Hey guys, was hoping some of you may have experienced a problem like this in the past. I recently had my thermostat updated to a new Honeywell model and my furnace will not click on automatically. I don't know if this was an existing problem or something brought on by the new thermostat. In order to get around this problem I've had to flick the fan toggle to ON - This will turn both the heat and the furnace on and blow heat out until I turn it off.

I have attempted numerous times to set the temperature to a degree higher than the room temp with the fan on auto, this always forces a click from the thermostat but nothing happens afterwards, so you can see my confusion.

I was thinking the wiring may not be correct but since I am no heating expert I thought I might run it by you guys first, thanks for reading!
