controller lockout - controller or other component problem?
I've been having a problem with one of my properties heating systems. The controller has been replaced a few times now because it keeps "locking out". My plumber/boiler tech' is stumped and can't quite figure out what is going on. We started with a Wilkerson controller and initially thought that the controllers where bad because the controllers kept going into lockout. We know have a Honeywell R8184G 4009 and this controller is also going into lock out mode. Does anybody know what might be causing this lock out problem?
Ive been doing some reading on this controller application, installation, troubleshooting
and Im starting to understand some of the components and the functions they provide.
What are the ramifications of replacing the cad cell with a jumper with the right ohms range? I would suspect that the controller would sense that the system is operating as it should be.
Could a clogged tank filter cause the nozzle to clog and trip the cad cell? The system was cleaned in September of this year and was tested to have about 83% efficiency. Co2, draft all seemed to look good. Or, at least did when it was cleaned. My boiler tech also did something called punching down the fingers for better heat transfer.
When looking into the boiler during initial fire-up what should the flame look like? Looks like a Yellowish / Orange flame of good size 2-3 diameter with ragged edges.
Any help or advice would be very very helpful
