Where is the outdoor temp sensor located.
What brand and model number is your outdoor unit.
Most newer heat pumps can efficiently provide heat down to about -10°F outdoor temp.
Both of them are frigidaire By Nordyne. Model #'s for them are:
Heat Pump Model FT5BD-048K
The outdoor temp is located on the wall beside my heat pump. It was reading 32 degrees when I heard the heat pump would come on cycle 20-40 secs and turn off. I thought this was bad for the heat pump so thougt lock it out below 35 degrees...
My installer said that heat pumps dont work below 30 degrees in florida so I assumed he is correct.
