values
■ The specified output is the recommen-
ded connected load.
■ The total output of all components con-
nected directly to the heat pump con-
trol unit must not exceed 1000 W (e.g.
pumps, valves, message facilities,
contactors).
If the total output is < 1000 W, the indi-
vidual rating of a component (e.g.
pump, valve, message facility, contac-
tor) 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 the total current of
5 A).
Set the required parameters during com-
missioning; see from page 59.
