LCD. (See figure.)
(3) Press the temperature setting and buttons
and change the item code to the sensor address
of the sensor that you want to monitor.
(For the relationship between the sensor address
and the sensor type, refer to the below Sensor
Temperature Correlation Table.
(4) During group control and simultaneous-operation
multi control, press the button and change
to the unit that you want to monitor.
(5) Press the button to return to normal remote
controller operation.
The temperature display reads “- - - - ” for units that
