We just purchased a new house and I have been trying to set up our previous Nest thermostat with no luck.
When the Nest unit is wired it blows hot air.
- I factory restarted the Nest unit. Still blew hot air.
- I switched Y1 & G and it still blew hot air.
- Took Nest off and rewired old unit back in and cold air is blowing again.
What is being wired wrong on the Nest unit?
1st photo - is the old unit’s wiring before install.
