Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
There seems to be a phantom setting in my chronotherm III thermostat. It puts the heat up at 4:40 am to 66 degrees, when the wake mode starts at 5:40 am at 66 degrees. The program is still in sleep mode at the time and sleep mode is at 62 degrees. I have disconnected, taken out the batteries to restart and it still does it. Any ideas ?
