Section 1.7 - Button function instructions and button operation
：Press to enter SET mode when the transmitter is in normal displaying mode;
Press to get back to normal displaying mode when the transmitter is in SET mode.
：Add value (switch symbol)
：Reduce value
：Press to save temperature value and enter humidity SET mode if the transmitter
is in temperature SET mode ;
Press to save humidity value and enter normal displaying mode if the transmitter
is intemperature SET mode .
The basic flow of the HE500A setting interface is:
Temperature deviation value setting --> humidity deviation value setting --> °C / °F
switching setting.
1, HE500A power-on display instructions
The device is powered on normally and fully displayed as shown in Figure (1). After HE500A,
the version number 【V4.4】is displayed, as shown in Figure (2). After normal startup, it
enters the normal measurement state, and the screen displays the temperature value and
temperature symbol. The lower row shows the humidity value and humidity symbol, as
shown in Figure (3).

2, Enter the setting interface and temperature deviation
setting
Power on the HE500A and press the 【MENU】key for 2 seconds to enter the setting
interface. As shown in Figure (1), the LCD screen displays the set temperature 【SET.T】and
the initial temperature deviation value 【0.0】. At this time, press 【UP】(【DOWN】) key to
【add】(【decrease】) the deviation value, long press to accumulate (reduced), release the
button to stop accumulating (reduced). The display interface is shown in Figure (4).

3, Humidity deviation setting
After setting the temperature deviation value, press the 【MENU】key again to select the
humidity channel deviation value setting. After entering the humidity channel deviation
value setting interface, the LCD screen displays the setting humidity 【SET.H】 and the
humidity deviation value initial value【0.0】, also perform the addition and subtraction of
the deviation value of the current channel as above, until it is set to the desired value. The
display interface is shown in Figure (5).

°C Symbol °F Symbol
4, °C/°F Switch Settings
When the 【MENU】key is pressed again, the temperature symbol switching interface is
entered. At this time, the LCD screen displays the set temperature 【SET.°C】and the
temperature initial value symbol 【°C】; when the 【UP】/【DOWN】key is pressed, the
current temperature can be changed Symbol [°C] →[°F].
When all settings are completed, press the 【OK】key to save the setting data and the device
enters the normal measurement state.
The basic flow of the HE500M setting mode is:
Address Setting --> Baud Rate Setting --> C/F Switch Setting --> Over Temperature Alarm
Setting --> Low Temperature Alarm Setting --> Humidity High Alarm Setting - -> Humidity
under low alarm setting --> alarm switch setting --> temperature and humidity deviation
value setting.
The basic flow of the HE500N setting mode is:
C/F switching setting --> over temperature alarm setting --> low temperature alarm setting
--> humidity too high alarm setting --> humidity low alarm setting --> alarm switch Settings
--> Temperature and humidity deviation value settings.
1.7.3 - HE500M/N button operation instructions
1. HE500M/N power-on display
The HE500M/N is powered on and displayed normally as shown in Figure (1). The version
number 【V1.0】and the device address 【001】are displayed, as shown in Figure (2). After
normal startup, the device enters the normal measurement state, and the screen displays the
temperature value. And temperature symbol, the lower row shows the humidity value and
humidity No., as shown in Figure (3).

2. Address settings (HE500M)
Press and hold the 【MENU】button for 50ms to enter the setting interface, as shown in
Figure (4). The LCD screen displays the setting temperature 【SET】and the setting item 【
ADR】, indicating the setting address (address), and the default address 01 is displayed in the
center of the LCD screen. At this time, press the 【UP】(【DOWN】) key to perform the
deviation value. 【Plus】(【minus】) operation, long press to accumulate (reduced), release
the button to stop accumulating (reduced), the address value is greater than zero, less than
255.
3, Baud rate setting (HE500M)
Press the 【MENU】button again to display the screen display content as shown in Figure
(5); 2. Baud rate setting. Press the 【MENU】button again, the display screen display content
is shown in Figure (5); the LCD screen displays the set temperature 【SET】and the setting
item 【BAUD】, indicating the baud rate is set. The default baud rate is 9600 (9.6Kbit/s) At
this time, press the 【UP】(【DOWN】) button to set the baud rate of 2.4 Kbit/s, 4.8 Kbit/s,
9.6 Kbit/s, and 19.2 Kbit/s. As shown in the figure, Figure (6), Figure (7), Figure (8), Figure
