Pump Safety Protocol
When switching modes (e.g., from Skim to Vacuum), the pump deactivates for 15 seconds to allow valves to rotate safely. This prevents pipe damage from sudden pressure spikes.Safety Timeout
Manual modes (Vacuum, Skim, etc.) automatically reset after 12 hours of continuous operation. The system will then return to its automatic schedule.Pool Operation Control
"This interface provides five manual modes for precise water flow management. Direct hydraulic power exactly where it's needed for peak performance."
- Pump Press to manually activate or deactivate the primary circulation pump for the entire system.
- Vacuum Press to activate deep cleaning. Full pump power is diverted to the bottom vacuum port to effectively clean the bottom surface of the pool.
- Skim Press to start standard filtration. Water is drawn from the surface through skimmers to effectively remove floating debris and maintain water clarity.
- Fill Spa Press to fill the spa, replenishing water levels until the spillway is reached.
- Drain Pool / Spa Press to initiate drainage for water level adjustment or
maintenance.
Caution: Never fully drain the pool without professional consultation to prevent structural damage. - Max Speed Press to override the schedule and run the pump at 100% capacity. Ideal for rapid filtration.
- CANCEL Press to cancel all manual modes, deactivate equipment, and reset valves to return the system to automatic control.

Sensitivity Calibration
To calibrate your system for perfect timing:
1. Observe: During sunset, watch the Sensor Level as it naturally increases.
2. Set ON Point: When the darkness is exactly at your preferred level, note the number
and set your ON Level to match.
Hardware Auto-Calibration:
To reset the sensor's baseline (zero point), press the Auto Control button 5 times
within 6 seconds. The system will capture the current ambient light as the new "zero" reference.
(Note: 99 is complete darkness; 0 is bright daylight).
Control Light
"Sophisticated ambient management. Transform your pool's atmosphere automatically using precision light sensors and intelligent scheduling."
- — DETECTION —
- Sensor Level Displays the current light sensitivity measured by the sensor (0–99).
- — TRIGGER LEVELS —
- ON Level Use the Up and Down buttons to set the sensor sensitivity level that will trigger the lights to turn ON.
- OFF Level Use the Up and Down buttons to set the sensor sensitivity level that will trigger the lights to turn OFF.

- OFF Light after Hrs Use the Up and Down buttons to select how many
hours the lights will remain ON before automatically turning off.
Note: Setting this to 0 or 15 activates "Wait for Dawn" mode. The timer is bypassed, and lights will turn off only when the sun rises (sensor level exceeds the OFF Level). - Seasons Enable Seasonal Adjustment. When active, the system automatically recalculates the ideal lighting duration based on the actual length of the night throughout the year.
- Auto Control Press the button to enable or disable the automatic sensor-based lighting schedule.
Circadian Comfort
The system uses the light sensor to automatically transition the display between your preferred daytime and nighttime intensities. This ensures the screen is readable in the sun and gentle on the eyes at night.

- — SCHEDULING MODES —
- Start Auto Control Press to activate the current countdown and loop configuration.
- ON Fountain after Hrs Set the delay (in hours) before the fountain turns ON.
Ex: If it is 8 AM and you want it ON at 11 AM, set to 3 hrs. - OFF Fountain after Hrs Set the duration (in hours) the fountain stays ON before automatically stopping.
- Loop Enables daily repetition. When active, the system repeats your ON/OFF schedule every 24 hours.
- — AUTOMATION SYNC —
- Auto Control with Sunrise Syncs activation with the break of dawn. If ON after Hrs is 0, it starts exactly at sunrise. Note: Sunrise/Sunset events are calibrated on Screen 9 (OFF Level = Sunrise, ON Level = Sunset).
- OFF Fountain with Light Synchronizes the fountain's shutdown with the pool lighting system.
- — OPERATIONAL RULES —
- • Exclusivity: "Loop" and "OFF after Hrs" are bypassed if Sunrise or Light automation is active. These modes override delay timers as the system switches to direct sensor-driven control.
- • Stability: If the system restarts, you must press Start Auto Control to resume the countdown.
- • Safety: The ON time and OFF time values must never be identical.
Freeze Guard
"Automated cold-weather defense. Protect your investment by ensuring constant water movement and heat distribution when temperatures approach freezing."
