This is Levelor Electronic Water Fill System and is made by Jandy Corporation. It is the best way to keep your swimming pool/spa properly filled with water at the precise level of optimization. The biggest problem with any pool is that the water evaporates in the heat of summer and if the water gets too low, the filter system will not work properly. Customers much keep an eye on water levels every day so the pool suction will not fail. The Levelor System simply allows the flow of fresh water into the pool/spa when the computer notices that water level has dropped. When the water level is at the proper height, the system shuts off. Keeping the water even at all times can be accomplished using the Levelor System and we have been installing the electrical to these for decades. It is not terribly expensive either, and a must for all swimming pool owners.
