13.1. ALARM CODE DISPLAY

If malfunctioning occurs during system func-

tioning, the units show the relative alarm code

which easily permits to the After-Sales Service

Area to identify the cause of errors; such alarm

code will appear both on indoor unit (through

two-digit display and possibly through the flash-

ing symbols cooling and heating) and on out-

door unit (by flashing LEDs on the electronic

board); the following table indicates the alarm

codes and their causes.
