System configuration
NOTE: If the selection is changed from “rc” (HP operation) to
cooling only and the remote control operating mode is auto or
heating, the operating mode is set to cool.
NOTE: If the “HR” is set to a value that is lower than “CR” and the
remote control operating mode is auto, the operating mode is set to

System configuration
Units are factory configured as heat pumps.
When a cooling only system is installed, it is necessary to change
the factory configuration.
Such operation must be performed by the installer as follows:
Cooling only configuration (of the system)
• 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 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 button
repeatedly until “UCFG” is displayed.
• Press either the
or
button to change the default value (HP)
to the new value (AC).
• Press
button to transmit the new configuration to the unit.
• Press
button to leave the configuration menu.
For other available configuration options, see table VI.
GFD Multisplit/T-Kit configuration
• 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 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).
• Push
button until will appear “GFdn” on the display.
• Through the buttons
and
to change the default value “1”
into 239 for T-KIT configuration or 240 for MULTISPLIT
configuration.
• Press the
button to send the configuration to the unit, which
will confirm with a “beep”.
• Press the
button to exit from this configuration menu.
Note:
When 30 seconds have elapsed and no buttons have been
