The Hisense Hi-Checker 3.0 is a Bluetooth diagnostic tool designed for the installation, commissioning, troubleshooting and maintenance of Hisense inverter systems. Connected to the outdoor unit, it lets technicians view real-time operating data, fault history and system parameters directly on a smartphone through the Hi-Service app. Two connecting cords are included, one for residential units and one for multi-zone and light commercial units, and three status LEDs confirm power, app connection and outdoor unit communication. It supports a wide range of Hisense North American systems, including Hi-Multi, Hi-Uni, Hi-Pro HD and Hi-Ultra HD.
