Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
If you have to switch from heat to cool, then tou don't have an automatic thermostat ---- you have a programmable heat and cool thermostat. For cooling mode you have to program in the temperatures you want for the various times of the day and days of the week. If you have a fan selector for auto or on, switch to on and see if the fan works. Let me know the results.
