SOL-C12L and SOLC-24L Replacement PCB Boards
We have a stock of PCBs on hand in the unlikely event that an electrical fault develops, to assist keeping your device in good working order.
If we run out of stock, you can use the IRR-PCB-LS PCB board instead, because it is interchangeable with the IRR-PCB-L.
Once the supply of IRR-PCB-L is exhausted, IRR-PCB-LS will become the standard PCB board going forward.
Observe these guidelines to replace the board:Turn the control unit over and remove the 5 screws from the rear lidOpen case lid and place to one sideGrab PCB and slide vertically upRemove the following wires from the PCB: Pump, Water Sensor, Moisture Sensor (if you have one connected), Solar Panel and Battery Pack, dispose of the faulty PCBTake the new PCB and attach the wires into the correct locations.
