Honeywell V8044C1081 three-way zone valve

The 3-way zone valves with electric actuator can be used for two-point control as a mixer or distribution in hot water heating and domestic hot water systems. They are especially suitable for systems with circulating pumps.   Depending on the application, they are controlled by a room thermostat or boiler temperature controller in the heat exchanger of hot water. The built-in auxiliary switch (type F) is used for automatically switching on and off of the circulation pump and boiler, or other control device.

Version F = with auxiliary switch (5-wire)
Version C = without auxiliary switch (3-wire)
