Fault code CH04 indicates that the float switch of the fan coil has risen.

On fan coils without a drain pump it indicates that the jumper (blue plug with 30mm of blue wire) in terminal CN FLOAT is missing.

If the fan coil is running and the float rises it will take 3 ½ minutes for the fault to show on the controller, this is to give the unit time to pump excess water away. Once the float falls, (or the jumper is put back into the board)

it will not be possible to clear the fault for 40 seconds. It is considered good practice to reset the power to clear this fault code.
