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.
ICM870-16A For use with a Compressor Load Amp Rating (RLA) of 9.1-16A Maximum
Please DO NOT assume it is acceptable to upsize the ICM870-9A or ICM870-16A to the largest size (ICM870-32A) when you are unsure of the RLA current or when the current is close to the limit of the ICM870-16A. This practice will defeat the benefit of the Inrush reduction on smaller systems under 16 Amps and defeat the over current safety limit by allowing for a 20A trip point for over current on the ICM870-32A compared to an 11.25A trip point on the ICM870-16A.
Reduces in-rush current/draw necessary at startup by up to 70% which prolongs the life of the A/C by reducing excessive torque, wear and tear.
Reduce loud noises, light flickering, and breaker trips. Built-in dynamic start delay. Built-in self-learning algorithm. Built-in start capacitor.
Over-current protection. Over/under voltage monitoring. LED fault indicators. Ultrasonic sealed tamper-proof enclosure. Installation hardware is included.
