Features

    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

  • By constantly monitoring conditions and making continuous adjustments, the tekmar 423 delivers unparalleled comfort and efficiency.
  • Warm Weather Shutdown

  • tekmarNet 4 Expansion
  • This tekmar control contains four expansion terminals, which allow you to add tekmarNet 4 controls into your communication system. Adding tN4 mixing expansion terminals allows three of the 423's water temperatures to be mixing water temperatures.
