Heat pumps use refrigerant to extract warmth from outdoors to warm dwelling regions. Should you be considering buying a warmth pump, Check out with your local HVAC seller about out there HVAC Strength tax credits.
TC stands for Thermocouple. TC is really a form of temperature sensor consisting of two wires of various metals joined at each conclusion. It is actually Typically Employed in gas furnaces and sizzling h2o tanks for valve and Procedure controls.
ODT means Outdoor Thermostat. ODT is a thermostat Situated outdoors the building made use of to control a secondary heating system when the surface temperature fall below the setpoint.

HAP is actually a twin perform program - full-highlighted load calculation and system sizing for professional structures in addition multipurpose hour-by-hour Vitality modeling. It offers graphical enter capabilities for promptly assembling a 3D constructing product. Thermal loads are calculated using the ASHRAE® Warmth Stability load strategy.
MUA means Make Up Air. MUA is needed for any exhaust system to perform well. In the event the air within a area is staying fatigued out, the home becomes negatively pressurized.
