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):
max.
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 specified current indicates the max. switching
current of the switching contact. Observe total cur-
rent of 5 A.
■
Safety LV is unsuitable for controlling external heat
generators.
Set the required parameters during commissioning:
See page 66 onwards.
