Electric heater?

[nwirt74@gmail.com]

So, this morning the outside temperature was 48 degrees, inside our coach the t-stat read 58 degrees. I turned thermostat to the electric heat pump setting, the gas heater came on instead? So, after it reached a temperature of 68 degrees, I turned the setting down at which time it cycled off. After a few minutes, I turned the setting up to 70 degrees to see if the heat pump would come on, again the gas heater came on once again? Any ideas as to why the heat pump is not coming on? Haven’t used any heat since early spring!

Normally, the gas heat will come on until the set temps are within 2-3 degrees of the air temp. At that time, the electric heat will then take over and stay on keeping the temps.

In colder temps, I set the electric heat to 2-3 degrees over the air, as it gets to temp, I keep setting the temp higher until I get to the temp desired. That is, if I am NOT using my LP....

If the inside is 3-5 degrees difference than the tstat setting the furnace will start along with the heat pump, once the inside temp stabilizes the heat pump should come on by itself unless/until the inside temp drops below that preset differential.
FYI, the heat pumps are only efficient down to about 40+/- degrees outside temperatures, once the heat pump isn't able to maintain the inside temp the furnace will start.
Once the temps drop to below freezing outside be sure to run the furnace occasionally as there's a duct from the furnace ran into the underbelly to help keep tanks & water lines from freezing.
