ICM® Soft Start Kit

FEATURES

The ICM870 series soft starts ARE compatible with 2-stage HVAC units. If your 2-stage unit has two compressors, you will need two ICM870 units.

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 3 minute anti-short cycle routine while providing diagnostic fault information by means of an LED indicator.

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.
