NCM 300 - Zone Issue
I had a new system installed in April 2021, system has a total of 4 zones, First floor and used EWC ND 5 dampers to control 3 room in a finished basmt. we used Nest Tstat in bsmt. The control of zones is not working at all correctly, each tstat controls 2 zones, not the related zones associate with the tstat zone 1 tstat opens zone 2 and 3 , tstat 2 controls zone 1 and 3 etc. i checked all wiring its associated correctly, zone 1 is zone 1 dampeners etc, only one , i take off the 24v and the power light on dampeners goes out. The board LED zone lights are suppose to be on when closed ,system not calling. they all stay light when no demand is calling. tried to troubleshoot with guide all shows ok. could the board be bad?

It could be a bad board. But I am going to need you or some one there at the board to take some readings with a volt meter.
Can you give me a call.
