Prestige error code

There are some "blocking" times within the MCBA controller that were designed to prevent short cycling. I have never heard of 15 minutes of re-cycle time though.

    E-11 Prestige error code

    Anyone out there ever receive E-11 error code on any of their Prestige boilers installed. Had a friend that fired his up the other day , this code came up. Service guide said if it continues to happen, after resetting the boiler to replace the MCBA control module. Just curious, if anyone else ever ran into it. Thanks!

    E 11

    I will check with our engineers on this, but my suspiscion is that there was some sort of power issue upon startup: Was the system powered up all at once? All pumps, boiler, everything , creating a possible power drop? Perhaps a touchy ground or something feeding back through the low voltage TT terminals. Has the problem re-surfaced? If so, please let me know.

    error e-11

    Hello Guy,
    I just talked to him a little while ago. He said after he reset the boiler yesterday it's been running OK, but he'd let me know if it happened again. He was going to make sure the wiring looked OK, if the connections were all tight, etc.Hard doing this over the phone. I'm waiting to install my TT Solo 110 when the weather warms. Can't wait!

    I've seen it before

    Hello Guy,

    We've seen this error on start up only. I believe it is attributed to flow problems and a multitude of sensor readings/errors being sent to the control board at same time. This is most likely air in boiler, once system is purged and air is out code never comes back.

    I strongly advise anyone that installs one of these boilers to throw out that manual bleeder they give you for the top of the boiler and install a 1/2 x 1/8 brass bushing and a quality auto air vent. Speaking from experience you will be going home from your install much sooner and not become a manual air vent babysitter on startup.

    good tips Brian

    I install a ball valve up top on that connection. Then offset a bit to keep drips off the boiler and a good air vent. I still use that high flow brass B&G.

    I've had a few startup issues also. Seems you need to wait 15 minutes or so for some errors to clear after a hard reset?

    thanks

    Well, thanks everyone for your input. Hopefully, it was just a fluke. I guess that we'll just have to wait and see.
    If I have any issues with my Prestige on start up, I'll let you guys know.

    A smart thing

    I saw on someone elses job was, in addition to an automatic air bleed on top of the boiler, they installed a tee and a low water cut off control. I know the Prestige has a water pressure switch to protect the boiler, but adding a low water cut off protects the circulators that may run and damage bearings in the event of a water leak. Also a little redundancy on boiler protection is not a bad thing. :) WW

    Agree

    Have made that an SOP for Prestige installs

    jumper

    There are two jumpers on the wiring block that can be used for the LWCO. Breaking one with a LWCO (or flow switch or whatever) will trigger a hard lockout, and the other an auto-resetting lockout.

    Wayne, but multiple redundancy is standard...

    Wayne, my view's a bit different but I think the Prestige already has sufficient redundant protection from low water situations as standard equipment.

    The flow switch will shut the boiler and boiler circ down once the pressure dips below 10psi - long before a LWCO would even kick in. The pressure switch is easily tested and it works well (at least so far).

    If that fails, the boiler's controller will shut things down if the temperature climbs too rapidly. It's part of the MCBA controller logic to track the rate of change in the supply temps. If the temps start to climb too rapidly, the boiler gets shut down, again probably before a LWCO would even switch off the power.

    As most likely the third line of defense, my gut feeling is that the LWCO would be far more likely to false trigger than ever do anything useful. Having it false trigger while away on vacation is not something I'd want the neighbours having to deal with when watching the house.

    I'd rather add another pressure switch and run all the electrics through there than use a LWCO. By the time a LWCO cuts power to a wall hung boiler, I'd already be worried about the HX. I think LWCOs are great for steamers but not a good match for m/c boilers.

    It's amusing to think about Charles Lindberg and his Spirit of St Louis. When asked if twin engines wouldn't have more redundancy, he stated that with two engines his chances of engine failure were exactly double and if either engine failed he wouldn't make it across the Atlantic Ocean.

    BTW, the pressure switch satisfied the LWCO requirements for the inspectors from the city and the gas company. I do have radiation below the level of the boiler so LWCO protection was a requirement.

    LWCO testing

    If you try purging the boiler when it is running with a CH call, you can actually see the LWCO kick in and shut down the boiler. Had this happen to me on a startup recently.

    a LWC on the very top like

    that would be very prone to lockouts if any air were to rise up, and it will.
