Your skills are better than mine. What I found -using a couple different hard wired resets, was call for hotter boiler temp
was sloooow-like cold house slow. What ever the program was, it just could not respond appropriately to these old houses. I adjusted again and again, could never get it. Got close once or twice, then a windy day, bam, cold house. So, I asked a couple plumber
friends and they laughed-said on an older house, not going to work. A buddy has an oil company, does installs etc. He won't use
them at all!Not to sell more oil, but to keep the cold house calls to a minimum. So, seasonally, I just pop down and change the boiler temp manually. 135 summer,180 winter, 155 spring and fall. Saves some cash,but not as good as a well matched auto reset.
