Page 6: Sensor Installation
Installation instructions Sensor installation Correct arrangement and installation of the sensors is extremely important for correct functioning of the system. To this end, also ensure that they are completely inserted in their sensor 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 7: Electrical Connection
Installation instructions 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. -

Installation instructions Data cable for DL BUS Terminal diagram, DL BUS data cable The DL bus consists of just 2 wires: DL and sensor earth (⊥). The DL BUS itself supplies the necessary power for the DL BUS sensors. Cables can be routed with a star topology but also in serial formation (from one device to the next). Any cable with a cross-section of 0.75 mm², and measuring up to 30 m in length, can be used as a data link. -

Page 12: Lightning Protection
In order to protect the individual components of a CAN network against indirect lightning strike, we recommend the use of surge arresters specifically developed for BUS systems.

Page 14: Cable Selection And Network Topology
Installation instructions Cable selection and network topology Screened twisted pairs have proven useful in CANopen networks. These are cables with twisted pairs of conductors and a shared external screen. Such cables are relatively resistant to EMC interference and can still carry 50 kbit/s for up to 1000 m. The CANopen recommendations (CiA DR 303-1) for cable cross-sections are given in the table below. - Page 15 Installation instructions 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 termination jumper again.
- Page 16 Changing to cable types with different characteristic impedances is only permitted via signal separation through a CAN bus converter. However, such networks do not comply with the recommended specification. Technische Alternative RT GmbH therefore cannot guarantee trouble-free operation if one of the three options listed above is...

Page 21: Tips On Troubleshooting
Installation instructions Tips on troubleshooting If no voltage can be measured at the outputs even though the relay is switched on, check the fuse (3.15 A slow). The fuse protects the relay contacts from damage through short circuits or overloading. If the status LED indicators are switched off, this indicates failure of the power supply for the electronics. - Page 22 If the sensor is faulty, note the sensor type when replacing. While it is possible to use a different type of sensor, the parameters for that input also have to be set to suit the type of sensor used. The current standard type used by Technische Alternative is PT1000. KTY (2 kΩ) was the standard type until 2010/2011.

Operation Status line The top part of the display shows the output status, messages, faults, date and time. Output status Active outputs are highlighted against a green background. In the following example, outputs 1, 3 and 6 are active. Output 5 has been deactivated manually (Manual/OFF) and output 6 has been activated manually (Manual/ON). - Page 34 The values for geographical latitude and longitude are used to determine the location-specific solar data. That data can be used in functions (e.g. shading function). The factory default settings for the GPS data are for the location of Technische Alternative in Amaliendorf, Austria.

Page 35: Function Overview
Function overview, general Function overview If you are in the main menu, tapping the "Home" button opens the function overview. The function overview can be freely designed by the programmer and can therefore look different on every controller. It can be displayed with the aid of graphics or simply as a table. Values selected by the programmer can be changed either by all users, by Experts only or by Experts and Technicians. -
Page 36: Changing Values
Function overview, general Changing values Tapping the required value opens either a keypad or a selection box. Values can only be changed if they have been enabled for the user level by the programmer. Example: Changing the set room temperature "T.room standard" via a keypad: The keypad then appears: The current value is shown (example: 20.0 °C). - Page 37 Function overview, general Example: Changing the operating mode of the heating circuit with a selection box ("RAS" means that the operating mode is set by the room sensor's slide switch): A selection box appears with all possible settings: When you tap the required setting, it is changed and the required setting is displayed in the function overview.

Page 38: The Most Important Functions
Function overview, general The most important functions The most important functions for the user are: • • Heating circuit Individual room control • • Time switch DHW demand • • Calendar Solar control Various setting parameters for these functions are described in the following: Heating circuit In the heating circuit function, the set flow temperature is determined for the heating circuit and the heating circuit pump is switched off or on according to adjustable shutdown conditions. - Page 39 Heating circuit function Settings for the heating circuit operation with an additional link to the heat curve parameters: You can change the internal operating mode of the function by changing the Operation setting. RAS indicates that the setting of the room sensor is applied. If there is no room sensor installed, the setting Time/auto applies the time switch's time program to the heating circuit.
- Page 40 Heating circuit function Settings for the heat curve: Room influence: If a room sensor is installed, you can use this setting to define how much influence the actual room temperature should have on the calculation of the set flow temperature. Values higher than 50 % will have a very great influence and will be unfavourable in most cases.
- Page 41 Time switch Time switch The Time switch function is used to define the changeover between T.room standard and T.room setback in the heating circuit. The function can be programmed for a single heating circuit only, or jointly for several heating circuits. The "Time switch" can also be used to switch other functions or statuses.
- Page 42 Calendar Calendar The calendar function overwrites the internal settings and specifications of the time switch for the heating circuit. The following calendar modes can be set: • Holiday • Party • Bank holiday • Standby There are up to 10 date windows available in which each mode can be set. Up to 3 set values can be set in each mode, one of which can be applied in the heating circuit as the set room temperature.
- Page 43 Individual room control Individual room control This function is specially designed for the control of zone valves for heating and/or cooling of individual rooms. Room temperature thresholds and the operating mode switch on the room sensor can be utilised to switch between heating and cooling. Shutdown conditions prevent heating or cooling beyond the outside temperature thresholds.
- Page 44 DHW demand DHW demand This function is used in many systems to define the domestic hot water cylinder temperature. The Demand is currently set to OFF, so the effective set temperature is only 5 °C. You can define the set temperatures via the Settings key (gearwheel): The DHW demand can be switched between two set temperatures via a time program from the Time switch function.
- Page 45 Solar control Solar control The solar control starts or stops a solar pump based on the differential between the collector temperature and a reference temperature (e.g. temperature at the bottom of a cylinder). Option: use of a limit sensor (e.g. temperature at the top of the cylinder). Start conditions for the solar pump: 1.

The guarantee includes free repair (but not the cost of on-site fault finding, removal, refitting and shipping) due to operational and material defects which impair operation. In the event that a repair is not economical in the opinion of Technische Alternative for reasons of cost, the goods will be replaced.
