Functions:
• Shuts off and opens suplly remotely: solenoid de-energised = control valve open.
• Float pilot is used as a security in case of problem with the remote controller. The float pilot controls obviously a higher level than the controller.
Applications:
• Control remotely the filling of a drinking water reservoir with on/off supply. Float pilot acts as a security in case of power failure.

Good to know! Solenoid controls in priority the filling of the reservoir. In case of power failure, the float modulating pilot replaces the function of the solenoid automatically!
