6 Frequently Asked Questions How does the IntelliLevel™ Automatic Water Leveling System work on a suction line that is connected to the pump? The IntelliLevel system controller incorporates a pressure sensor that detects operation of the pump at different speeds. When the pump is not functioning, the IntelliLevel controller opens a small micro-vent for a brief duration of time to allow the water level in the pipe to become equal to that of the pool. The IntelliLevel controller is able to shut the vent within a fraction of a second if the pump operation is detected when the micro-vent is open. How does the IntelliLevel controller identify when the water is low? The IntelliLevel controller uses pressure sensors to continuously measure the pressure in the pipe (when the pump is not running). If the pressure level changes significantly, a micro vent is opened internally to allow the water level in the pipe to become equal to the level of the pool or spa. At this time ultrasonic sensors are used to accurately determine the difference in water level compared to the water level of the set point. If water level is measured to be a ¼ inch or more below the Target Level, the IntelliLevel controller enables the Fill Control Valve. How does the IntelliLevel controller measure the amount of water filled? While filling, the pressure sensor is used again to measure the change of pressure in the pipe and after venting, the ultrasonic sensors are used to measure the water height. The IntelliLevel controller does not have any jumpers to configure time of fill. How does it work with different pool sizes? The IntelliLevel controller monitors the amount of water added, and saves a running average of the measured fill time to recognize any abnormalities in filling. For example, water line being disabled, etc. Why can't I set the water level while the pump is running? Turn the pump OFF for a minimum of one hour a day to allow the IntelliLevel controller to operate. The IntelliLevel controller will not measure or fill the pool when the pump is running. If you run the pump 24/7, the IntelliLevel controller will not measure the water height. IntelliLevel Automatic Water Leveling System Installation and User's Guide
