and shall operate under its onboard controls to maintain its outlet set point (180°F).
H. Boiler sequencing: As the hot water supply temperature falls below set point (5°F below
set point for 5 minutes) OR if the return water temperature falls below set point (142°F) as
sensed by the primary loop return line, the second boiler (lag boiler, B-1) shall be enabled,
where its primary pump shall be started just prior to the boiler firing and shall operate
under its onboard controls to maintain set point (180°F). Each boiler will utilize its
onboard controls to maintain each boiler’s set point, where both are set to 180°F. The
