TH-Fill

Reservoir filling control module for solenoid valve
Tank filling control by level probes or buoys, and control of a solenoid valve at 24V, in a 3-module wide box for DIN rail mounting with 230V power supply.
It has front indication of voltage presence and solenoid valve position (open or closed), as well as front potentiometers for adjusting water sensitivity (hardness) and delay time before opening and closing the solenoid valve (surge).

Operation: When the tank level drops below the minimum probe, the solenoid valve opens and remains open until the level reaches the maximum probe. There is always a delay in the opening and closing of the solenoid valve, which can be adjusted.

The output contact is a voltage-free relay contact. It is activated and deactivated at the same time as the solenoid valve, and can be used to activate a tank filling signal.
