2. 2. Can display the current temperature and humidity in real time.
3. 3. With over limit alarm function.
4. 4. Relay working indication function.
5. 5. With power supply reverse protection function.The controller does not work when the power supply is connected to

the counter.

Indicator light:

1. 1. D8 is the temperature relay indicator lamp.Heating (cooling) equipment begins to work when the D8 light is turn on.
2. 2. D9 is a humidity indicator relay indicator lamp. Humidification/ dehumidification equipment began to work when the

D9 light is turn on.

1. 3. The display is showing the real time humidity value when the green D5 light is turn on. The display is showing the real

time temperature value when the D5 lamp goes out .

Key note:

Look at the picture 1, Buttons from left to right respectively SET，+ and - .

Function description:

1. 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 20℃, Stop temperature is 15℃, D8 light is turn on and refrigeration equipment work when the detection temperature is greater than or equal to 20℃. D8 light went off and refrigeration equipment will stop working when the temperature value is less than 15℃.

1. 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 15℃,Stop temperature is 20℃. D8 lights is turn on and Heating

equipment begins to work when the temperature measurement value is less than or equal to 15℃.D8 light went off and Heating equipment to stop working when the temperature measurement value is greater than or equal to the stop temperature.

1. 3. High humidity start - Desiccant mode:

The system automatically determines the mode of the dehumidification when the startting 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.

1. 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.

1. 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 1℃，buzzer alarm.

A02: the currently detection of humidity beyond the starting temperature or stop temperature of 2℃，buzzer alarm.

A03: the currently detection of humidity beyond the starting temperature or stop temperature of 3℃，buzzer alarm.

and so on, max can be set A30.

For example ,Set alarm mode A03, Starting temperature is20℃,Stop temperature is 30℃，Buzzer sound alarm when the measured temperature is above 33℃ or below 17℃。

Concrete setting method:

Notes: The following settings are automatically saved to EEPROM

1. 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.

1. 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.

1. 3. Set up thestarting 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.

1. 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.

1. 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.
