Connection possibilities for the PCB (SCU-
X03)
The control PCB SCU-X03 can control a modulating central heating
pump. Depending on the make and type of pump, the pump can be
controlled by a 0-10 V, 4-20 mA or PWM signal. The speed of the
pump is modulated, based on the signal received from the boiler.
For correct connection of the pump, see the documentation
supplied with the pump.
