Note: If no button is pressed within 30 seconds, allchanges are recorded and the screen automatically returns to the standardwater temperature display.Note: When the standard mode is selected (sec. 10.3, page 34), the filter/circu-lation pump automatically turns on for a heat call regardless of the pump’sprogrammed start time and duration.11.2 Programming Filter CyclesYour spa comes with four 30-minute filter cycles which activate the filter/circu-lation pump. These cycles are factory programmed to start at 6:00 am, 12:00p.m., 6:00 p.m., and 12:00 a.m. The control system allows you to easily adjusttwo separate aspects of each cycle: 1) the time of day at which it begins; 2) theduration of the cycle.Note: When “Standard” mode is selected (sec. 10.3, page 34) and the filter/circu-lation pump is set to the factory default duration of 24 hours (sec. 11.1), noapparent change of operation will occur. However, when “Economy” mode isselected (sec. 10.3, page 34), the heater activates only during a programmed filtercycle.
