Question about Honeywell Programmable Thermostat Heater
I would recheck your wiring..... Shut the furnace off at the breaker or SSU.... Then get a pen and pad and write down the color of wires and where it is connect on the Terminal strip at the furnace..
Example: Red wire hooked to R terminal etc They should all match up with the subase of the new Thermostat.
Then go up to the thermostat and Check and make sure the colors match what you have wired at the furnace. R= Power W=Heat G=Fan Y=Cooling C=Common
There are two possible ways the heat could be power on all the time..... You have the white wire or W wire wired to G and the thermostat is set to Fan ON... or the insulation on the R wire and W wire is split and touching each other or they got pinched and are touching together which will make the furnace come on with out the thermostat controlling it..... Good Luck, Its is where I would start first.... there our other possibilitys the control board may of gone hay wire.....
