Just added a new Navien combi-boiler and the Nest now continues to send power via the red lead once the room comes to temp. Lower the temp on the nest, signal is still being sent. Turn off the nest, still get the need heat signal. Wiring is set up correctly (two wire with a hot common). Even tried removing the batteries, the nest still sends the on signal.
Does anybody at Google actually read or respond to these posts? My solution so far was to put a Honeywell thermostat on, now it works like a champ.
