2.  Operation and function

2.1  Pushbuttons for adjustment

The controller is operated by the 3 keys below the display. 

To enter the configuration mode toggle through the display 
parameters  by  pressing  and  releasing  key  1  until  this  no 
longer causes the display to change. At this point press and 
hold key 1 until the configuration parameters are displayed 
(about 5 seconds), then quickly release the key to avoid tog-
gling to the end of the parameter list. The first parameter in 
the list is DT O. To change the setting of a given parameter, 
follow the steps below.

1. Toggle to the parameter using keys 1 and/or 2. The 
abbreviation for the parameter is displayed on the right 
side of the screen, with the setting directly below, and the 
set icon solid (not blinking) on the extreme right.
2. Press key 3. The set icon begins blinking signifying that 
the parameter may now be adjusted.
3. Quickly use keys 1 and/or 2 to change the setting to 
that which is required.
4. Press key 3 again. The set icon stops blinking signifying 
that the new value has been stored.
