Information regarding the connection
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 (e.g. pumps, valves, message
facilities, contactors) must not exceed
1000 W.
If the total output is < 1000 W, the indi-
vidual output of a component (e.g.
pump, valve, messaging facility, con-
tactor) may be selected larger than
specified. However, the breaking
capacity of the corresponding relay
must not be exceeded.
■ The stated current indicates the max.
switching current of the switching con-
tact (observe the total current of 5 A).
■ Controls for external heat source and
central fault message are unsuitable
for safety LV.
Set the required parameters during commissioning; see from page 110.

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 in ser-
ies as a maximum temperature limiter
for an underfloor heating circuit (if
installed; see page 82).
Connection values:
■ Output: 130 W
■ Voltage: 230 V~
■ Max. switching current: 4(2) A
