Question about Honeywell Programmable Thermostat Heater
I installed a Honeywell RTH230B digital thermostat on a new gas furnace. With the mode switch on "heat" and the fan switch on "auto", bumping the temperature up does not cause the furnace to run. I moved the fan switch to "on" and the fan started, but not the burner. I then removed the thermostat and jumped the red and white wires together and the furnace started right up. I thought - bad thermostat- and bought another one. It did the same thing. I checked the instructions and they mention a 3 minute delay for cooling, but not for heating. Any help would be appreciated.
Sometimes there's a differential setting anywhere from 1-3 degrees, see if you can make sure it's down to 1
