Panel implements the control functions which are monitored by an electronic water level sensors as follows: Quick Fill Operation Energies 24 volt solenoid actuated water supply valve required to sustain optimum operating water levels. Safe-Off Operation Shuts down all in-pool electrical functions during low or unsafe water level situations. Maxi Level Control Allows greater water level differentials between upper and lower operating levels. Utilizes two sensors instead of one in special situations; for example, wavy pools or multi-level applications which may temporarily incur unusual water displacements. This sensor may also be utilized to signal high water or flood conditions on indoor and upper level installations.
