Okay, this is good news...you most likely are using 24 volt, and NOT 120volt.mcguirehg wrote:yes...we are using Taco multi zone.....?
Did you check them fuses yet?
And while you are at it check the fuses in the Taco.
And make sure the relays in the Taco are seated...give a little push and wiggle in.
Not sure why the Amtrol controller has all the color wires connected if using a Taco Control???
Guess I better ask...Taco Zone...is it zones by circulators (SR) or zones by zone valves (ZVC)?
