I have an all electric a/c heating air forced unit and I'm trying to figure out the wiring. On my old thermostat, I had the R = Red 1+ = White 1- = Blue C = Orange
On the nest thermostat, where do these wires go?
Thanks.

The + and - are data wires for a communicating thermostat that talks to the furnace.
To use a Nest or any other standard thermostat you would need to go to the equipment and move the wires over to the terminal strip that has the standard labels on each screw. Such as Y G W R C. And also on the outside unit you would have to move the wires.
If you take the cover off the indoor unit there is usually a decal with wiring diagram showing the thermostat wiring for communicating and standard thermostats.

My one question: If I have a Lennox HVAC that is using their thermostat, can I change it over to a Google Nest Learning thermostat and have fun functionality of my Lennox HVAC? The reason I am asking is two fold: 1) I heard the thermostat I have now does tend to malfunction over time; and 2) I read that the Google Nest Learning Thermostat cannot give fun functionality to the Lennox HVAC. Thanks.

Hi there,
I know it has been a while, and I'm sorry for the delay.
To ensure your systems' compatibility with the Nest Thermostats, could you please share with us your thermostat's wiring? This is to ensure how wires are being labeled.
I'll look forward to your response.
Regards,
Mark
