Mode 1- (Aux1, Aux2, Aux3) - The time switch is a 3-circuit switch with all three switches controlling auxiliary devices. Mode 2- (Pump High, Pump Low, Aux3) - The time switch is a 2-circuit switch with the 1st and 2nd switch controlling a 2-speed pump. The 3rd switch is controlling any auxiliary device. All protection associated with a two speed pump is preprogrammed into this mode. Mode 3- (Pump, Aux2, Cleaner Pump) - The time switch is a 3-circuit switch with the 1st switch controlling a single speed pump, the 2nd switch controls any auxiliary device, and the 3rd switch operates a booster/cleaner pump. All timing and protection associated with a filter pump/cleaner pump combination is preprogrammed into this mode. Mode 4- (Pump High, Pump Low, Cleaner Pump) - The time switch is a 2-circuit switch with the 1st and 2nd switch controlling a 2-speed pump. The 3rd switch is controlling a booster/cleaner pump. All protection associated with a 2-speed pump and booster/cleaner pump combination is preprogrammed into this mode. Mode 5- (Pump L1, Pump L2, Aux3) - The time switch is 2-circuit switch with the 1st and 2nd switch controlling a 240V pump, where both L1 and L2 are required to be disconnected when the pump is turned OFF. The 3rd switch is controlling any auxiliary device.
