@ -25,6 +25,8 @@ All functions are controlled by the KY-040 encoder:
* **CTIME**: turn changes the interval in minutes for the fish catching function
* **RTIME**: turn changes speed rise time in seconds (applies to power on, stirrer on, boost on and fish catching)
* **OTIME**: turn changes switch off time in hours (the timer activates immediately, 0 = switch off disabled)
* **Other menu options**:
* **BRGHT**: LCD brightness
