    Boiler Controller Honeywell RM7897 Resetting code 110 (200hr lockout)

    Quick synopsis,
    Boilers installed 12 years ago.
    Boilers working.
    New Boiler Inspector finds the controllers, Honeywell RM7897s, were not configured correctly on installation.
    Issue :
    Flame failure causes recycle.
    At installation Resister JR2 should have been cut, causing unit to lock out at flame failure.
    Page 15 of the Owners manual states there is a 200hr limit...once that 200 hour limit is hit, clipping the resister will cause a hard lockout, code 110.

    So now I have 4 ($800) boiler controllers that will be no good.
    Can they be reset, by someone? Send them in for Refurbishment?
    My Boss has no choice, he will pay the $3200. Seems like a waste.

    There is no way to reset "code 110", it would go away if the resistor is put back in place.
    There is not better place for the working men than the union! 100% UA the only HVAC union!

    After the 200hrs jumper settings are set. Even if you put the jumper back to get it to work you will still have to replace the control due to retries being against code. Unless your company installed them 12 years ago I wouldn’t consider paying for them

    I work for the USPS, and being a Government agency, it is our job to hand out money to contractors. There is ZERO chance we will get the original contractor to pay for the new controllers.

    On the Bright side... Shout out to the Flame Depot. BRAND new controllers for under $350. They do have the capability to refurbish our old controllers... but the cost wasn't worth it when the price of new is $350. The Flame Depot could reset whatever needs resetting. Probably some double secret jumper wire short to kill the memory and reset the 200 hr clock.

    On a side note... Worry not US Taxpayer... the United States Post Office makes PLENTY of money. We put in a Billion dollars a year into the Treasury. Similar to how your Social Security money is being used to float the boat.

    Peace

    So, just wanna be sure I got this straight.

    Boilers ran for 12 years.

    New “boiler inspector” decides they are wrong.

    He clips the jumper, or you clip the jumper at his direction.

    Your boilers fail after 200 hours due to the internal programming of the controller being changed by clipping the jumper.

    The thing I don’t understand is why someone isn’t crawling up the boiler inspector’s boss’s butt about him causing my boilers to fail.

    Am I wrong about him screwing up something that wasn’t broke to begin with?

    You are 100% right! refurbished flame safeguard loses its UL approval and in case of malfunction insurance companies wont pay for damages.

    71CHOPS..
    I didn't fill in all the details...
    The Boiler inspector did not cut the resister. We did..
    We had two boiler controls on hand, so we tried to cut the resister to see what would happen. We wanted to see for ourselves..
    The System for this building has 4 boilers. The building can probably run on one right now. We weren't worried about loosing a boiler.

    MY opinion on the STAMP prices. We raised it because we can...and then large mailers can get a big discount. It's very political. Lobbyists paid for by big mailers probably is the meat of the Matter.

    Trump is making a great point on Amazon too... btw.

    Thanks for the info on refurbished boiler controls, not being viable for insurance.
    Great Info!

    when it comes to commercial equipment, "Hey Y'all watch this!" should be preceded by some in depth research! LOL!!
