boiler not heating radiators, bad vapostat settings?
Thermostat is calling for heat, boiler turns on, but it shuts off after 30 seconds. It does turn on intermittently for short periods, but not enough to heat the building.
I have called the pros on multiple occasions but I have not been successful with getting a running system and trying to understand things myself at this point.
My vaporstat (diff subtractive) main is set for 1 PSI with a diff of 12 OZ. Picture is below. Is this a reasonable setting? The main setting seems to be too low to me. What would be good settings to start with? I think I want to raise the main to 2 PSI
