1 .D8 is the temperature relay indicator lamp.Heating (cooling) equipment begins to work
2 .when the D8 light is turn on.
3 .D9 is a humidity indicator relay indicator lamp. Humidification/ dehumidification
4 . equipment began to work when the
D9 light is turn on.
5 .The display is showing the real time humidity value when the green D5 light is turn on.
6 .The display is showing the real time temperature value when the D5 lamp goes out .
Function description:
1. High temperature start - cooling mode:
Refrigeration equipment begins to work when the starting temperature value is greater than the stop temperature value and the temperature measurement is greater than or equal to the beginning temperature. Refrigeration equipment will stop working when the temperature measurement is less than or equal to the stop temperature. For example, Set the starting temperature to 20ºC, Stop temperature is 15ºC, D8 light is turn on and refrigeration equipment work when the detection temperature is greater than or equal to 20ºC. D8 light went off and refrigeration equipment will stop working when the temperature value is less than 15ºC.
2. Low temperature start - heating mode:
Heating equipment begins to work when the starting temperature value is less than the stop temperature value and the temperature is less than or equal to the beginning temperature. Heating equipment will stop working when the test temperature is greater than or equal to the stop temperature. For example, Set the starting temperature to 15ºC,Stop temperature is 20ºC. D8 lights is turn on and heating equipment begins to work when the temperature measurement value is less than or equal to 15ºC. D8 light went off and heating equipment to stop working when the temperature measurement value is greater than or equal to the stop temperature.
3. High humidity start - Desiccant mode:
The system automatically determines the mode of the dehumidification when the starting humidity value is higher than the value of the stop humidity.In this mode, dehumidification equipment to start work when humidity detection is greater than or equal to the beginning of humidity. Dehumidification equipment will stop working when the humidity detection is less than or equal to the stop humidity. For example, Set the starting humidity to 60 %RH, Stop humidity is 40 % RH. Indicator light D9 lamp is turn on and dehumidification equipment start to work when the detected humidity value greater than or equal to 60%RH. Indicator light D9 went off and dehumidification equipment to stop working when Humidity detection value is less than or equal to 40%RH.
4. Low humidity start - humidification mode:
The system automatically enters the humidification mode when the set start humidity is less than the value of the humidity value. In this mode, Humidification equipment began to work when the humidity detection is less than or equal to the beginning of humidity. Humidification equipment will stop working when the humidity detection is Greater than or equal to the beginning of humidity. For example, Set the starting humidity to 40%RH, Stop humidity is 60%RH, Indicator light D9 is turn on and humidification equipment into the work when the humidity detection value is less than or equal to 40%RH. Indicator light D9 went off and humidification equipment to stop working the humidity detection value is greater than or equal to
60%RH.
5. Temperature alarm mode:
Display showing Axx (default is A00) and flashing in the boot 3 seconds, You can use "+"and "-" to set the alarm Mode, Alarm modes are defined as follows:
A00: alarm function off (default)
A01: the currently detection of humidity beyond the starting temperature or stop temperature of 1ºC,buzzer alarm.
A02: the currently detection of humidity beyond the starting temperature or stop temperature of 2ºC, buzzer alarm.
A03: the currently detection of humidity beyond the starting temperature or stop temperature of 3ºC, buzzer alarm.and so on, max can be set A30.For example ,Set alarm mode A03, Starting temperature is 20ºC, Stop temperature is 30ºC, Buzzer sound alarm when the measured temperature is above 33ºC or below 17ºC.
Concrete setting method:
Notes: The following settings are automatically saved to EEPROM
1. Set start temperature:
Long press S button for 3 seconds, Red light D3 start flashing. Display showing starting temperature value at this moment, Press + and - button to adjust this value, Long press is continuous adjustment. Long press S button to exit the adjustment after the adjustment is completed or automatic exit without key action in 10S.
2. Set stop temperature:
Long press S button for 3 seconds, Red light D3 start flashing. Short press SET button once again and red LED D3 long bright, Display showing stop temperature value at this moment, Press + and - button to adjust this value, Long press is continuous adjustment. Long press S button to exit the adjustment after the adjustment is completed or automatic exit without key action in 10S.
3. Set up the starting humidity:
Long press S button for 3 seconds, Red light D3 start flashing. Short press SET button
twice again and red LED D4 start flashing. The display screen displays the starting
humidity value, this value can be adjusted by pressing the + and - buttons, long press
is continuous adjustment. Long press S button to exit the adjustment after the adjustment is completed or automatic exit without key action in 10S.
4. Set the stop humidity
Long press S button for 3 seconds, Red light D3 start flashing. Short press SET button three times again and red LED D4 start flashing. Display screen displays the value of the stop humidity at this time, this value can be adjusted by pressing the + and - buttons, long press is continuous adjustment. Long press S button to exit the adjustment after the adjustment is completed or automatic exit without key action in 10S.
5. Set the temperature model
Long press S button for 3 seconds, Red light D3 start flashing. Short press SET button four times again and red LED D3 and LED D4 start flashing at the same time. At this time the display screen display "C" or "F", this value can be adjusted by pressing the + and - buttons. C means that the current temperature model is degrees Celsius, F means that the current temperature pattern is Fahrenheit. Long press S button to exit the adjustment after the adjustment is completed or automatic exit without key action in 10S.
6. Set alarm mode
