The factory-provided inserted bridge between the two clamps named WSK, must be
removed, if connected to a pump with winding protective contact. If no connection is
carried out, it needs to be remained screwed in. The clamps lead mains supply!
For a proper operation of the electronic motor protection, the motor current has to be
driven via all three contact points of the filter control (clamp L2 and L3 and U1 and V1
bridged, pump connected to W1).

The floating relay contact between the clamps 22 and 23 can be charged with a
maximum voltage of 230V with maximum 4A.
If the heating needs 230V, this required voltage can be obtained from the existing L1
clamps, which are sufficiently available in the PC-25. There are also clamps available
for the N-connection of the heating.
For the control of a 400V three-phase-current heating, an external contactor has to
be connected, that controls the heating.
In order to protect the heating against overheating, a flow monitor or a safety
thermostat can be inserted instead of a bridge between clamp L1 and 22.
For a solar-heated operation a
-solar-actuator 230V can be connected to the
clamps U2 and U3. With a solar operation, clamp U2 drives the mains voltage and
clamp U3 is dead circuit. If the solar heating is not controlled, clamp U2 will be dead
circuit and clamp U3 will drive the mains voltage. These contacts may be charged
with maximum 230V/1,5A.
