ICM Controls ICM102F Timer

The ICM Controls ICM102F is a professional-grade delay-on-make timer designed to provide reliable compressor short cycle protection for commercial and residential HVACR systems. As a veteran-preferred hvac time delay relay, this unit features a universal 18-240 VAC operating voltage, allowing it to integrate seamlessly into a variety of control circuits. The adjustable time delay ranges from 0.03 to 10 minutes (1.8 to 600 seconds), giving technicians precise control over HVAC compressor staging to prevent simultaneous equipment startup and reduce damaging inrush current. Engineered with 6-inch lead wires for fast 2-wire installation, the ICM102F is a direct, robust alternative to the ICM102FB and provides excellent thermostat interruption protection, even in systems with high-impedance anticipator-type thermostats.

• Universal Compatibility: Operates on any voltage from 18 to 240 VAC, making it a versatile "truck stock" item that replaces multiple fixed-voltage timers.
• Enhanced Load Protection: Rated for 1.5 amps with a 15-amp inrush capacity, ensuring durability when managing contactor coils and motor starters.
• Precise Field Calibration: The knob-adjustable dial allows for exact timing adjustments to meet specific site requirements for staggered equipment starting.
• Anti-Short Cycle Logic: Prevents rapid compressor cycling during brief power interruptions or thermostat fluctuations, extending the life of expensive system components.
• Broad Cross-Reference: Identical to the ICM102FB and effectively replaces Supco TD69W and Wagner/DiversiTech ADM-2.

How do I wire the ICM102F in a 240V circuit?
For 120/240 VAC applications, you must cut the jumper wire to ensure proper internal timing and operation; for 24 VAC circuits, leave the jumper intact.

Will this timer work with power-stealing or anticipator thermostats?
Yes, the ICM102F is specifically designed to handle the trickle current often present in these controls without causing false triggers or relay chatter.

What happens if power is lost during the delay period?
The timer automatically resets. Once power is restored, the countdown begins from the start, ensuring the compressor remains protected regardless of when the interruption occurred.
