ICM Controls ICM206 Relay

The ICM Controls ICM206 is a professional-grade 18-30 VAC delay-on-break timer designed to prevent compressor short cycling by maintaining a specific lockout time after power interruption. This 4-terminal adjustable time delay relay features a broad timing range of 0.03 to 10 minutes (1.8 to 600 seconds), providing precise control over HVAC system cycles. Engineered for high-demand environments, the solid-state ICM206 serves as a high-reliability low voltage timer to protect critical system components from rapid restarts during thermostat oscillations or power flickers. As a versatile HVAC replacement part, it features an industry-standard 2" x 2" footprint for easy field installation. It functions as a direct drop-in replacement for the ICM205 and various legacy models including 7035, F534, and 8201-050BX. This component is essential for modern air conditioning and refrigeration service calls where short cycle protection is required to ensure long-term compressor reliability and electrical stability.

Key Technical Benefits

• Adjustable Timing Range: Field-adjustable knob allows for timing between 1.8 and 600 seconds to meet specific manufacturer anti-short cycle requirements.
• Direct Application Fit: Direct replacement for ICM205, 8201-050BX, 7035, F534, FF534, and F530, simplifying inventory for service trucks.
• Simplified Wiring: 4-terminal configuration integrates easily into 24V control circuits, serving as a reliable compressor lockout timer.
• Thermal Protection: Solid-state construction eliminates moving parts and contact pitting, common failure points in mechanical relays.
• Universal Compatibility: Works with most 24V HVAC transformation systems and digital or mechanical thermostats.

Common Technical Questions

How does a delay-on-break timer protect the compressor?
The ICM206 prevents the compressor from restarting immediately after it shuts off or loses power. By enforcing a mandatory delay, it allows system pressures to equalize, preventing high-amp draws and mechanical stress during startup.

Is the ICM206 compatible with 120V or 240V systems?
No, this specific model is designed for 18-30 VAC control circuits. Attempting to apply line voltage to this low voltage timer will result in immediate component failure.

What happens if the power flickers during the delay period?
The timer automatically resets. If power is interrupted at any point during the timing cycle, the adjustable time delay relay restarts the full timing sequence from zero to ensure maximum protection.
