I have a honeywell thermostat currently. Only a red white and blue wire
labeled as 1, 2, and 3 respectively when I take the cover off. I cannot
get the nest to accept all three wires. Any advice? Thank you
Hi Douglas, I have heating and cooling. I have found another thread
where someone had a similar numerical setup with Honeywell as well. It
is my understanding I have a proprietary wiring system for my home that
is not nest compatible without rewiring...
