i replaced my aaqualogic logic display ps 8 board and not all functions work the heater, spa to pool , cleaner all work but the lights and to turn actual filter on/ off wont work the display says on or off the the actual filter stays on whats up?
The display unit has a wire that connects to the main board. Remove the connector and plug it back in to make sure the connection is solid. Also check the wires that connect to the plastic connector to make sure there isn't one that is loose.
So what happened to the original display unit?
Were these function operational before the swap?
Was the replacement a used display unit or a new one?
