values
■ The output given is the recommended
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 < 1000 W, the indi-
vidual rating of a component (e.g.
pump, valve, message facility, contac-
tor) can be greater than specified.
However, never exceed the breaking
capacity of the corresponding relay.
■ The stated current indicates the max.
switching current of the switching con-
tact (observe the total current of 5 A).
■ Safety LV is unsuitable for controlling
