Information regarding the electrical connections
Installation and service instructions of the rele-
vant heat pump
The total output of all components connected directly
■
to the heat pump control unit (e.g. pumps, valves,
signalling equipment, contactors) must not be in
excess of 1000 W.
If the total output 1000 W, the individual rating of a
≤
component (e.g. pump, valve, message facility, con-
tactor) can be greater than specified. However, the
breaking capacity of the corresponding relay must
not be exceeded: See following chapter.
■ In the delivered condition, terminals may have been
pre-allocated (depending on appliance version).
If 2 components are connected to the same terminal,
press both wires together in a single wire ferrule.

■ The KM-BUS wires are interchangeable.
■ The Modbus wires are not interchangeable.
The neutral and earth conductors of all components
■
are connected as follows, depending on the heat
pump type:
– Terminals X2.N and X1.
PCB
– Terminals X2.N and X1.
Note
Only the connections to be made are shown in the fol-
lowing PCB diagrams. Pre-allocated connections
made at the factory are also explained in the tables.
