Hello - I want to replace an old Honeywell Thermostat with Nest Learning.
the current thermostat has wiring 1,2,3,4 and the compatibility guide says its not compatible. However, i have exactly the same Heater & A/C units connected to 2 other Nest Learning Thermostats in the house. Nest Support validated that the Heater and A/C brand and model are supported by the model of Nest Learning Thermostat that i have
The question I have is, “how do I map the current wires to the Nest”
Attached is the picture of my current Thermostat and wiring. Looks like i have all the required 5 wires
Appreciate any guidance on how to proceed.
One of my other NEST has the following wiring configured and working well. Will this work for this one as well?
