Digital input
There are two general digital inputs that can be used by the controller.
The DI7 input can be set to:
• Not used
• Receive night signal. The signal will raise the suction pressure with set offset.
• Register signal from an LP switch. The signal will cause the controller to stop all compressors.
The DI8 input can be set to:
• Not used
• Register signal from an HP switch. The signal will start an override of the fan capacity, and
the compressor capacity will cut.
• Registering a general alarm.
An alarm text can be connected along with a general alarm. This text can be seen in the
display and can be sent to a system device.
The following alarm texts can be selected when DI8 is selected for generel alarm:
Generel alarm, Low pressure, High pressure, High temp, Low temp, Oil level, Oil temp, Liquid
level, Leak, Inverter fault.

Screen saver time
If no buttons have been pushed for a specific period of time, the light in the display will be
minimised.
The light level will be restored upon renewed activity.

If buttons have not been pressed within a specified period of time, the screen will return to
the overview display. Afterwards, the user will have to log on again.
If the time is changed, the new time will apply the next time the user logs in.
If you log out here without waiting for the time-out period to elapse, go to the "Home" dis-
play and hold down the "X" button for 3 seconds.
Access code
The settings in the controller can be protected with three levels of access codes.
Level 1: Only see

The access code is a number between 001 and 999.

cation.
The controller only communicates with system devices that have this baud rate, e.g. AK-SM
850. The value must not be changed
The value must not be changed
