Modulo Compact : zone valves

Zone valves are the most convenient way to regulate the temperature of different system parts. For example, a thermostat or chronothermostat must be linked to a zone valve, which opens or shuts the valve based on the room temperature and the set comfort temperature.

The end switch on the Emmeti Modulo and Modulo Compact zone valves closes when the valve is open and may be used to turn on a circulator or boiler.

Is it always necessary to connect the end switch in a zone valve?

The micro end switch of an electronic zone valve is simply a contact that closes when the valve is open (2-way) or sends the water in one possible direction (3-way).
It can activate a circulator, boiler, or heat pump, but if you don't need it, you don't need to connect it.

Are Modulo Compact zone valves compatible with older models?

How many wires are necessary to connect a zone valve?

To connect a zone valve, it is necessary to have a phase and neutral connection (2 wires) and one wire connected to the thermostat, which brings phase to the specific connector of the zone valve.
