Control box power supply: 230V 50Hz + Ground terminals 1,2 and 3.
Terminals 4 to 15 are dedicated to P1, P2, P3, (P4) 230V power supply.
Do not exceed 3A per pump.

230V 3 points actuator
Opening of the actuator is made sending 230V pulses between terminals 16 (N) and 18 (+).
Closing of the actuator is made sending 230V pulses between terminals 16 (N) and 19 (-).
Terminal 17 (permanent Phase) can be used with return to zero (RTZ) actuators.
3 points 230V and 0-10V signals (or pulses) are sent continuously even if they
are not wired.

*For each of these inputs / outputs, the second wire must be connected to the
common terminal 37 or 31 as per available space.
There is no polarity on all contacts and temperature sensors.
Temperature sensors’ inputs except S1 are already wired. To add a temperature
sensor, remove existing wire from the terminal and isolate its end. Connect the
sensor’s wire instead and its second wire to common terminal, 31 or 37.
