Thermostat shuts down before radiators are completely hot.
I have a Burnham MegaSteam boiler and a Honeywell CT8602 thermostsat. I have the thermostat set to 69 degrees around the clock, 7 days a week. The problem is that when the thermostat calls for heat the steam comes up but the thermostat shuts down before the radiators are completely hot. The room temperature display on the thermostat stays at 69 degrees all the time. The radiators furthest from the boiler get less hot. Any suggestions?
