Condensing Units Equipped

with the EcoNet™ Enabled

2-Stage Control System

EcoNet™ enabled is the next generation of the

Integrated Compressor Control (ICC) and is an

integral part of the EcoNet™ Communication

System with the following features:

Control Description

Dual 7-Segment LED

• Displays status and diagnostic codes see

Status and Diagnostic Description

• Displays diagnostic fault recall see Test ode

Fault Recall)

CAUTION:

UNIT MAY START

SUDDENLY AND WITHOUT WARNING.

Solid red

light indicates a thermostat call for unit operation is

present at the ICC control. ICC control will attempt

to start unit after short cycle timer expires or when

in Active Protection mode will attempt to restart

unit prior to Lockout mode.
