What to do if there is a faulty controller sensor input in Walchem WebMaster?

If you suspect a faulty controller sensor input in your Walchem Accessories, start by going to the Sensor Input Page and running a self-test. If the test passes, the issue likely lies with the sensor or its wiring. If the self-test fails, disconnect the sensor from the circuit board and try the self-test again. If failure persists, consider replacing the circuit board.
