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 66 onwards.

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.
