Definitions
Waterfurnace - The Waterfurnace Geothermal Heating/Cooling system.
Burn - using a gas term to indecate geothermal compressor operation.
Degree Day - the number of degrees in a day is defined as the difference between a reference value of 65°F (18°C) and the average outside temperature for that day.
Fan ON - The system uses the fan to move air from one zone to another as well as supplying warm/cool air. When Fan time on exceeds Burn time the system is saving energy use moving air within the house to where it is requested without firing up geothermal unit.
Aux Water Heater - When the Geothermal system is not able to meet Domestic Hot Water needs, the propane heater is utilized. Highest demand occurs when no heat/cooling are required.
