Controlli S300 Actuator terminal details.
Resolution
L=Neutral
L'=230Vac
B=Close signal from thermostat or control device
R=230V to thermostat or control device
V=Open signal from thermostat or control device
To test: Place a wire link between R and B, the valve actuator will close, place a wire link between R and V, the valve actuator will open.
If a auxiliary switch kit D22 is fitted, this can be used to signal the boiler/pump to start if the installation was a domestic.
