The ICM870 Soft Start is intended for residential, commercial, RV & marine applications. The ICM870 integrates compressor or motor in-rush current over startup time, thus reducing peak current demand on a power supply source by up to 70%. Effectively reducing power draw to the A/C, the ICM870 utilizes a built-in self-learning algorithm to deliver the optimal in-rush current per application. The ICM870 will monitor system health including voltage, current, compressor startup and integrity. Upon a fault condition, it will halt operation and initiate a 4-minute anti-short cycle routine while providing diagnostic fault information by means of an LED indicator.

• Reduces in-rush current/draw necessary at startup by up to 70%
• Prolong the life of the A/C by reducing excessive torque, wear and tear
• Built-in dynamic start delay
• Reduce loud noises, light flickering, and breaker trips
• Built-in self-learning algorithm
• Over-current protection
• Over/under voltage monitoring
• Built-in start capacitor
• LED fault indicators
• Ultrasonic sealed tamper-proof enclosure
• Installation hardware is included

Note:

The ICM870 Series Soft Starts are NOT recommended to be used with air conditioners or heat pumps which have control boards that sense compressor current and perform a lock out for fault conditions.

Any Air Conditioner or Heat Pump which has a Comfort Alert control board or an Emerson Core Sense Module installed are not directly compatible for use with the ICM870 Series Soft Start.

The Emerson CoreSense module can be bypassed when using the ICM870 Series Soft Starts. Unfortunately, the circuit board and kit style Comfort Alert cannot be bypassed and therefore, ICM870 cannot be used.
