Short in Honeywell TH8110R1008

Does anyone have a contact number for Honeywell Thermostats. I awoke to a very warm zone. My Lochinvar Noble was running at 10% firing rate and the temperature was 76 although the thermostat was set to 68. Looks like the back plate that holds the thermostat to the wall has a short in it. When I press on the terminal strip it stops and starts again.
I called TACO and they help troubleshoot the issue back to the thermostat. So I removed the base and installed another thermostat (Honeywell Pro 2000) and did not have the same issue. Boiler only fires on a call for heat. Its a great thermostat so I'd like to get a replacement base.
Any ideas

If pressing on the board fixes the issue it's likely a bad solder joint, not a short.
That said, I'm betting you'll be buying an entire thermostat. I don't believe they sell just the wall plate.Single pipe quasi-vapor system. Typical operating pressure 0.14 - 0.43 oz. EcoSteam ES-20 Advanced Control for Residential Steam boilers. Rectorseal Steamaster water treatment0 -
Some HW stats have a 5 year warranty......how old is this one?0

Cheaper and easier to get a new stat!0

I would guess that the relay that closes R-W is stuck......if effect a short across the relay/switch.
If you try to fix it, then any warranty would go away. IMO
Find the paperwork on it and maybe the warranty terms are shown there.0
