button to confirm the refrigerant address and unit
number.
After a while, "- - " will start to blink in the mode number display area.
E 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 blink in the room temperature display area if the selected refrigerant
address does not exist in the system.
Furthermore, if
"F"
appears and blinks in the unit number display area and the
refrigerant address display area also blinks, 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 2 and 3 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 to perform 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.
