*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.
What Made the Difference?
Outdoor Temperature Reset with Indoor Temperature Feedback
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!

House Control Advantages
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.
