I hate short cycle burns.. I got a little box to install on top of the Aquastat, and it helped a lot.
I very rarely get a short cycle anymore.
Residential Boiler Controls | Beckett HeatManager
It's the gadget on top.
Nowadays, this boiler is my back-up system and I've started using
the free-flow valve and the timer to keep hot water circulating on these really cold nights.
The circulator pumps don't come on at all..
We have baseboard and convection does the job.
The timer is kinda crude, but it works okay for my needs..
