Checking operation data
Operation data can be checked with remote
control unit operation.
1. Press the button.
The display change " "
2. Press the (SET) button while
" " is displayed.
When only one indoor unit is connected to
remote controller, " " is
displayed (blinking indication during data
loading).
Next, operation data of the indoor unit
will be displayed. Skip to step 7.
4. When plural indoor units is connected, the
smallest address number of indoor unit
among all connected indoor unit is displayed.
[Example]:
" " (blinking 1 seconds)
" " blinking.
5. Select the indoor unit number you would
like to have data displayed with the
button.
6. Determine the indoor unit number with the
(SET) button.
(The indoor unit number changes from blinking indication to continuous indication)
" " (The address of selected indoor unit is blinking for 2 seconds.)
" " (A blinking indication appears while data loaded.)
Next, the operation data of the indoor unit is indicated.
7. Upon operation of the button, the current operation data is displayed in order from data
number 01.
The items displayed are in the above table.
Depending on models, the items that do not have corresponding data are not displayed.
8. To display the data of a different indoor unit, press the
the indoor unit selection screen.
9. Pressing the button will stop displaying data.
Pressing the (RESET) button during remote control unit operation will undo your last operation and
allow you to go back to the previous screen.
If two (2) remote controllers are connected to one (1) inside unit, only the master controller is available for trial
operation and confirmation of operation data. (The slave remote controller is not available.)
