4.4 Memory Function
Press Mode and ▲ buttons at the same time for 5s under off state of the unit to turn on or cancel
memory function. If memory function is set,
is displayed. If not, indoor unit is defaulted to be off
after power recovery.
If memory function is set, indoor unit will resume original setting state after power failure and then
power recovery.
Note:
If cut off power with 5s after memorized content is changed, the memorized content may be
abnormal. Do not cut off power within 5s after memorized content is changed.
4.5 Door Control Function/Human Sensitive Function
Door control function or human sensitive function can be selected (More details please refer to
Debugging Function). These two functions can‟t be turned on at the same time.
When door control function is selected, the wired controller will work when the room card is inserted
and stop working when the room card is not inserted; when human sensitive function is selected, the wired
controller will work when it senses there is somebody in the room and stop working when it senses there is
nobody in the room. When the door control function senses the room card is not inserted or human
sensitive function senses there is nobody in the room, the wired controller will display
icon.
Notes:
① In long-distance monitoring or centralized control, no matter the room card is inserted or not,
the ON/OFF of unit can be controlled. If long-distance monitoring or centralized control
information is received when the room card is not inserted,
icon is cleared. When the
card is reinserted, door control function is judged to be turned on. If long-distance monitoring
or centralized control information is received when the room card is inserted, it will keep the
original status.
② The unit can not be controlled by buttons when the card is not inserted.
③ When door control function and human sensitive function have been set at the same time, it
is defaulted that door control function is valid and human sensitive function is invalid.
4.6 Switch between Fahrenheit and Centigrade
Under off state of the unit, press Mode and ▼ buttons at the same time for 5s to switch between
Fahrenheit and Centigrade.
4.7 Enquiry of Ambient Temperature
Under off or on state of the unit, press it for 5s to view the ambient temperature. In this case, timer
zone displays ambient temperature type 01 or 02. Ambient temperature zone displays the corresponding
temperature of that type. 01 stands for outdoor ambient temperature and 02 stands for the indoor ambient
temperature after compensation. Press Mode button to switch between 01 and 02. Pressing other buttons
except Mode button or receiving remote control signal will exit enquiry state. If there is no operation within
20s will also exit enquiry state.
