KE2 Compressor Sequencer OEM
Quick Start Guide
This reference should remain on site with the installed KE2 Compressor Sequencer
Product Summary:
Pg. 1
The KE2 Compressor Sequencer OEM allows control of up to 8 stages of loading for a single suc-
tion group, or up to 10 stages of loading (5 per suction group) for dual suction groups.
Pg. 1
Pg. 2
For dual suction groups, the controller is applicable to both racks with a shared common dis-
charge, or independent discharge lines. Suction pressure can be controlled to either a fixed
setpoint, or a floating suction pressure for maximum efficiency.
Pg. 3
Each stage of loading can be set to: fixed speed compressor, variable speed compressor

a Master Liquid Line Solenoid, or as a Hot Gas Defrost Relay.
Communication:
As is standard with many other KE2 Therm controllers, the KE2 Compressor Sequencer OEM has
the simplest and easiest communication platform in the industry. The controller uses standard
communication protocols and cables; no extra software is necessary, only an Ethernet connec-
tion to the controller. E-mail and/or text alerts can be sent out right from the controller. Com-
plete remote access is available during startup with one simple button press and an Internet
connection.
