Question
Thermostat turns on Furnace and A/C at the same time?
I installed the unit using the 4 wires into the correct slots at the back and installed it on the wall as directed. I updated the time and date and then altered the pre-set timing for the on/leave/return/sleep modes without changing the temp settings, just the time settings. Before I went to sleep last night, after the sleep setting, i raised the temperature to 74 from the preset of 68. When I left the house this morning at 8:10am (the leave time is set to 8am) it was still 74 on the thermostat and the air conditioner was running as well. I set the front panel to heat when it was installed. Why would both be running? I did not alter the 'cool' settings at all?
Thanks
