Electrician installed the thermostat (electric in-floor heating model) yesterday. I wasn’t around, so it was past the 15 minutes allowed to do set up. Tried resetting the thermostat - Pressed the up/down arrow, didn’t work. I’ve also done the circuit breaker, and disconnected the faceplate for 30 minutes.

Nothing is allowing me to get into pairing mode. I get the smiley face all of the time, never the down area that indicates pairing.

So frustrated. Any suggestions?
