Wiring diagrams
The heating zones 1 and 2 can be controlled by the remote control (TA1) or the ambient
thermostat (TA2) that can be connected to the boiler boards; zones 3 and 4 are activated
directly by the ambient thermostat connected to the relevant zone board. Zones 3 and 4
cannot support control by the safety flow line thermostat (TSM), which must be mounted in
series on the pump power supply line and will not be detected as a fault.
The solar collector probe (SCS) and the solar tank heater probe (SBS) are maintained on
the boiler board. The solar valve probe (SVS) must be connected to the additional board.
