Tekmar Controls 406 Control

Tekmar Controls 406 Control

The tekmar 406 House Control is an advanced tN2 system controller specifically engineered for hydronic heating and cooling applications. This microprocessor-based station manages two-stage air-to-water or water-to-water heat pumps while seamlessly integrating a backup boiler or electric resistance heat source. Designed for professional HVAC contractors, it simplifies multi-stage heat pump operation by providing precise outdoor temperature reset for radiant heating and dew-point reset for radiant cooling. With four on-board 24Vac zone valve outputs, this control is highly versatile and expandable up to 52 zones when combined with additional tN2 or tN4 modules, ensuring rapid deployment in large-scale residential and commercial systems.

Built-in zone synchronization logic optimizes equipment operation, reducing short-cycling and increasing efficiency across the entire hydronic HVAC network. The tekmar 406 supports domestic hot water (DHW) priority and features intelligent heat/cool switchover to maintain comfort levels without manual intervention. Technicians can leverage the away/vacation mode and indoor temperature feedback to fine-tune system response. This unit is housed in a durable NEMA 1 enclosure and mounts on a standard 4x4 electrical box, making it a reliable standard for radiant floor cooling and modern energy-efficient retrofits.

Key Benefits
  • Dual-Stage Integration: Efficiently sequences two heat pump stages alongside auxiliary backup heat for maximum reliability.
  • Precise Reset Controls: Utilizes outdoor reset for heating and humidity-aware dew-point reset to prevent condensation during floor cooling.
  • Massive Scalability: Manages 4 zones out of the box with the capacity to scale to 52 zones for complex hydronic layouts.
  • Automated Efficiency: Zone synchronization and intelligent switchover ensure equipment groups run only when necessary.
  • Domestic Hot Water Support: Includes dedicated DHW priority and post-purge settings to optimize tank recovery times.
Common Questions
  • How do I prevent condensation during radiant cooling? The 406 uses an adjustable setpoint or dew-point reset with a humidity sensor to keep chilled water temperatures above the dew point.
  • Can this control manage both a heat pump and a boiler? Yes, it is designed to operate a heat pump as the primary source with a backup boiler providing outdoor reset temperatures or DHW.
  • Is the tekmar 406 compatible with tN4 thermostats? Yes, the control features expansion ports that allow connection to tekmarNet 4 components for expanded zoning capabilities.
