ICM Controls ICM102 Time Delay Relay Control

ICM Controls ICM102 Delay-On-Make Time Delay Relay Control

Protect your compressor from catastrophic short-cycling and manage system staging with the versatile ICM Controls ICM102 Time Delay Relay. This trade-grade, solid-state HVAC control module functions as a universal Delay-On-Make timer. When your thermostat calls for cooling or heating, this relay delays line voltage execution to the contactor or control loop, preventing high-amp equipment from starting simultaneously or restarting too quickly after a brief power interruption.

The ICM Controls ICM102 Control features a highly flexible, universal operating range of 18 to 240 VAC, allowing it to integrate seamlessly into standard 24V residential control circuits or higher voltage commercial configurations.

Technical Specifications:

• Model/Part Number: ICM102 (Directly replaces legacy model ICM102B)
• Timing Function: Delay-on-Make (On-Delay)
• Adjustable Delay Range: 0.03 to 10 Minutes (1.8 to 600 Seconds)
• Input Voltage Compatibility: 18 VAC to 240 VAC (50/60 Hz)
• Maximum Current Load: 1.5 Amps (Steady-state control circuit current)
• Connections: Standard 1/4-inch male quick-connect spade terminals
• Mounting Shape: Compact 2" x 2" square footprint with single-hole mounting center

Key Features & Benefits:

• Universal Voltage Intelligence: Eliminates the need to carry separate, dedicated low-voltage and high-voltage timers. A single module handles everything from 24V furnace transformers up to 240V condensing unit applications.
• Knob-Adjustable Precision: Features a clear, user-adjustable dial interface that lets you fine-tune the delay from a quick 1.8 seconds up to a full 10 minutes for tailored multi-unit staging or safety delay parameters.
• Anticipator Thermostat Compatibility: Specifically engineered to operate flawlessly with legacy anticipator-type thermostats, preventing mechanical chattering or false signals even in the presence of trickle currents.
• Compact, Rugged Construction: Housed in a durable, moisture-resistant epoxy enclosure designed to withstand the high vibration and severe temperature fluctuations found inside outdoor electrical control boxes.

Cross-Reference & Replacement Applications

The ICM102 serves as a direct, drop-in replacement for a massive array of field timers, allowing technicians to consolidate inventory. It is a verified replacement for:

• Legacy Part Numbers: ICM102B.
• OEM Substitutions: Directly replaces the Rheem-Ruud factory P/N 42-108873-01 control module.
• Multi-Industry Functionality: Ideal for compressors, multi-stage air handler staging, ventilation blowers, pumps, and commercial refrigeration setups.
