C. Changing the Circulator Settings
The circulator-off delay keeps the C1 output energized
for the set time after a call for heat ends. This helps to
increase the efciency of the system by transferring
more heat into the home instead of letting it sit in the
boiler.
The circulator-on delay holds the C1 output off for the
set time at the start of a call for heat. This helps the
boiler to heat up more quickly and spend less time in the
condensing range (if applicable).
Both circulator delays are selectable from 0 to 4 minutes
and 15 seconds.
