The Micro-Air EasyStart Breeze Bluetooth Soft Starter makes running your RV or marine air conditioner on limited power sources easier by reducing compressor startup current by up to 75%, helping smaller generators and inverter systems handle demanding air conditioning loads. Featuring advanced adaptive learning technology, Bluetooth diagnostics, and a compact IP65-rated enclosure, the EasyStart Breeze automatically optimizes compressor startup performance while minimizing noise, vibration, and electrical stress. Designed and manufactured in the USA, this UL-listed soft starter includes a convenient 40-inch wiring harness, integrated mounting flange, and intelligent electrical protection for reliable operation in RV rooftop systems, basement air conditioners, and compatible marine air conditioning applications.
Effective 8-17-2026 MicroAir discontinued the non-bluetooth variant, which was model ASY-399-X20, and named this as the replacement model.
Key Features
• Up to 75% Startup Current Reduction – Reduces compressor inrush current, making air conditioning operation more practical with limited shore power, generators, and compatible inverter systems.
• Bluetooth Connectivity – Monitor operation, access fault diagnostics, perform firmware updates, and manage settings through the free Micro-Air mobile app for iOS and Android.
• Adaptive Learning Technology – Intelligent multi-start learning algorithm automatically optimizes startup performance for the connected air conditioning compressor.
• Compact, Weather-Resistant Design – IP65-rated enclosure is approximately 40% smaller than the previous EasyStart 364 model, making installation easier in confined spaces.
• Reduced Compressor Stress – Smooth compressor acceleration reduces electrical and mechanical stress during startup, helping minimize wear and tear.
• Quieter Operation – Reduces compressor startup noise and vibration for a more comfortable RV or marine environment.
• Intelligent Electrical Protection – Integrated brownout, overcurrent, compressor stall, and power interruption protection help safeguard connected equipment.
• Smart Restart Delay – Prevents damaging rapid compressor restarts without introducing unnecessary delays during normal operation.
• Real-Time Fault Detection – Integrated monitoring identifies electrical abnormalities and compressor operating faults.
• Remote Relearning – Bluetooth-enabled relearning allows the EasyStart Breeze to adapt when transferred to another compatible air conditioner.
• Simplified Installation – Integrated mounting flange and included 40-inch wiring harness help streamline installation.
• Made in the USA – Manufactured by Micro-Air with UL-listed construction.

Check Before Ordering
• Verify that your air conditioner operates on 100–120V AC and uses a compatible single-phase compressor system.
• Confirm compatibility with your specific air conditioner model, especially for marine installations.
• Verify that sufficient mounting space is available and that the included 40-inch wiring harness will reach the required connections.
• A soft starter reduces compressor startup current but does not reduce the air conditioner's normal running power requirements. Confirm your generator or inverter can support the unit's continuous operating load.
• Each independently operated air conditioning compressor requires its own appropriately selected soft starter.
• Check the manufacturer's installation instructions for wiring requirements and application-specific considerations.
