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 402 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 402 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 402 delivers unparalleled comfort and efficiency.
