All setup menu items follow the same adjustment procedure. Menu items that can be adjusted include:

[MODE] OPERATING MODES

Operating modes affect heating and filtration behaviour. The choices are:

• NORM: Normal heating & filtration.
• AWAY: Heating disabled. Filtration reduced to 1 hour per day.
• WEEK: Mon-Thu (works like AWAY mode); Fri-Sun (works like NORM mode).

[FILT] DAILY FILTRATION TIME

Adjust the hours of filtration per day. Filtration limits differ for pump types:

• Circ Pump (2A or less): 1-24 hrs
• Jet Pump (2spd or 1spd): 1-8 hrs

Note: Once P.SAV mode is selected, the begin and end times of the PEAK power tariffs must be set so the control knows NOT to operate during those peak hours.

[F.CYC] FILTRATION CYCLES

This setting defines how often filtration cycles occur. Filtration can be set to run every 1, 2, 3, 4, 6, 8, 12, or 24 hours.

[SNZE] SLEEP TIMERS

• 1.SNZ: Sleep Timer #1
• 2.SNZ: Sleep Timer #2
• R.SET: Reset timers to default
• EXIT: Exit sleep timer menu

Only one sleep timer needs to be set, however, two timers are provided to facilitate different sleep settings on different days. Each sleep timer setting consists of a week day setting, start time, and stop time. Use the [UP Button], [DOWN Button], and [OK Button] to adjust and confirm each setting.

[P.SAV] POWER SAVE (off peak)

Reduce operating costs by limiting filtration and heating to occur during cheaper off-peak power periods. There are three P.SAV modes:

• OFF: P.SAV disabled.
• LOW: Off-peak filtration only.
