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 403 House Control controls two water temperatures. It is equipped to operate a system pump and four zone pumps in addition to a two-stage, or modulating, boiler or two single-stage boilers in order to satisfy heating, DHW, and setpoint demands in a hydronic system. This control also manages a mixing device, such as a variable speed injection pump or a floating action mixing valve. The 403 House Control is tekmarNet 2 compatible, and it possesses several energy saving features, including outdoor temperature reset, to make your system more economical.
Synchronize Your Zones, Save Energy
This tekmar control allows your tekmarNet 2 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.
tekmarNet 4 Expansion
The tekmar 403 contains two expansion terminals, which allow you to add tekmarNet 4 controls into your communication system. Find the perfect configuration to maximize your efficiency and comfort.
The tekmar 403 monitors the outdoor temperature and the water temperature at various points throughout the system. Using this information it is able to determine the most appropriate supply temperature, boiler firing rate, and mixing valve position. By constantly monitoring conditions and making continuous adjustments, the tekmar 403 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 403 House Control can automatically adjust your boiler differential to discourage short cycling.
