Thermostatic Mixing Valve TM3400 Resideo Honeywell

The Honeywell Resideo TM3400 Thermostatic Mixing Valve It is a high-precision engineering solution, designed for the exact temperature control in Domestic Hot Water (DHW) systems.

Its main function is to guarantee a constant and safe outlet temperature by mixing hot water from the storage tank with cold water. This effectively prevents the risk of scalding, a fundamental safety feature in any modern installation.

This component operates autonomously, without the need for external power, ensuring total reliability even in the event of a power failure.

Key Benefits and Technical Advantages

The TM3400 model is optimized for installers looking for long-term reliability and performance.

• Reliable Scald Protection: This is its most critical function. It limits the maximum temperature of the water delivered to the points of use (showers, taps), protecting users.

• High Degree of Precision: It offers a stable and precise adjustment within the range of 45°C to 65°C.

• Robust Construction: The valve body is made of high quality brassguaranteeing a long service life and resistance to corrosion.

• Autonomous Operation: It operates thermostatically without the need for electricity, reducing the complexity of the installation and points of failure.

• High Flow Design: Its internal engineering is optimized to handle large volumes of water, ideal for central systems.

• Connectivity: Includes direct connection for the recirculation circuit (except in 1/2").

Main Applications and Context of Use

Experience shows that the versatility of the TM3400 makes it ideal for multiple technical scenarios, beyond standard ACS.

• Centralized DHW Systems: Its main application is in residential buildings, hotels and hospitals, with or without a recirculation system.

• Alternative Energy Systems: Essential in facilities of solar thermal energy and biomass (pellet) boilers, where the accumulation temperature can be very high and unstable.

• Underfloor Heating: It is used to limit and maintain the water supply temperature, protecting the pavement and ensuring comfort.
