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 51 onwards.

Additional
primary pump to increase
residual head
■
Installation outside the heat pump
in the primary circuit flow

No switching via PWM signal from
the heat pump control unit
Supply values
■
Output: 200 W
■
Voltage: 230 V~
■
Max. switching current: 4(2) A
Note
■
The factory-fitted primary pump is
connected to the EEV PCB: See
chapter "Overview of electrical com-
ponents".
■
The factory-fitted primary pump
must be operated at a constant
100 % speed ("Start output pri-
mary source (htg) 7442" at
"100").
