COMPLETION OF FUNCTION SETTING MODE
6) To clear the function setting mode and return to the regular display, hold down the three
buttons of SET TEMP. V, SET TEMP. Λ and FAN at the same time.
* If no key entry is made for 60 seconds, even though none of the above buttons is pressed,
the function setting mode will automatically be cleared.
(If the function setting mode is automatically cleared while setting addresses, activate the
mode again according to the procedure in step 2) above.)
SETTING UP EACH INDOOR UNIT
Repeat the procedures in steps 1) through 6), and set up the indoor units requiring function
setting.
RESET THE POWER AFTER SETTING UP FUNCTION OF ALL
INDOOR UNITS
Important
If the reset is not performed, function can not be read in normally.
After all the functions have been set, the circuit breaker needs to be switched off
for at least 2 minutes.
After the 2 minutes has passed, power can be restored.
The set function is stored in the PCB and will remain in memory even when the
power is turned off.
However setting function is effective after power reset.
Record the function set in the indoor unit on a label, etc., and affix the label to the
unit so it can be used for after-sales service operations.
