Adjustment of control direction
The status of the control direction is shown at the LED's at the side (3):
Low: An adjusted minimum set point is controlled by adding an oxydizing agent (e. g. ozone). The
direction of control is upwards. This is the standard mode for controlling the ORP with Ozone in
marine aquariums or for controlling a Nitratereductor with air or dosing pump.
