I am thinking of installing a Honeywell L7224U electronic boiler control on my
Weil McLain gold series boiler. I do not make hot water with my boiler, and as
so, it does not run when the house is not calling for heat. It has a single
aquastat L8148A on it now that does not have a low limit control to keep the
boiler warm. According to my oil service company tech, this cooling off causes
moisture buildup, and because of the moisture, causes any fluffy carbon build up
in the boiler to solidify, and clog up the unit, which has happened a few times
already. The L7224U control box has a programmable low limit that you can set as
low as 110 degrees, just to keep the boiler warm when the house is not calling
for heat in the summer. My service guy says that this should keep the carbon
from solidifying and plugging up the boiler. I have read thru the instructions,
and there is only 1 thing that I question. If the power goes out, does the unit
lose all of its programming, or does it retain it all during a power outage ???
I can't find anyone who has installed one of these yet and has any experience
with them.

        Then sell it. that's all it's good for. That's all boilers
do. They take cold water and turn it into hot water.

        Apparently he thinks you're an idiot.

        Yes. For sure. Every time. Absolutely. Uh huh.

        Oh ? What about your 'oil service company tech ' ???

        Apparently you think WE'RE idiots enough to believe your
bullshit story.

It has to have something to retain its settings, but why get such a fancy,
expensive control. Just wire an aquastat into the water jacket that closes
at 110 degrees or whatever you like and be sure to wire it into the burner
circuit only, so it doesn't start any circulators
