Electrical connection
All electrical installation work is to be
performed by specialist companies.
Disconnect the voltage supply when
connecting the electrical terminals.
Observe the VDE guidelines.
! CAUTION
■ Limit switches are integrated in the
actuator of the 3-way switching
valve.
■ The actuator requires a continuous
operating voltage of 230V/1~/50Hz.
This must be connected to the black
(L) and blue (N) wires. In this state
the valve is in resting position. This
corresponds to heating position and/
or opening of the path I<->II.
■ The valve is actuated if the brown
wire of the actuator is additionally
connected to a voltage
of 230V/1~/50Hz. The valve
then moves downwards until
it reaches the limit switch. This then
corresponds to the position for hot
water / cooling / opening of the path
I<->III. The valve remains in this state
until the voltage from the brown wire
is switched off again.
■ Every heat pump has appropriately
labelled connection terminals for
the connection of the actuator.
Observe the instructions
in the installation manual of the heat
pump for the correct connection.
