings: menu Technician level/Parameters, Control type: Temperature or Slope). The heat curves are calculated for a set room temperature of +20°C and are shifted in a par- allel direction in correspondence to other set room temperatures using the set room tem- perature influence.
Heat curve With both methods, the influence of the outside temperature on the flow temperature is not linear. For the mode Slope, the curvature is designed according to the norm. For the mode Temperature, the specification of the desired flow temperature at 10°C (outdoors) causes a „curvature of the heat curve“.
Frost protection This functionality becomes active in standby operation in any operation status, even if the heating circuit would block the pump due to a shutdown condition. The frost protection function becomes active, if the median outdoors temperature (see menu Expert level/Mixer) goes below T.outside frost, if the flow temperature goes below Act.
Timer This functionality equals an astable timer. Changing the linking (And/Or)*. Assign outputs Runtime Pause time The timer function offers the possibility to assign a runtime (output is activated during this time) and a pause time (output is deactivate during this time) to an output. Runtime and pause time are activated alternately.
Manual mode Changing of the individual outputs‘ mode of operation. Choice between Manual/ON (Output constantly on), Manual/OFF (Outputs constantly off) and Auto (Output regulated according to usual automatic operation and time windows). Only outputs used in the chosen program or ones that have been assigned a functionality (Expert level/Programming settings/As- signmt of free outputs) are displayed here.

Usage as room sensor RASKTY RASPT Usage as room sensor RASPT Usage as insolation sensor GBS Fixed value Assign a fixed temperature value to the input.
Due to the relatively high power drain of external sensors, pay attention to the bus load: The controller UVR65 supplies a maximum bus load of 100%. The electronic sensor FTS-50DL, for example, has a bus load of 25% – a maximum of 4 such sensors can be con- nected to the DL-Bus.
Setting up external sensors DL-Bus sensor Designation Each sensor can be given its own designation here. This designa- tion only serves the purpose of identification and has no influence on operation. Source The source from which the signal is being read out. In this case, „DL input“...
Outputs In this menu, each used output has its own sub menu, in which each can be given a designation that has no influence on opera- tion. Below that, settings for run-on time and blocking time can be found (further details below). Additionally, several infos and sta- tistics are displayed, such as mode (Auto/Manual), and meter readings for running hours and impulses („total“, „today“...
Run-on time Especially solar and heating pumps with long hydraulic pipelines may have issues with con- stant turning on and off again over longer times when attempting to start up. This is espe- cially disadvantageous for modern high-efficiency pumps. Such behavior can be avoided by specific usage of the speed control or by setting up a run-on time.
Control output The two control outputs (A4 and A5) are identical in terms of parameterization. In most heating circuit programs, the two control outputs are already used to control the mix- er and can therefore not be used for other applications. In this menu, the parameters for the functionality of the selected control output are adjusted.
Absolute value control = keeping a sensor‘s value constant The absolute value control is set via two parameter windows. The example shows typical settings: Mode: Off/Normal/Inverse Normal operation means that the speed increases along with temperatures and is valid for all applications to keep a „feed sensor“...
Event control If a set temperature threshold (set value event) is exceeded at the activation sensor, the event control starts, keeping the temperature at the control sensor constant (controller set value). Example: Mode: Off/Normal/Inverse Activation sensor: The sensor which activates the event control. Control sensor: Sensor that is to be held constant, if the event control activates.
Stability problems The speed control contains a „PID controller“. It ensures an exact and fast adjustment of the actual value to the set value. In applications such as solar systems and charging pumps, the factory settings likely regulate in a stable manner. The proportional component represents the reinforcement of the deviation between the de- sired and the actual value.
Output mode, Correcting variables Depending on the make of the pump, the control mode of the pump can be set to normal (0-100 „solar mode“, PWM 2) or inverse (100- 0 „heating mode“, PWM 1). There may also be specific require- ments for the limits of the control range.
Shutdown conditions Room temp. shutdown Deactivation of the heating pump if the current room set tem- perature is exceeded. Enable „ON“ shows further settings: Diff. off: Difference to the room set temp. (can‘t be lower than Diff. on) Diff. on: (Re-)Activation difference Set flow temp.
Mixer Room influence Influence of the room temperature on the mixer‘s behavior Start excess in percent, assuming a setback time of 10 hours. The previous setback time leads to an increase (which recedes over time) of the flow temperature to shorten the heat-up time. FS = 0% Mixer run time Total mixer run time (FS = 3min)
Funct. check (Function check) The function check serves to monitor for defective sensors. The function is deactivated in the factory settings. Function con- Activate/deactivate function check (FS = No) trol Yes/No Sensors are monitored for interruptions and short circuits. Sensors of the type Digital (ON/ OFF) or VIG, and sensor inputs set to Fixed value or to unused are not monitored.
Heat meter (3 identical entries) The device offers the possibility to log heat quantities in 3 different sections of a system. The 3 heat meters are deactivated in the factory settings. A heat meter requires 3 basic in- puts: flow temperature, return temperature, flow rate (volume flow) To increase precision, the share of anti-freeze in the heat transfer medium must be speci- fied, since anti-freeze lowers the heat capacity of the medium.

Fixed flow rate Volume flow in liters per hour. If no volume flow sensor was specified, a fixed flow rate can be set up instead. If the assigned output is inactive, the flow volume is assumed to be liters/hour. Since speed control makes for a constantly shifting volume flow, this setting is not suitable in combination with speed control.

Notes concerning precision: The precision of all measured energies and energy flows depends on many factors, which will be looked into deeper here. • PT1000 temperature sensor of class B have a precision of ± 0.55 K at 50°C • The error of the device‘s own measurement stands at typically ± 0.4 K per channel For an assumed spread of 10 K, these two measuring errors result in a maximum measuring error between the flow and return of +/- 1.90 K = +/- 19.0 % for class B and +/- 13.0 % for class A.
Step-by-step setup guide for heat metering Two volume flow sensors are available to choose from: • pulse encoder VIG • volume flow sensor FTS..DL, connected via DL-Bus If no volume flow sensor/encoder is used, a fixed volume flow can be specified. The necessary settings are illustrated step by step below.

Pasteurisation Enable Enable/disable pasteurisation to prevent the cultivation of legionella (FS = No) Interval time Interval in days. If the temperature measured at the moni- tored sensor does not exceed the specified temp. threshold within this time interval for the hold time, the affected out- puts will be activated.
CAN-/DL-Bus Node number in the CAN network Designation of the device within the CAN network Bus rate in the CAN-Bus (must be the same for all devices in the network!) This point allows the activation/deactivation of data output via the DL-Bus for Datalogging or the remote display of the RAS+DL.
On the device itself, the only necessary settings are that which allow it to be accessed via CAN-Bus. As for the C.M.I., the CAN node number of the UVR65 (= source) and the data record x2 must be spec- ified under Settings > Data logging.
