Operating test, address selector and fault code
Operating test
• Perform the operating test after the units have been installed in
position and the gas leak test has been completed.
• Check all electrical connections (instructions and wiring
diagram).
• Insert the batteries into the remote control and leave it OFF.
• Energise the system, turning the power supply ON.
• Press the and buttons of the infrared remote control and
hold them pressed for more than 5 seconds.
The display will be cleared,the time segments will display the
icon (Src =service test).
When test mode is selected,the unit operates as described
below:
• The green LED and the orange LED blink every 2 seconds.
• The indoor fan operates at low speed.
• The louver operates according to "Auto heat " or "Auto cool "
based on operating mode.
• The system works in Cool Mode at fixed compressor frequency
for 3 minutes.
• The system stops for 3 minutes.
• The system works in Heat Mode with fixed compressor
frequency for 3 minutes or until the indoor coil temperature is
greater than 40 °C.
During the cool mode and heat mode check the following
conditions:
1 . Difference between indoor ambient temperature and indoor unit
air discharge temperature must be greater than 3 °C.
2 . Indoor fan must operate at low speed.
3 . Louver must be in auto heat or cool louver based on operating
mode.
4 . No fault code must be signalled by the system.
If one of the above conditions is not positive,please check the
correct installation of the system.
• After test has been completed,press button
control to leave the test menu.
Note:
When 30 minutes have elapsed and no buttons have been
pressed,the remote control will automatically exit the test menu
and resume its normal operation.
Address selector
If you are installing two indoor units in the same room and you
want them to operate in independent mode,it is necessary to
assign each unit its own address so that each unit can operate via
its own remote control.
For configuration, proceed as follows:
Configuration (of the unit)
• Press the and buttons of the infrared remote control and
hold them pressed for more than 5 seconds.
• The display will be cleared,the time segments will display the first
configuration item (rAdr = remote address)and the temperature
segments will display the default value of this configuration item
(Ab = control of both indoor units).
• Press either the or button to change the default value (Ab)
to the new value (A) or (b).
• Press button repeatedly until "ZONE " is displayed.
• Press either the or button to change the default value of
Zone number (0) to the new value (0-240).
• Press button repeatedly until "A St " is displayed.
• Press either the or button to change the default value of
auto restart in last mode (On) to the new value of start in OFF
mode (OF).

• LOOK OUT!Whichever configuration value changed must be
transmitted to the indoor unit pressing
• Press button to leave the configuration menu.
Configuration (of the remote control)
• Press the and buttons of the infrared remote control and
hold them pressed for more than 5 seconds.
• The display will be cleared, the temperature segments will display
the first configuration item (CH =remote address)and the time
segments will display the default value of this configuration item
(Ab =control of both indoor units).
• Press either the or button to change the default value (Ab)
to the new value (A)or (b).
• Press button repeatedly until "tU " is displayed..
• Press either the or button to change the default value of
temperatures in Degrees Celsius (C)to the new value Degrees
Fahrenheit (°F).
• Press button repeatedly until "Hr " is displayed.
• Press either the or button to change the default value of
Maximum heating set point temperature admitted in Degrees
Celsius (32)or Degrees Fahrenheit (90)to the new value Degrees
Celsius (17-32)or Degrees Fahrenheit (63-90).
• Press button repeatedly until "Cr " is displayed.
• Press either the or button to change the default value of
minimum cooling set point temperature admitted in Degrees
Celsius (17)or Degrees Fahrenheit (63)to the new value Degrees
Celsius (17-32)or Degrees Fahrenheit (63-90).
• Press botton repeatedly until "CL " is displayed.
• Press either the or button to change the default value of
Time format as AM/PM (12)to the new value of 24 hours time
format (24).
• LOOK OUT! Whichever configuration value changed must
be confirmed pressing button each time.
• Press button to leave the configuration menu.
Note:
When 30 seconds have elapsed and no buttons have been
pressed,the remote control will automatically exit the
configuration menu and the procedure has to be restarted.
Fault code
The inside unit can detect any system fault and stop it at once.
The failure is recoverable based on the table VI below.
When a diagnostic is active,the green LED (P)and the orange
LED (R)blink 0.1 seconds on,0.1 seconds off and indicate a fault
code.
The orange LED (R)indicates the tens digits.
The green LED (P)indicates the unit digits.
Two seconds elapse between the orange LED and the green LED
lighting.
The sequence ends with both LEDs off for 4 seconds.
Example:
Fault code 12
• The orange LED blinks (it indicates the tens digits).
• Both LEDS are off for 2 seconds.
• The green LED blinks twice with a 0,5 seconds frequency.
• Both LEDS are off for 4 seconds.
The fault sequence described above is repeated until the fault has
been repaired.
If the fault code is lower than 10,the orange LED (R)is not
blinking.
