4 Commissioning
First make all electrical connections correctly and only then carry out the
commissioning!
▶ Follow all installation instructions for all components and assemblies
in the system.
▶ Only switch on the power supply when all modules are set up.
NOTICE:
Risk of damage to system through pump failure!
▶ Fill and vent the system before switching it on so that the pumps do
not run dry.
4.1 Setting the coding switch
If the coding switch is in a valid position, the status indicator lights up
green continuously. If the coding switch is in an invalid position or an
intermediate position, the status indicator does not light up initially, then
starts to flash red.

4.2 System and module commissioning
4.2.1 Solar system settings
1. Set the coding switch.
2. Set the coding switch on other modules as applicable.
3. Switch on the power supply (mains voltage) to the entire system.
When the module indicator lights up green continuously:
4. Commission and set up the user interface as described in the
accompanying installation instructions.
5. Select the installed functions in menu Solar settings > Change solar
configuration and add them to the solar thermal system.
6. Check the settings for the solar system on the user interface and
adjust them to suit the installed system if required.
7. Start the solar system.
4.2.2 Settings in transfer and primary store systems
1. Setting the coding switch at the MS 200:
– for the primary store system with low loss header to 6,
– for the primary store system with heat exchanger (TS...-3 or
SLP.../3) to 7,
– for the transfer system to 8.
2. Set the coding switch at other modules, if necessary.
3. Switch on the power supply (mains voltage) to the entire system.
If the status indicators on the modules light up green continuously:
4. Put the control unit into operation as described in the accompanying
installation instructions and make the appropriate settings.
5. With coding switch position 6 and 7: set the primary store system in
the menu DHW settings.
With coding switch position 8: in the menu Transfer settings >
Change transfer configuration select installed functions and add to
transfer system.
6. Check the system settings at the control unit and, if required, adjust
transfer parameters or DHW system I settings.
In systems equipped with heat interface units, the buffer cylinder
temperature should be at least 5-10 K higher than the set DHW
temperature of the heat interface units.

Example configuration of solar thermal system 1 with functions G, I
and K
1. Solar thermal system (1) is preconfigured.
2. Select and confirm Collector array 2 (G).
Selecting a function automatically restricts the functions that can
subsequently be selected, to only those that can be combined with
the functions that have previously been selected.
3. Select and confirm Therm.dis./daily heat-up (K).
As the Therm.dis./daily heat-up (K) function is not available in
every solar system, this function is not shown in the illustration even
though it has been added. "K" is added to the name of the solar
system.
