The three push buttons Manual, 0 and Auto are used to select the running mode of the ventilation
unit. The lowest line on the display indicates the actual running mode with the symbol , which
points to one of the three push buttons.
By activating Manual the ventilation unit is switched to run in manual mode, that is user defined
(See chapter 2.5 Setting of manual running mode). The ventilation unit will now run according to
the manual settings for the next 2 hours (factory setting 2 hours - maximum 24 hours) and, once this
time has elapsed it will return back to the settings in the week program.
This function is very useful if, for example, you want to start or stop the ventilation unit in
unoccupied periods, without making changes in the week program.
By activating 0 the ventilation unit stops until Auto or Manual gets activated. This function can be
useful if you want to stop the ventilation unit on short working days.
By activating Auto the ventilation unit follows a pre-defined week program, which is user defined
(See chapter 2.6 Setting a week program).
The following push buttons are used to select menu and change/save settings on the display.
By pressing or it is possible to pick a specified menu line. The highlighted menu line shows
the actual sub menu.
When you want to select a sub menu you have to press Enter.
To increase or decrease a set point value push the buttons + or –. Press Enter to save the corrected
set point.
Moving to a menu that is above the actual menu press until the required menu appears.
