The error display resets itself approx. 10s after the error has been cleared or can
be reset by briefly removing the 24V DC. The desired wind swell values are entered
through an 8-part switch on the front of the device. Please note that for security reasons
an increased wind swell value will only be accepted after briefly removing the power
supply. A lower wind swell value will be accepted immediately.
