I have a Hayward HeeatPro HP21002 heat pump. I turned the heater on to heat the pool for the kids to swim this weekend and everything seemed fine. In the first 12 hours the pool went from 61° to 75°. About 16 hours later I went to check the pool temp and it still sat at 75°.
First, I am sure the thermostat was set correctly. I had it set at 90°. Ambient temp during the day was near 80° while the temp at night was down in the upper 50's to near 60°.
I'm at a loss as to why it would heat but not all the way up to the temp I had selected. I was thinking maybe a bad thermostat??? The heater was running though. It seems if the t-stat was bad it would shut the unit off. Ideas welcome...
