Refrigerant setting
(only if "r12" = 0)
Before refrigeration is started, the refrigerant must be defined. You may choose be-
tween the following refrigerants
2=R22. 3=R134a. 13=User defined. 17=R507. 19=R404A. 20=R407C. 21=R407A.
37=R407F.
Warning: Wrong selection of refrigerant may cause damage to the compressor.
Other refrigerants: Here Setting 13 is selected and then three factors -Ref.Fac a1, a2
and a3 - via AKM must be set.

Digital input signal - D2
The controller has a digital input 2 which can be used for one of the following func-
tions:
0: The input is not used.
1: Status display from an external safety function (short-circuited =ok for compressor
operation)
2: Main switch. Regulation is carried out when the input is short-circuited, and regula-
tion is stopped when the input is put in pos. OFF.
3: Night operation. When the input is short-circuited, there will be regulation for night
operation.
4: Separate alarm function. Alarm will be given when the input is short-circuited.
5: Separate alarm function. Alarm will be given when the input is opened.
6: Input status, on or off. (DI2 status can be tracked via data communication)
7: Alarm from the compressor's external speed control.

Select the type of condensing unit.
Factory set.
After the first setting, the value is 'locked' and can only be changed once the control-
ler has been reset to its factory setting.
When entering the refrigerant setting, the controller will ensure that the 'Unit type'
and refrigerant are compatible.

Save as factory setting
With this setting you save the controller’s actual settings as a new basic setting (the
earlier factory settings are overwritten).

Period time for heating element in crankcase
Within this period the controller will itself calculate an OFF and ON period.
The time is entered in seconds.

Difference for the heating elements 100% ON point
The difference applies to a number of degrees below the 'Tamb minus Ts = 0 K' value.

Operating time for condensing unit
The condensing unit's operating time can be read out here. The read-out value must
be multiplied by 1,000 in order to obtain the correct value.
(The displayed value can be adjusted if required)
