1
Press and hold the and buttons
simultaneously for 4 seconds or longer.
2
The unit No. “X-X” (main unit No.), item code “
”
(sensor address), and servicing monitor “ ”
(sensor temperature) are displayed on the remote
controller LCD display.
3
Press the temperature setting /

4
If group control is in effect, press the
to select the unit to monitor.
button
Press the temperature setting buttons to select the
item code to change.
5
Press the button to return to normal remote
controller display.
NOTE
The temperature display appears as “- - - -” for unit that are not connected.
* If monitor mode is engaged while normal operation is in progress, only the parts of the LCD display shown in the
figure will change. Other parts continue to display the same information as during normal operation.
* Display shows a discharge temperature of
00XX at unit No. 1-1.

*Room temp. controlled: = Controlled room temperature
•Whenbodythermostatcontrolled:
Controlled room temperature = Indoor unit intake temp. (TA) – Intake temperature shift (*1)
•Remotecontrolthermostatcontrolled:
Controlled room temperature = Remote controller temp.
*1 Intake temperature shift: This is the shift value considered the temperature difference between the upper area
and lower area of the room in heating mode.
It is the value of the code “06” in the indoor unit’s EEPROM setting.
Cooling mode: = 0
