For nearly three decades, tekmar has been providing zoning and control solutions for a variety of heating and cooling applications. Products made by tekmar can improve the efficiency and comfort delivered by almost any system. The tekmar 444 Mixing Expansion Module is a component in a hydronic tekmarNet 4 system. Mixing water temperature is requested by tN4 thermostats through a tekmarNet system control. The 444 then operates a system pump and a mixing device, either a floating action mixing valve or a variable speed injection pump, to provide the mixing water temperature for your system. Alternatively, it may operate a mixing device that requires a 0-10 V (dc), 2-10 V (dc), 0-20 mA, or 4-20 mA signal. The 444 Mixing Expansion Module is an excellent way to increase the number of water temperatures in your system without sacrificing connectivity.
The tekmar 444 Mixing Expansion Module monitors the mixing supply temperature and makes continuous adjustments to improve system efficiency and provide optimal comfort.
