The ICM203 is a universal Delay-On-Break (DOB) timer designed to protect HVAC and refrigeration compressors from rapid short cycling. When power is removed, the timer prevents the compressor from restarting until the adjustable delay period has expired, helping extend compressor life and improve system reliability. It features universal voltage operation, a simple 2-wire installation, and an adjustable delay from 1.8 to 600 seconds (0.03–10 minutes).
