Judgment by Indoor/Outdoor Unit Diagnostics
Enter diagnostics mode - press for five seconds Mode button in any operation mode. Acknowledgment
is by 3 short beeps and lights of COOL and HEAT LED’s. Then, every short pressing of Mode button
will scroll between Indoor and Outdoor unit diagnostic modes by the acknowledgment of 3 short
beeps and lighting of COOL and HEAT LED’s.
During the Outdoor unit diagnostics all four Indoor LED’s (STBY, Operate, Filter and Timer) are
blinking. When Indoor diagnostics is displayed, all four LED’s (STBY, Operate, Filter and Timer) are
ON.
When system enters diagnostics mode, only one fault code is shown. Order of priority is from the
lower to the higher number. Diagnostics is continuously ON as long as power is ON. The current
system operation mode will not be changed.
If no fault occurred in the system, no fault code will be displayed during normal operation mode. The
last fault code will be displayed even if the system has recovered from that fault. The last fault will be
deleted from the EEPROM after the system has exit diagnostics mode.
In diagnostics mode, system fault / status will be indicated by blinking of Heat & Cool LEDs.
The coding method will be as follows:
Heat LED will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds. Cool LED
will blink during the same 5 seconds according to the following Indoor / Outdoor unit tables:
Note: 0 – OFF, 1-ON
