Model 8800 thermostat (I have 5 / problem with only 1): a)

Customer Question

Model 8800 thermostat (I have 5 / problem with only 1): a) my ability to select "Auto" mode (for heating/cooling - not the fan) has "disappeared". b) the "Inside" temp reading on the thermostat seems to be pegged at 83 degrees while I have selected 74 degrees (Hold) for this and all other units in my house. I know the temp in the zone in question is not is not 83 degrees. I know the a/c unit is pushing cool air. c) When I push "Hold" the temperature seems to default to 85 ... I reduce the temp to 74 in "Temp Hold" mode. I have never programed this device. No humidistat or heat pump. Any suggestions appreciated.
