*Residence had a 1000 ft2 addition built at time of house control retrofit.
When the difference in yearly temperatures are factored in, savings were even higher.
Outdoor Temperature Reset saves energy by adjusting a boiler’s operating temperature according to the current outdoor temperature.
Indoor Temperature Feedback adjusts your boiler based on actual building indoor temperatures. This adjustment for heat loss & heat gains caused by people, appliances, the sun, wind or any other factor provides a much higher level of comfort & efficiency!

EASY SELECTION: House Controls are selected to match mixing and zoning requirements. All models provide control of on/off or modulating boilers and DHW.
COMFORT: Indoor temperature feedback improves comfort by accurately maintaining the selected temperature.
EFFICIENCY: The system automatically adjusts boiler supply temperatures to match what the building actually needs.
NO CALLBACKS: There’s no need to fine tune the outdoor temperature reset curve later in the heating season. Indoor temperature feedback does this automatically!
COMMUNICATION: tekmarNet® communication offers more than improved system operation. It opens the door to remote accessibility.
