All,
I have 2 RC-80B Stats connected to an HAI Omni-Pro II controller. Both thermostats have worked correctly since installation in June '05. However, one of my thermostats no longer reports current room temperature to the controller... it reports "0" as the temperature. All other functions on this thermostat seem to work, including remote operation.
Lastly, the thermostat's local display shows the correct room temp.
Any advice or suggestions would be greatly appreciated!!!
Regards,
Tony
