7.2.2 Human sensitive function
You can purchase the module of human sensitive function for this series. An interface for this module
is reserved on the main board of indoor unit.
(1) Interface instruction:
1) The printing is CN23 and the interface type is JST B3B-PH-K-S;
2) Electrical characteristic: 1-pin: +12V; 2-pin: detection port; 3-pin: GND; current: 150mA;
3) Working principle: when the module detects there is nobody in the room, 2-pin and 3-pin are
short-circuited and they are low electrical level; when there are somebody in the room, 2-pin
output is high electrical level.
(2) Function instructions:
In order to achieve this function, set it through wired controller and refer to the following operation
method. It is defaulted that this function is not activated; if this function is set and human sensitive module
is connected, the unit will control the ON/OFF of unit according to the signal detected by human sensitive
module. When there is nobody in the room and the unit is with wired controller,
icon will be displayed on
the wired controller; if the unit is without wired controller, there will be no display. The unit will control the
ON/OFF of unit according to the detected information.
(3) Setting method:
Under off state of the unit, press Function and Timer buttons at the same time for 5s to go to the
debugging menu. Press Mode button to adjust to “09” in temperature displaying zone. Timer zone displays
setting state and press ▲ or ▼ button to adjust. There are 2 selections:
1) Without human sensitive function (LCD displays 00)
2) With human sensitive function (LCD displays 01)
Choose the second selection and then press Enter/Cancel button to save and exit setting. Now,
human sensitive function is activated. The unit will memorize this setting status. The setting value will be
memorized after power failure. The detailed setting is as shown in the Figure below:
