Boost Time
Boost Time temporarily overrides the Outdoor Reset Curve, bringing the boiler up to the maximum
setpoint to satisfy a thermostat call in less time. For example, if 6 minutes is selected, and there has been a
thermostat call for 6 minutes, the boiler will override the Outdoor Reset Curve and boost to the maximum
setpoint until the call for heat is satised. The setpoint will stay at max for 6 minutes from the time the
thermostat opens. After the 6 minutes have elapsed the setpoint will return to the Outdoor Reset Curve.
Factory Default: 0 min (Range: 0-762 min in increments of 6 minutes.)
