Display connection
This is where you define the type of display that is connected to the controller
Off: EKA 164
On: EKA 165. The extended display with LEDs.
Read temperature at sensor "Saux1"
Pressure transmitter's working range
Depending on the pressure, a pressure transmitter with a given working range is
used. This working range must be set in the controller (e.g.: -1 to 12 bar
The values must be set in bar if display in °C has been selected. And in psig, if °F has
been selected.

Use of DI1 input
The digital input can be connected to a contact function, and the contact can now be
used for one of the following functions:
Setting / function:
0: DI input not used
1: Fan alarm when contact cuts out. Alarm "A34" is given.
2: Alarm function when the contact cuts out. Alarm "A28" is given.
There is time delay for the alarm. Setting in "A27".
Use of DI4 input
The digital input can be connected to a contact function, and the contact can now be
used for one of the following functions:
Setting / function:
0: DI input not used
1: Regulation reference P0 displaced when contact is cut in
2: Alarm function when the contact cuts out. Alarm "A31" is given. There is no time
delay.
Use of DI5 input
The digital input can be connected to a contact function, and the contact can now be
used for one of the following functions:
Setting / function:
0: DI input not used
1: Regulation reference Pc displaced when contact is cut in
2: Alarm function when the contact cuts out. Alarm "A32" is given. There is no time
delay
Operating hours
The operating hours for the compressor relays can be read and set in the follow-
ing menus. The read value is multiplied by 1000 to obtain the number of hours (f.ex.
shows 2.1 for 2100 hours). On reaching 99.9 hours the counter stops and must now be
reset to, say, 0. There will be no alarm or error message for counter overflow.
Value for relay number 1 to 4
Value for relay number 5 to 8
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.
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.
Frequency
Set the net frequency.
