Description
The ICM870-32A reduces the surge of power when a compressor or motor starts, cutting the peak power demand by up to 70%. If your unit has two compressors, you’ll need two ICM870 devices. The ICM870-32A soft start works with 2-stage HVAC units and are made for use in homes, businesses, RVs, and boats.
The ICM870-32A uses a self-learning system to adjust the power surge for each setup while keeping track of system health, voltage, current, and the compressor’s startup and condition. If there’s a problem, it will stop working, start a 3-minute reset routine, and show a fault warning with its LED light.
Features
- 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
Which Model Do I Need?
Refer to your service panel or user manual to determine your actual RLA rating.
ICM870-9A: For use with a Compressor Load Amp Rating (RLA) of up to Maximum of 9A
ICM870-16A: For use with a Compressor Load Amp Rating (RLA) of 9.1-16A Maximum
ICM870-32A: For use with a Compressor Load Amp Rating (RLA) of 16.1-32A 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. PLEASE choose the ICM870 based on RLA or by using the size vs tonnage chart shown below.
If you are experiencing issues with your product, please contact ICM product support (1-800-365-5525) as they may be able to provide a simple solution to your issue. You must have a case ID number from ICM support before returning an ICM870 product.
Air Conditioning & Heat Pump Loads – Average
This chart reflects average conversions of Single-Phase Air Conditioning and Heat Pump Tonnage, BTU’s, HP, and RLA. Please refer to your user manual or service panel to determine your actual RLA before deciding which model ICM870 you need.
- Size: *3 Ton; BTU: 36,000; RLA: 16; ICM870 Model: 16A
- Size: 4 Ton; BTU: 48,000; RLA: 22; ICM870 Model: 32A
- Size: 5 Ton; BTU: 60,000; RLA: 26; ICM870 Model: 32A
- Size: 6 Ton; BTU: 72,000; RLA: 32; ICM870 Model: 32A
* NOTE: for 3-ton units, use ICM870-32A if RLA exceeds 16A
ICM870-16A Comparable Amperage Crosses
The ICM870-32A model replaces amperage-corresponding models from the following manufacturers:
- Micro-Air (Easy Start)
- Dometic (Smart Start)
- Network RV (Soft Start)
- Hyper Engineering (Sure Start)
- Carlo Gavazzi (Smooth Starter)
Notes
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 Emmerson Core Sense modules can be bypassed when using the ICM870 Series Soft Starts. Unfortunately, the Comfort Alert cannot be bypassed and therefore ICM870 cannot be used.
