Display of suction pressure and condensing pressure
One to four separate displays can be connected to the controller.
Connection is accomplished by means of wires with plug
connections. The display may be placed in a control box front, for
example.
When a display is connected, it will show the value for what is indi-
cated in the setup. It can be:
compressors regulation sensor
P0 i temperature
P0 i bar-absolute
Pctrl bar-absolute
S4
Ss
Sd
Condensors regulation sensor
Tc
Pc bar-absolute
S7
Sgc
Shp
Pgc bar-absolute
Prec bar-absolute
Stw8
Shr8
Speed Compressor
Display Primary readout *
A Regulation sensor suction
pressure
B Regulation sensor con-
denser
C SS
D SD
* The primary reading can be changed to other measurements, if required.
When (on plug A) a display with control buttons is chosen, a sim-
ple operation via a menu system can be performed in addition to
the display of suction pressure and condensing pressure:
No. Function
o57 Capacity settings for condenser
0: MAN, 1: OFF, 2: AUTO
o59 Capacity setting for suction group
0: MAN, 1: OFF, 2: AUTO
h15 High pressure. Setting of Pgc minimum
h16 High pressure. Setting of HP-control mode: Automatic /
manual
h17 High pressure. Manuel mode. Setting of valves opening
degree
h18 Heat recovery. Reference for Shr8-temperature
h19 Heat recovery. Setting of heat recovery control mode:
Automatic / off
o30 Refrigerant setting
058 Manual setting of condenser capacity
o60 Manual setting of suction capacity
o62 Select of predefined configuration
This setting will give a selection of predefined combina-
tions which at the same time establish the connections
points.. At the end of the manual an overview of options
and connection points is shown. After the configuration
of this function the controller will shut down and restart
o93 Lock of configuration
It is only possible to select a predefined configuration or
change refrigerant when the configuration lock is open.
0 = Configuration open
1 = Configuration locked

output "B" etc.)
If you want to see one of the values for what is given under "func-
tion" you should use the buttons in the following way:
1. Press on the upper button until a parameter is shown
2.Press on the upper or lower button and find the parameter you
want to read
3. Press on the middle button until the value of the parameter is
displayed.
After a short time, the display will return automatically to the
"Read out display".
