Hello,My Carrier electronic thermostat is connected to a heat pump. It was set to the COOL position during a summer thunderstorm when the AC suddenly began running no matter what the SET temperature was. It works normally when I change it to the AUTO position. The HEAT and EHEAT positions work normally.I tried cutting power to the unit for 2 days, after which it worked normally even on COOL, but after a short power failure it resumed the problem of running the AC continuously.I keep it on AUTO now, and it works fine for both heating and cooling. Any ideas on making it work on the COOL setting again?
