Main PCB (operational components 230 V~)
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.
Set the required parameters during commissioning;
see from page 73.

Terminals Function Explanation
211.1 Fan Connection values:
■
Output: 200 W
■
Voltage: 230 V~

211.2 Secondary pump
■
In systems without a heating water buffer cylinder, no
other heating circuit pump is required (see terminal
212.2).
■
Connect the temperature limiter to restrict the maxi-
mum temperature for underfloor heating systems (if
installed) in series (see the following chapter).
