Just installed a wired Insteon thermostat. It works fine for AC and I can set the fan to "Always" just fine. But in Heat mode, when the heat setpoint is reached, the furnace does not come on. On the thermostat, the screen goes blank, then starts up again (all LCD segments display momentarily, then the current temp, time and humidity display), then goes blank, etc. -- It appears the thermostat is rebooting over and over again. The furnace is a single stage, forced-air gas furnace -- nothing special. I checked and rechecked the wiring -- seems correct and as I said, the AC works fine.
Ideas appreciated.
