Product Overview

ICM327HN Typical Wiring Diagram
ICM Sensor Probe Mounting
Recommendations
High Efficiency Systems:
• The sensor probe should be mounted up
several bends into the condenser (upper
1/3 as shown at right), to more closely
monitor the condensing temperature
Low Efficiency Systems:
• The sensor may be placed directly on
the liquid line
