Information regarding the connection values
■
The specified output is the recommended connected
load.
■
Total output of all components connected directly to
the heat pump control unit (e.g. pumps, valves, mes-
sage 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 relevant relay must not
be exceeded.
■
The specified current indicates the max. switching
current of the switching contact. Observe total cur-
rent of 5 A.
Set the required parameters during commissioning:
See page 67 onwards.

Terminals Function Explanation
211.2 Secondary pump Supply values
■
Output: 140 W
■
Voltage: 230 V~
■
Max. switching current: 4(2) A
■
In systems without a heating water buffer cylinder, no
other heating circuit pump is required: See terminal
212.2.
■
Connect a temperature limiter in series to restrict the
maximum temperature of underfloor heating circuit (if
installed).
Secondary pump is connected at the factory. Connect
the temperature limiter on site.

ted at the factory
Supply values
■
Output: 10 W
■
Voltage: 230 V~
■
Max. switching current: 4(2) A
