10-1-6. Monitor Function of Remote Controller Switch

Calling of sensor temperature display

<Contents>

Each data of the remote controller, indoor unit and outdoor unit can be understood by calling the service

monitor mode from the remote controller.

<Procedure>

Push + buttons simultaneously for 4 seconds to call

the service monitor mode.

The service monitor goes on, the header indoor unit No. is displayed

at first and then the temperature of CODE No.

is displayed.

Push temperature set

buttons and then change the

CODE No. of data to be monitored.

The CODE No. list is shown below.

Push

UNIT LOUVER

(left side button) button to select the indoor unit to be monitored.

Each data of the indoor unit and its outdoor units can be monitored.

Pushing button returns the status to the usual display.

*1 The indoor discharge temperature of CODE No.

is the estimated value from TC or TCJ sensor.

Use this value to check discharge temperature at test run.

(A discharge temperature sensor is not provided to this model.)
• The data value of each item is not the real time, but value delayed by a few seconds to ten-odd

seconds.

• If the combined outdoor unit is one before 2 or 3 series, the outdoor unit data [6D], [70], [72] and [73]

are not displayed.
