ICM Controls ICM102 Timer

The ICM Controls ICM102 is a professional-grade Delay-On-Make Timer designed for precision compressor staging and stagger-starting multiple loads in HVACR systems. This 18-240 VAC delay on make relay provides a universal solution for field replacements, effectively managing power surges by delaying the energizing of components once power is applied to the input. With a wide adjustable timing range from 1.8 to 600 seconds (.03 to 10 minutes), it allows technicians to fine-tune system restarts and avoid rapid short-cycling. Built for rugged performance, it features a 1.5 amp output rating and a 40 mA holding current, making it compatible with modern anticipator-type thermostats. The ICM102 is a compact, 2-wire series hookup control that replaces a vast array of OEM parts, including the 65G70, 024-27664-000, and R68AC0009. Its solid-state design ensures reliable switching in refrigeration and heat pump applications, providing critical compressor protection during transient power events.

Key Benefits

• Universal Voltage Compatibility: Operates seamlessly across a range of 18-240 VAC/VDC for broad application support.
• Adjustable Timing Range: Knob-adjustable delay from 1.8 to 600 seconds provides flexible anti-short cycle protection.
• Direct OEM Replacement: Replaces 65G70, 024-27664-000, ICM100, ICM105, and larger range R68AC0009 units.
• High Inrush Capacity: Features a 15-amp inrush rating and 1.5-amp continuous output for demanding contactor coils.
• Simplified Installation: Standard 2-wire series connection with 2x2 inch footprint fits easily into existing control panels.

Common Questions

How do I wire the ICM102 for a 24V vs 120V circuit?
For standard 24 VAC control circuits, the unit is used as packaged. For higher voltage applications (120/240 VAC), you must cut the onboard jumper wire to ensure proper internal timing and component protection.

Does this timer work with digital thermostats?
Yes, the ICM102 is designed with a 40 mA minimum holding current, which allows it to function correctly with power-stealing and anticipator-type thermostats without causing undesired chattering.

What happens if power is lost during the timing cycle?
The control is a true delay-on-make; if power is interrupted during or after the timing period, the timer resets, and the full delay cycle will begin again once power is restored.
