Circ Pump
Your system is equipped with a circ pump, it maybe configured to work in one of
two different ways:
1.) The circ pump operates continuously (24 hours) with the exception of
turning off for 30 minutes at a time when the water temperature reaches
3 F (1.5°C) above the set temperature (most likely to happen in very
hot climates). Contact your dealer if you would like it to operate this way.
2.) The circ pump stays on continuously, regardless of water temperature.
Note: Standard setting from factory
