My Taco hydronic control box does not have a "c" terminal. How do I install the nest power controller. There are multiple 24 volt relays controlling 110 volt circulating pumps.

Hi greenie8,
Thanks for reaching out to us. If your multi-zone Taco control box for a hydronic heating system doesn't have a C terminal, you may refer to our Pro Installation Guideor call Pro to install it for you.
Best,
Zoe
