Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
Well, here is the deal: unless you rewired from two wire to multiple (usually 4 to 10 wires) wires, the fan cannot be controlled from the thermostat, even though the thermostat indicates that it can > it is a physical wiring and fan administration issue.
Unless you have a newer furnace, the fan is controlled by plenum temp. Works like this: burner turns on, no fan until the plenum temp reaches set temp,....then burner off, and fan keeps running until pelnum temp drops, and often the fan may kick on a few more times as this temp depletes.
