My house has two zones. I need help in wiring a Nest Learning Thermostat to either zone. On the first floor zone, I have both an Orange and Blue wire, but the Nest has only one connection O/B. Neither zone uses the C-Wire so I am not sure if I should purchase the Google Nest Power Connector. Below are the photo's of the furnance controller & schematic and the Honeywell thermostat base.
So is the Nest Learning Thermostat compatible with this furnance controller? and how should I wire each zone? Should I get a Google Nest Power Connector to provide a C-wire?
Thanks for your help.
