Multi-Brand Inverter Air Conditioner Tester

Professional Diagnostic Scanner for Inverter AC Systems

Professional diagnostic tool designed for technicians who work with inverter air-conditioning systems.

This multi-brand inverter AC tester supports quick diagnostics, system activation, and fault detection in compatible outdoor units from multiple manufacturers. It allows technicians to control and test an outdoor unit without the indoor unit, helping isolate problems involving control boards, compressors, communication signals, sensors, and power circuits.

Key features

• Multi-brand compatibility: Supports multiple inverter air-conditioner brands, including Haier, Midea, Gree, CHiQ, Hisense, AUX, TCL, Galanz, Skyworth, Yair, Soye, and others.
• Direct outdoor-unit testing: Runs and tests the compatible outdoor unit independently.
• Cooling and heating controls: Activates operating modes and frequency control during diagnostics.
• Automatic fault scan: Helps identify faults, communication problems, and operating errors.
• Quick brand selection: Dedicated controls support efficient field use.

Device functions

• Selection: Selects the air-conditioner brand.
• Confirmation / OK: Confirms operations and commands.
• Cooling: Controls cooling mode and frequency testing.
• Heating: Runs the outdoor unit in heating mode.
• Shutdown: Stops outdoor-unit operation.
• Scan: Scans for system malfunctions.

Wiring interface

The tester uses a three-wire connection: L (live), N (neutral), and S (signal / communication). This permits direct connection to a compatible outdoor-unit control board for testing and diagnostics.

Applications

• HVAC repair technicians and service centers
• Inverter control-board diagnostics
• Outdoor-unit testing and fault isolation
• Technical service training and repair verification

Safety notice

This device operates with high-voltage connections and must be used only by trained HVAC professionals. Before operation, verify wiring, voltage, polarity, equipment compatibility, and safety conditions. Incorrect connection may damage equipment or create electrical risk.
