The call for heat is typically made by a room thermostat.
Select an appropriate boiler water temperature (based upon advice from your heating contractor).
The factory default setting is between 104° F and 167° F (40° C and 75° C).
An elevated setting between 104° F and 212° F (40° C and 100° C) is possible if an adjustment has been made
