Honeywell Thermostat Wait

I have a Honeywell TH8320U (VisionPro 8000 Series) TSTAT. The A/C unit is a Trane with AC / and a Gas furnance. The thermostat (when in heat mode) stays on 'WAIT' the entire time heat is requested. Nothing happens for hours, it just says 'WAIT' If I remove the TSTAT from the wall and then select heat, the 'WAIT' does not appear and the internal relay clicks on. I can then put the thermostat back on the base unit/ wall the heat will run.

I had an AC tech come out and diagnose the problem. He said he thought it was the thermostat needed to be replaced. I switched it out with another and the same thing is happening, so it must not be the thermostat? It has natural gas heat. When the system is in cool, the A/C portion works fine and 'WAIT' does not appear. It is only when the system is selected to heat that this 'WAIT' problem shows up. **UPDATE** I pulled the panel off the gas furnace and I looked at the circuit board.

It was replaced last summer by the same service company due to the A/C not working. They had common (in this case the blue wire from TSTAT) hooked to the W terminal which also had the white wire from the TSTAT hooked to it. Ceragon software download. I moved the blue wire to the Common terminal on the curcuit board and now the heat is working fine. 'WAIT' no longer appears.

I am puzzled as to why they had it wired like that. However, the A/C worked fine all summer despite that.

Mar 23, 2017 - New Homeowner (December) and I need help troubleshooting. Everything was peachy keen until I returned from a week vacation. A/C will not. Heat Pumps and Electric Home Heating - Honeywell Thermostat says Wait - It has said 'Wait' for awhile now. Tried and checked breakers. When I switch the faceplate with a faceplate that did.
