Honeywell V4044F1000B Three-way zone valve, 3/4″ IT 230V/50Hz, with help switch

The 3-way zone valves with electric actuation are used for two-point control as a mixer or distribution in hot water heating and domestic hot water (DHW)systems. They are particularly suitable for systems with circulating pumps and DHW priority circuit where a pressure increase in the DHW system and in the pipe network of the heating system shall take place. Depending on the application, they are controlled by a room thermostat or a boiler temperature controller in the heat exchanger which controls the domestic hot water heating. The built-in auxiliary switch (type F) is used for automatically on and off switching of the circuling pump and boiler, or other control device.
