can anyone point me to information, besides the owners manual, that would help me in understanding how the aquastat knows when to fire the boiler and when to turn the burner off. contacting honeywell has proved totally useless as the third world call center receiving customer service calls only knows how to tell you they don't support that product to the general public. i know you have to pry up some kind of retainer and move the temperature wheel inside the control, aligning the desired temp. with a pointer in the control. but is that temp the high limit, and the point at which the boiler fires is that temp. minus the differential, or is that temp the point at which the boiler fires and it shuts down when it reaches the set temp plus the differential? all of the above assumes there is a call for heat, as without a call for heat from a thermostat, i realize the boiler just sits there like huge paperweight. any insights to help clear this up for me would be appreciated.
