The tekmarNet ®2 House Control 406 is designed to operate the equipment in a 2-pipe, single tank, hydronic heating and cooling system. It operates two heat pump stages (water-to-water or air-to-water) with a backup heat source (boiler or electric resistance). The heat pump provides either hot or chilled water to a storage tank loop and optional mixed temperature loop. For radiant heating, the water temperature is calculated using outdoor temperature reset. For radiant cooling, the chilled water temperature is maintained at an adjustable setpoint, or is adjusted using dew-point reset with a humidity sensor. A backup boiler can provide an outdoor reset water temperature as well as domestic hot water and setpoint water temperatures. The 406 operates 4 on-board heating and cooling zones and is expandable up to 52 zones on the boiler, tank, and mix water temperatures.

SPECIAL REQUIREMENTS This control is designed to mount on a 4” x 4” electrical box, and must use tekmarNet ® thermostats to communicate heat demands. For floor cooling or hydronic cooling with a fan coil, use tekmarNet ® 2 thermostats 527, 528, 529, 530 or tekmarNet ® 4 thermostats 537, 538, and 540 with a date code of December 2011 or newer. www.tekmarcontrols.com
