Trying to install thermostat - unable to locate type c in control board

Post by niroshthanga »

Hi,
I am trying to install a smart thermostat that requires common wire (type c).
Can i get some assistance in locating the common wire in the control board?

Attaching picture of the EWC control board and model
Appreciate your insights

Smart thermostat's will not work with this zone board. You are going to need to update the board to a NCM 300.

Thanks for prompt response.
I do have 4 thermostat with the control board i have currently, NCM 300 would work correct?
Reason: NCM 300 has limit of 3 zones and if i have 4 zones, do i need to upgrade to something else?
Or number of thermostat is irrelevant.

Please advise so that i can go ahead with the purchase.

You will need to upgrade the NCM to the Bmplus 5000 that will give you 5 zones
