Configuration settings (compressor and fan definitions, coupling mode and refrigerant) can only take place when regulation is stopped.
Warning ! Direct start of compressors *
To prevent compressor breakdown parameter c01 and c07 should be set according to suppliers requirements or in general :
Hermetic Compressors c07 min. 5 minutes
Semihermetic Compressors c07 min. 8 minutes and c01 min. 2 to 5 minutes ( Motor from 5 to 15 KW )
* ) Direct activating of solenoid valves does not require settings different from factory (0)
Refrigerant setting
Before refrigeration is started, the refrigeration must be defined. You may choose
between the following refrigerants:
1=R12. 2=R22. 3=R134a. 4=R502. 5=R717. 6=R13. 7=R13b1. 8=R23. 9=R500.
10=R503. 11=R114. 12=R142b. 13=User defined. 14=R32. 15=R227. 16=R401A.
17=R507. 18=R402A. 19=R404A. 20=R407C. 21=R407A. 22=R407B. 23=R410A.
24=R170. 25=R290. 26=R600. 27=R600a. 28=R744. 29=R1270. 30=R417A.
31=R422A, 32=R413A. 33=R422D. 34=R427A. 35=R438A. 36=XP10. 37=R407F.
Warning: Wrong selection of refrigerant may cause damage to the compressor.
Other refrigerants: Select setting 13 here, and subsequently three factors have to be
set – fac1, fac2 and fac3 – via AKM.

Manual control (stopped regulation only)
From this menu the relays can be cut in and out manually.
0
gives no override, but a
number between 1 and 10 will cut in a belonging relay. 1 will cut in relay number 1, 2
relay 2, etc.
11-18 will produce voltage on the analog output. In this way the relays on the exter-
nal relay module can be activated. Setting
11
will give a voltage of 1.25 V, setting 12
will give 2.5 V, etc.
o18 Manual control
Frequency
Set the net frequency.
o12 50 / 60 Hz
(50=0, 60=1)
Address
If the controller is built into a network with data communication, it must have an
address, and the master gateway of the data communication must then know this
address.
These settings can only be made when a data communication module has been
mounted in the controller and the installation of the data communication cable has
been completed.
This installation is mentioned in a separate document “RC8AC”.
Following installation of a data com-
munication module, the controller can
be operated on a par with the other
controllers in ADAP-KOOL® refrigera-
tion controls.
The address is set between 1 and 240 (gateway determined) o03
The address is sent to the gateway when the menu is set in pos. ON o04
Access code
If the settings in the controller are to be protected by a numerical code, you can set a
numerical value between 0 and 100. If not, you can cancel the function with setting
OFF.

Special settings
Outputs DO9 and DO10 are normally used for the ”AKD start/stop” function and for
the alarm function, but they may be redefined in special cases.
DO9 function:
0: AKD Start/stop
1: Inject-on function (see drawing below)
2: Boost ready function (see drawing below)
3: Fan relay
o75 DO9 function
DO10 function:
0: Alarm relay
1: Fan relay
o76 DO10 function
