TYPE A: HEAT PUMP OR AIR CONDITIONING
TYPE B: HEAT PUMP ONLY
which installation has been programmed.
The heat pump can operate all year and allows the user to make energy savings due to the plenum temperature regulation function (exclusive to
Stelpro). This function ensures a constant temperature into the plenum and the ducts. When it is cold, the heating capacity of the heat pump is
reduced. For type “B” installation, the furnace will compensate for the capacity loss of the heat pump. Even when the defrosting mode of the heat
pump is activated and begins to cool the air, the furnace will quickly increase the heating capacity in order to offset the cooling effect caused by the
defrosting mode of the heat pump.
