EC2-551 for Copeland EazyCool™ condensing unit with Copeland Digital Scroll
compressor
Major parameters for operation
c Application Parameters
c1 Number of compressors
c3 Control mode (network system)
c4 Compressor 1 control mode
c5 Compressor switch logic
Number of compressor to switch on in case of sensor
c6
failure
c1 Number of compressors
This default parameter is set to 2 for two-compressor Copeland EazyCool™ condensing
units.
For single-compressor Copeland Eazy
Scroll™, c1 should be changed to 1.
c 4 Compressor 1 control mode
0 = compressor 1 in standard control loop
1 = compressor 1 act as base load compressor
2 = compress or 1 act as modulating (PWM control for Copeland Digital Scroll™
c ompressor only)
NOTE: For a digital condensing unit c4 should only be fixed on "2"
F Modulating Parameters
F2 Minimum output value
F3 Maximum output value
Minimum & maximum output value could be adjusted
In case of a single compressor Copeland EazyCool™ condensing unit with a Copeland
Digital Scroll compressor, the maximum output could be set below 100% if system
requests less than the maximum capacity. In that case F3 > F2.
Please refer to the controller application guideline (C6.1.3, Part no.: 3125495) supplied
