Mc, the clock does not advance nor does it switch or cycle. I think its because the clock dial does not advance. I took the pins out of the dial, and to be honest, I'm having a difficult time getting them back into the dial.
I'm at a loss how to set this thing. The inner case under the dial refers to different color pins. I've seen others with more pins. What gives with these timers? Also, I've heard that if the timer malfunctions while in cycle that the boiler can stay in a fire mode. How can this be if it is wired to aquastat, presuretrol etc?
By the way, on the last pic, isn't the boiler room a nice place to be? Do you think the uninsulated 4 inch drop down header might have anything to do with this????
