Lets eliminate or pinpoint issue being in thermostat. Remove R and W wires and touch tem together and tell me if heat comes on.
Next verify if you put R to R or RC and if you left jumper in place
Did you touch R and W?
OK did heat come on touching R and W?
OK issue is not with thermostat. Go to furnace and see if we have an error light flashing on board , If not touch R and W on furnace board and see if heat comes on.
Not sure, but jumping R and W bypasses thermostat taking it out of the picture
If connecting R to W (actual wires from furnace) does not bring heat on there is an issue with furnace or wiring. The thermostat is just like a light switch.R is hot from furnace. On call for heat the contact closes and sends that hot leg back to furnace. Jumping R and W takes the thermostat out of the picture.Go to furnace and see if there is an error code flashing on board,If not jump R and W on furnace board and tell me if furnace comes on.
Your problem is not with thermostat That green light is telling us there is a problem with furnace such as an open limit.I believe if you connect old thermostat right now it will not work.Do you want to try before we troubleshoot furnace?
That makes absolutely no since.The thermostat closes circuit between R and W to make heater come on. You must not have been connecting them good.
Loosen one screw and stick both wires under one screw and tighten. I am going look at thermostat manual again while you do this.
THat should bring heat on
Then lets look at setting on new thermostat.
Lets look at the thermostat menu and just make sure nothing got changed.
Enter setup menu by pressing and holding UP and DOWN arrows simultaneously until display changes.,
Then make sure Function 5 is set for 5
Was 5 already on 5?
Lets put new thermostat back and try one more time. I am stepping away for about 10 minutes but will be right back
WEll glad we were able to get it working.Strange why it would not come on jumping R and W, just maybe not a good enough connection. So are we all done?
My bad. No you need to move them back to R and W respectively
Not at all, nothing but a bypass. Is everything working properly now?
Separate the wires back. Place the white in W and Red in R... You still have thermostat bypassed.
Wow. I am starting to think maybe you got a DOA thermostat. I would take it back, tell them you had a licensed hvac guy help install and it would not work.
