Hitting a wall on old system
I thought I'd have this old system up and running by replacing the relay control. I wired and rewired half a dozen times without any response from the system.
By jumping the Y and R terminals I can get the system to open the vent, start the gas, ignite via electric ignition. No pump action and certainly not safe, I just wanted to see if there was anything working at all.
That's the only way I can get ANY response out of this one. I'm just stumped.
Included is the Wiring Diagram off the front of the boiler and a diagram I drew while stumped that shows how I have it wired.
Thanks so much....
