The relay output cannot be assigned any function. The relay is inactive.
Compressor stage 2 K2
Relay is used for the control of a second compressor (refer to compressor 2)
Process reversing valve Y22
Control of process reversing valve Y22. The process reversing valve is required for
changeover from heating to cooling mode and for the heat pump’s defrost function.
Hot-gas temp K31
The relay is energized when a connected hot-gas temperature sensor B81 or B82
exceeds “Setpoint hot-gas temp” (2849), and deenergized, when the temperature drops
by the switching differential (2850) below the setpoint. The type of contact (2851) can
be selected.
Electric immersion heater flow K25
The relay is used for the control of an electric immersion heater in the flow (K25) or, in
the case of a 2-stage electric immersion heater, for control of the first stage.
Electric immersion heater flow K26
The relay is used for the control of the second stage of an electric immersion heater in
the flow (K26).
