Mode number
Modes 01 to 14 can be activated by pressing buttons and simultaneously, and modes 15 to 28 by pressing buttons and .
[Operating Procedure]
Check the setting items provided by function selection.
If settings for a mode are changed by function selection, the functions of that mode will be changed accordingly. Check all the current settings according to steps to, fill in the "Check" column in Table 1, and then change them as necessary. For factory settings, refer to the indoor unit's installation manual.
Switch off the remote controller.
Hold down the ( mode is 15 to 28)and buttons simultaneously for atleast 2 seconds. will start to flash, and then the remote controller's display content will change as shown below.
FILTER
Set the outdoor unit's refrigerant address.
Press the [ CLOCK] buttons ( and ) to select the desired refrigerant address. The refrigerant address changes from "00" to "15".
(This operation is not possible for single refrigerant systems.)
* If the unit stops after FUNCTIONSELECTION flashed for 2 seconds or "88" flashes in the room temperature display area for 2 seconds, a transmission error may have occurred.
Check to see if there are any sources of noise or interference near the transmission path.
NoteIf you have made operational mistakes during this procedure, exit function selection (see step ), and then restart from step . Set the indoor unit number.
Press the ON/OFF button so that "- -" flashes in the unit number display area.
Press the [ CLOCK] buttons ( and ) to select the unit number of the indoor unit for which you want to perform function selection. The unit number changes to "00", "01", "02","03",04" and "AL" each time a button is pressed.
* To set modes 01 to 06 or 15 to 22 select unit number "00".
* To set modes 07 to 14 or 23 to 28 carry out as follows:
• To set each indoor unit individually, select " 01" to "04".
• To set all the indoor units collectively, select " AL".
Confirm the refrigerant address and unit number.
Press the MODE button to confirm the refrigerant address and unit number.
After a while, "- - " will start to flash in the mode number display area.
When the refrigerant address and unit number are confirmed by pressing the MODE button, the corresponding indoor unit will start fan operation. This helps you find the location of the indoor unit for which you want to perform function selection. However, if "00" or "AL" is selected as the unit number, all the indoor units corresponding to the specified refrigerant address will start fan operation.
* "88" will flash in the room temperature display area if the selected refrigerant address does not exist in the system.
Furthermore, if "F" appears and flashes in the unit number display area and the refrigerant address display area also flashes, there are no units that corre- spond to the selected unit number. In this case, the refrigerant address and unit
number may be incorrect, so repeat steps and to set the correct ones. * When grouping different refrigerant systems, if an indoor unit other than the one to which the refrigerant address has been set performs fan operation, there may be another refrigerant address that is the same as the specified one.
In this case, check the DIP switch of the outdoor unit to see whether such a refrigerant address exists.
Select the mode number.
Press the [ TEMP] buttons ( and ) to set the desired mode number.
(Only the selectable mode numbers can be selected.)
Select the setting content for the selected mode.
Press the MENU button. The currently selected setting number will flash, so check the currently set content.
Press the [ TEMP] buttons ( and ) to select the desired setting number.
Register the settings you have made in steps to .
Press the MODE button. The mode number and setting number will start to flash and registration starts.
The mode number and setting number will stop flashing and remain lit, indicating the end of registration.
* If " - - - " is displayed for both the mode number and setting number and " " flashes in the room temperature display area, a transmission error may have occurred.
Check to see if there are any sources of noise or interference near the transmission path.
Complete function selection.
Hold down the ( mode is 15 to 28) and buttons simultaneously for at least 2 seconds. FILTER
After a while, the function selection screen will disappear and the air condi- tioner OFF screen will reappear.
* Do not operate the remote controller for at least 30 seconds after completing function selection. (No operations will be accepted even if they are made.)
