Error Code
Wired Handset : BRC51A62/64
When the system is on and an error occurs, the seven segments LED will blink an error code.
Each error code blinking represents different message as below:
Room Sensor missing / Short
Indoor coil sensor missing / Short
Outdoor coil sensor missing / Short
Compressor overload
Outdoor abnormal compressor overload trip or gas leak
Outdoor coil sensor exist (MS Model)
Hardware error (Tact switch pin short)
Indoor fan feedback error
EEPROM error
Wired Handset : BRC51D64
When the system is on and an error occurs, the ON/OFF LED on the LCD panel will blink and an error code
is shown. When the system is off and there is a thermistor error, the ON/OFF LED is off but the error code is
still displayed. Each error code represents different message as below:
