Multi-module operation (MSR 2)
Important:
The external supply voltage is important for multi-module operation, so that the other modules can continue
to be operated while the master controller is being serviced.
If consumers are supplied with external power supply, the correct connection of the neutral conductor has
to be observed. In this case, there exist two different neutral conductors that may not be interconnected.

External power supply
* in the multi-module arrangement, the power for the thermostatic pump
must be sourced externally. Switching off the controller at the main switch
would also switch off the thermostatic pump and thus prevent further
operation of the other modules, owing to overtemperature.
