NCM 300 Nest TSTAT

Post by rick62783 »

I purchased 2 nest tstats and need to confirm if they will work with my set up. I currently have 18/6 run to each existing tstat and they are only using 4 of the 6 wires. I was told by google that I would need a control wire but they couldn't confirm that my unused wires would work. I am assuming I can take the unused Blue wires and connect to the C for each tstat on the control panel and then connect to the C on the new tstat. Am I missing something? See attached pics for existing setup

You just need to hook up the "C" Common wire to the NCM 300 and the Nest thermostat and you will be good.
