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 set point, or is adjusted using dew-point reset with a humidity sensor. A backup boiler can provide an Outdoor Temperature Reset water temperature as well as domestic hot water and set point 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.
