Nest Thermostat

Post by vgjmoro18 »

I'm trying to hook up a Nest thermostat. My existing Honeywell thermostat as six wires. B, G, O, R, Y, W. The Nest thermostat has one port for both O and B. My EWC panel is Model EWC-ST-2D. What do I do?

Thank You

You need to change zone board to a NCM-300. Any questions call 1800-446-3110-X490.
