Light-emitting diodes (LED) on front panel
All 4 light-emitting diodes will ash when there is an error in the
regulation.
In this situation you can upload the error code on the display and
cancel the alarm by giving the uppermost button a brief push.
The controller can give the following messages:
E1
Error message
Fault in controller
E15
Cut-out S2 sensor
E16 Short circuited S2 sensor
E17 Cut-out S3 sensor
E18
Short circuited S3 sensor
E20 Fault on signal from Pc
E39 Fault on signal from P0
A11
Alarm message
No refrigerant has been selected
A43 Step motor fault. Output or phase
A45 Regulation stopped. Main switch r12 = o
Display
The values will be shown with three digits.
Temperature are shown in °C and pressure in bar.
Operation
Menu survey
The buttons
When you want to change a setting, the two buttons will give you
a higher or lower value depending on the button you are push-
ing. But before you change the value, you must have access to the
menu. You obtain this by pushing the upper button for a couple
of seconds - you will then enter the column with parameter codes.
Find the parameter code you want to change and push the two
buttons simultaneously. When you have changed the value, save
the new value by once more pushing the two buttons simultane-
ously.

Examples of operations
Set of a menu
1. Push the upper button until a parameter is shown
2. Push one of the buttons and nd the parameter you want to
change
3. Push both buttons simultaneously until the parameter value is
shown
4. Push one of the buttons and select the new value
5. Push both buttons again to conclude the setting

Normal display
Displays either the valve's current opening degree or the current superheat value.
(Can be set in o17)
Briey pushing the bottom button will display one of the two readings.
Briey pushing both buttons will display the superheat reference (u22).

*) This setting will only be possible if a data communication module has been installed in the
controller.
**) The display on the controller can show 3 digits only, but the setting value has 4 digits. Only the
3 most important will be shown. It means fx. 250 will give a setting of 2500.
