I have a thermostat that is for a carrier heatpump and radco/carrier electric furnace (attic). The heat pump works but there is no option to switch to emergency heat like moderm units.
Is this a defect or is it meant to switch automatically? Is there a way to test the backup/furnace heat? I had the heat about 5 degrees above room temp and the heat pump was still running not the furnace.
Around here, especially on older homes, heat pumps usually do not kick over to backup heat if raised more than 2 degrees over the room temp.
Could be the wrong thermostat. Does the air handler have electric heating elements? If it does, I’ve never seen any that weren’t switched independently.
Maybe it does not have emergency heat. It is an optional “kit”. Often marked on the data plate, have a photo? (Most southern homes do not have the kit)
That is possible. This heat pump is supplimental. The vents come from the attic. But there are floor vents on a different system that operate independently.
Some in my area have a switch on a control board located at/near the furnace. On the one below, moving the switch to standby will bypass the heat pump and cause the furnace (back-up/emergency heat) to come on.
