ALARM Honeywell RM7800 L 1012 Fault 110
I have a Fault code 110 on my Honeywell controller. I have checked the jumpers and they are in the same state that they are programmed to be in. I can't seem to figure out what has caused this problem all of the sudden. Does anyone have any insight on what to look for while troubleshooting a fault 110.
The model is RM7800 L 1012 this is on a modualting firetube boiler.
