Description
32A Soft Starter
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.
*New feature: Upon installation and every start cycle, the ICM870 soft start will initiate a routine 4-minute start delay indicated by a rapid flashing Red LED indicator light. Power on the A/C unit and wait 4-minutes for the delay routine to conclude. This should follow with a successful call from the thermostat, A/C startup and the LED indicator light to change from Red to Green. This feature has been added as a benefit to protect the compressor and ICM870 from rapid short cycling during startup.
