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 423 Universal Reset Module manages four water temperatures in a tekmarNet system. It provides controls for two single-stage, or modulating, boilers; domestic hot water; and setpoint loads. The 423 Universal Reset Module is tekmarNet 4 compatible, and it possesses several energy saving features, including outdoor temperature reset, to make your system more economical.
Synchronize Your Zones, Save Energy
The tekmar 423 allows your tekmarNet 4 thermostats to communicate with each other. Communication means that your thermostats can synchronize their cycles, when possible, instead of operating independently. This minimizes short cycling, saves energy, and reduces wear and tear on your system.
The tekmar 423 monitors the outdoor temperature and the water temperature at a point in your system. Using this information it is able to determine the most appropriate supply temperature and boiler firing rate. By constantly monitoring conditions and making continuous adjustments, the tekmar 423 delivers unparalleled comfort and efficiency.
Warm Weather Shutdown
A warm weather shut down temperature may be programmed to prevent your system from running when it in unnecessary or untenable.
Automates Boiler Differential
The tekmar 423 Universal Reset Module can automatically adjust your boiler differential to discourage short cycling.

Adding tN4 mixing expansion terminals allows three of the 423's water temperatures to be mixing water temperatures. Find the perfect configuration to maximize your efficiency and comfort.
