ICM206 RELAY, DELAY ON BREAK 10min ADJ.

The ICM206 is a delay-on-break timer designed to protect HVAC systems—especially compressors—from short cycling and low-voltage starts. It’s a compact, adjustable relay module that introduces a delay (3 to 10 minutes) after the system shuts off before allowing it to restart.

Key Features:

  • Function: Anti-short cycle timer (delay on break)

  • Adjustable Delay: 3 to 10 minutes

  • Voltage: 18–30 VAC

  • Amperage: 1.5A (15A inrush)

  • Protection:

    • Prevents scroll compressor reversal

    • Brownout protection

    • Eliminates relay chatter from thermostat bounce

  • Compatibility: Works with anticipator-type thermostats

  • Response Time: 16 milliseconds

  • Mounting: Compact 2" × 2" footprint

It’s UL-recognized and often used in systems where compressor protection is critical—like older units or those with frequent cycling issues
