In Reply to: wiring up my Taco SR504 relay.......... posted by Craig on December 16, 2007 at 14:58:03:
I understand where the wires fore the thermostats go and I understand where the wires for the circulators go. I'm unsure of how to connect the wiring from the aquastat to the the relay. There are no zone valves in this system just circulators. The aquastat has four wires going to it black, red, white, and green, they travel to a Honeywell switching relay, which is being replaced by the SR504 relay. I'm only confused about where to put the wires for the aquastat.
