autopilot took a lightning hit. i replaced it with a new DIG 220. Then the pump went out so I replaced it with a new hayward 1hp pump/motor. everything works but I can't get the new DIG 220 programmed. How do I set up the salt level and water temp. it keeps saying check flow, purifier off. The cell was not replaced due to it being in such good shape.. ie no scale what so ever. the cell is a SC 36;
