Information regarding the connection values
■
The specified output is the recommended connected
load.
■
The total output of all components connected directly
to the heat pump control unit (e.g. pumps, valves,
message facilities, contactors) must not exceed
1000 W.
If the total output is < 1000 W, the individual rating of
a component (e.g. pump, valve, message facility,
contactor) can be greater than specified. However,
the breaking capacity of the corresponding relay
must not be exceeded.
■
The stated current indicates the max. switching cur-
rent of the switching contact (observe the total cur-
rent of 5 A).
■
Controls for external heat source and central fault
messages are unsuitable for safety LV.
