Operation method:
In "C15" status, press the "MODE" button to enter outlet
temperature sensor query of IDU. Press "
IDU SN.
Display mode:
Temperature area: displays the project number of the current IDU.
Timer area: displays the temperature value.
-9 to 99
If the HBS network consists of only one IDU, the timer area
directly displays the temperature value in the "C14" interface.
No matter Fahrenheit or Centigrade remote signals are received,
the temperature is displayed in Centigrade.
When the wired controller displays the inlet-tube temperature after
receiving signals from the remote controller, the inlet-tube
temperature of the IDU that has the minimum project number in the
HBS network is displayed by default.
Operation method:
In "C16" status, press the "MODE" button to enter electronic
expansion valve opening degree query of IDU. Press "
to switch the IDU SN.
Display mode:
Temperature area: displays the project number of the current IDU.
Timer area: displays the opening degree value.
0-20
If the HBS network consists of only one IDU, the timer area
directly displays the opening degree value of electronic expansion
valve in the "C16" interface.
When the wired controller displays the opening degree of
electronic expansion valve after receiving signals from the remote
controller, the opening degree of electronic expansion valve of the
IDU that has the minimum project number in the HBS network is
displayed by default.

Operation method:
In "n6" status, press the "MODE" button to enter fault code query

Display mode:
Temperature area: displays the fault SN and fault code from left to
right (1-5, faults are arranged from the earliest to the latest).
Timer area: displays the project number of the ODU.
Operation method (n7 query is not supported for the slave wired
controller):
In "n7" status, the timer area is not displayed. Press the "MODE"
button to enter parameter query of ODU. The first bit in the
