Condensing Unit Controller EC2-5X1
2 Product
Description
The EC2-5X1 electronic condensing unit controller has been specially developed for the
Copeland EazyCool™ condensing unit range.
The EC2-5X1 electronic condensing unit controller is mounted as standard in the
following Copeland EazyCool™ condensing units:
Copeland EazyCool™ stand alone two compressor condensing units:
EC2-
511
Copeland EazyCool™ stand alone Digital Scroll™ condensing units:
EC2-
551
o
Single compressor condensing unit
o
Two compressor condensing unit
Copeland EazyCool™ condensing units for refrigeration networks:
EC2-
551
The electronic controller enables:
1.
Compressor modulation and/or staging based on suction pressure
2.
LON (Local Operating Network) communication if connected to a PC with a
LON interface installed, monitoring of operation parameters (pressures,
temperatures as well as alarm states) becomes possible.
3.
Fan speed control if an Alco Controls FSP150 fan speed driver is installed
(available as a factory fitted option).

The next pages contain a description of these controllers and the parameters that can be
changed. The controller has been pre-programmed with a number of parameter values
that are most likely correct. Individual installation requirements however may make it
necessary to alter parameter settings (e.g. suction pressure settings for compressor
capacity staging, control dead band, refrigerant parameter).
High Voltage
Attention: Before carrying out work on the condensing unit, make sure that main power
supply to the unit has been switched off!
