Room Sensor missing / Short
E1 blinking
Indoor coil sensor missing / Short
E2 blinking
Outdoor coil sensor missing / Short
E3 blinking
Compressor overload
E4 blinking
Outdoor abnormal compressor overload trip or gas leak
E5 blinking
Outdoor coil sensor exist (MS Model)
E6 blinking
Hardware error (Tact switch pin short)
E7 blinking

E7 blinking
EEPROM error
EE blinking
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
