ICM Controls ICM866U-LF Hard Start

The ICM Controls ICM866U-LF Hard Start Kit is a high-performance, universal hard start kit engineered for 1/12 to 5 HP compressor applications. Built for 115V and 230V motors, it utilizes patented differential voltage sensing technology to monitor auxiliary voltage with professional-grade precision. Unlike standard kits, the high-powered relay output enables multi-voltage operation, ensuring the 145-175 ?F start capacitor engages only when necessary and disengages exactly at 80% motor speed. This prevents overlapping stays that damage windings and provides a significant boost in starting torque, essential for systems experiencing low-voltage stalls or long line sets. This veteran technician?s choice is a direct replacement for ICM805, ICM866U, and ICM810, effectively reducing stock requirements for service trucks. With a two-wire installation and self-adjusting circuitry, it eliminates the need for factory presets, allowing for rapid deployment in residential and light commercial HVACR maintenance.

Key Benefits for Contractors:

• Universal HVAC Compatibility: Supports a wide range of single-phase PSC compressors from 1/12 to 5 HP, covering most residential and light commercial units.
• Advanced Voltage Sensing: The differential voltage sensing ensures accurate engagement regardless of ambient temperature or line fluctuations.
• Optimized Starting Torque: Provides the necessary electrical boost to overcome mechanical resistance, particularly in older systems or those with hard-starting compressors.
• Simplified Two-Wire Setup: Streamlines the installation process and reduces the risk of miswires on busy service calls.
• Self-Adjusting Precision: Automatically adapts to the specific electrical characteristics of the motor without manual range setting.

Common Questions:

Can I use this on 115V and 230V systems?
Yes, the multi-voltage operation allows for seamless use on both 115V and 230V AC motors, making it a truly universal solution for your service inventory.

What is the retry time for this unit?
The ICM866U-LF features an instant recycle capability with a retry time within 90 seconds, ensuring the system can attempt a restart quickly after a power interruption.

Does it replace the SUPCO SPP6?
Yes, this hard start kit with relay is a versatile replacement for many common industry models, including the SUPCO SPP series and 5-2-1 kits, provided the HP rating falls within the 1/12 to 5 HP range.
