Re: Swapping out an ST series zone control to model NCM-3z zone control
Specific questions:
1. Do I need a new Common for System? NCM-3z manual shows one but the ST-2E did not have one connected.
2. Is my motor/damper configuration correct? Anything else look off/out of place?
3. I do not plan to use the orange and blue wires that are currently connected to the board ...
