I have split system. Unit outside and other part under the house. It A/C and Heat unit also. Goodman unit. I have totaline thermostat p/n p474-0100
last 2 days when I come home heat has been stuck on. The system outside is not on. But im getting heat. It feels like EH (emergency heat) is what is on. But on Thermostat is does not show EH on. Now when I hold bottom O and ^ then it shows the EH on and red light comes on. Then when i hold buttons again light turns off and EH goes away but heat is still going. I have already called tech. Just would like to know what to look for and watch what he is going to be doing.
right now settings for Thermostat is:
Step#2 (display type dual or single) 2 Step#4 (heat pump) on Step#5 (reversing Valve pofanity) O Step#7 (Deadband) 2 Step#8 Min Diff heat/cool 2 Step#9 cycles per hour d Step#10 therm backlight on Step#11 F or C F
