Information regarding the connection
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 (e.g. pumps, valves, message
facilities, contactors) must not exceed
1000 W.
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 stated current indicates the max.
switching current of the switching con-
tact (observe the total current of 5 A).
■ Controls for external heat source and
central fault messages are unsuitable
for safety LV.
Set the required parameters during com-
missioning; see from page 74.
