for setting the Automatic timer program).
• Select the parameter value by turning the rotary knob to the left or to the right until the desired value appears in the display.
• Accept the selection by pressing the rotary knob.
This manual will give you an overview of the method of parameter modification in the THETA 23R Control.
A detailed description is given in the operating manual of the control.
