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

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.
