Notes<br />
a. Boiler Pump is “<strong>On</strong>” when the Boiler Pump is set to “<strong>On</strong> Always” or the boiler is lead boiler and Boiler Pump is set to “<strong>On</strong> Lead”.<br />
b. Boiler Pump is "<strong>On</strong>" when the Boiler Pump is set to "<strong>On</strong> Always" and WWSD is set to "WWSD of System Pump" or “Off”.<br />
c. System Pump is "<strong>On</strong>" when the System Pump is set to “yes” and WWSD is set to either "WWSD of Boiler" or "Off".<br />
d. Boiler pump is "<strong>On</strong>" during Prepurge and Post Purge when Boiler Pump is set to "Purge" or boiler is lead & Boiler Pump is set to “<strong>On</strong> Lead”.<br />
e. Combustion Air Damper Spare Output is maintained “<strong>On</strong>” for 2 minutes after the Call For Heat is removed.<br />
f. Modulation rate is held at purge % when low fire input is not provided.
