The heat pump is not deciding whether or not to heat.JamesW-
FWIW, I spent 2 hours with Pentair UltraTemp support yesterday. I was told several times that the UltraTemp has a 2° Delta for the desired temperature.
That's just ridiculous.pool will heat above the set point 3 degrees,
I do adjust to set point so it reaches the max that I want. The differential is adjustable between 3 and 9 degrees though I haven’t tried it higher than 6.I guess I don't see why the heater continues to run for hours when the set point is reached.
Are you adjusting the set point to make it turn off where you want?
Can't you adjust the differential?
