Weil-Mclain - Honeywell controller issues
I installed a used Weil-McLain 68 oil-fired boiler. The problem is the unit wants to fire and run whenever I power it on - through the breaker. The thermostat is off and it still runs. I even disconnected the thermostat wires and it will still fire and run when I flip the breaker on. I've checked the controller - its a honeywell but I can't find anything with a model number on it - and the transformer clicks back and forth if I arc the thermostat terminals. When it fires - the pumps don't run, unless I have the thermostat wired back up and set to run. I've turned the unit from vertical to horizontal and that doesn't do anything either - I was wondering if it mattered. Any help I can get (before it gets too cold!!) would be greatly appreciated.
