14 C6.1.7/0609-1110/E
/1 Value to show on display
0 = Compressors and fans states (controller 1 = Compressor(s), and controller 2 = Fan(s))
1 = Suction pressure (bar(g))
2 = Saturation temperature from suction pressure (°C)
3 = Condensing pressure (bar(g))
4 = Saturation temperature from condensing pressure (°C)
5 = Digital Scroll™ capacity (%)
6 = Fan speed (%)
7 = Digital Scroll™ discharge temperature (°C)
3.6.2 Parameter modification
 Press or to show the code of the parameter that has to be changed
 Press SEL to display the selected parameter value
 Press or to increase or decrease the value
 Press SEL to temporarily confirm the new value and display its code
Repeat the procedure from the beginning "press or to show..." to modify another parameter,
etc.
To exit modifying the parameters with the new values:
 Press PRG to confirm the new values and exit the parameter modification procedure
To exit without modifying any parameter:
 Do not press any button for at least 60 seconds (TIME OUT)
3.6.3 Important parameters on EC2-552 to configure according to unit model
Major parameters for operation of Copeland Scroll Digital™ Receiver unit HLR with Digital
Scroll™ compressor:
Parameter
c Application Parameters Min Max Unit Def
c1 Number of compressors 1 2 - 2
c4 Compressor 1 control mode 0 2 flag 2
c5 Compressor switch logic 0 1 flag 1
c6
Number of compressor to switch on in case of sensor
failure
0 2 - 0
EC2-552
Table 8
c1 Number of compressors
This default parameter is set to 2 for two-compressor units
For single-compressor receiver units with Digital Scroll™, c1 should be changed to 1
c4 Compressor 1 control mode
0 = compressor 1 in standard control loop
1 = compressor 1 act as base load compressor
2 = compressor 1 act as modulating (PWM control for Digital Scroll™ compressor only)
NOTE: For a digital unit c4 should only be fixed on "2".
