Product functions are mainly classified into two categories: temperature function and humidity function;

The temperature function is as follows:

1.  Automatic recognition of working mode:

The system automatically recognizes the working mode according to the start temperature/stop temperature;

Starting temperature>stop temperature, cooling mode ‘C’;  starting temperature;

2.  Cooling mode:

When the detection temperature ≥ the starting temperature, the relay is turned on, the red indicator light is on, and the refrigeration equipment starts to work;

When the detected temperature is less than or equal to the stop temperature, the relay is closed, the red indicator light is off, and the refrigeration equipment stops working;

3.  Heating mode:

When the detection temperature is less than the start temperature, the relay is turned on, the red indicator light is on, and the heating device starts to work;

When the detected temperature is greater than or equal to the stop temperature, the relay is closed, the red indicator light is off, and the heating device stops working;

4.  Temperature correction function OFE (-10.0 ~ 10.0℃):

The system works for a long time, and there may be deviations.  Through this function, the actual temperature=measured temperature+calibration value;

How to set the start/stop temperature:

1.  In the running interface, press and hold the ‘TM+’ key for more than 3 seconds to enter the startup temperature setting interface.  The test can be used to modify the parameters through the TM+ TM- keys.  After the parameter modification is completed, wait 6 seconds to automatically exit and save;

2.  In the running interface, press and hold the ‘TM-’ key for more than 3 seconds to enter the stop temperature setting interface.  The test can be used to modify the parameters through the TM + TM- keys.  After the parameters are modified, wait for 6 seconds to automatically exit and save;

Humidity functions are as follows:

1.  Automatic recognition of working mode:

The system automatically recognizes the working mode according to the start humidity/stop temperature;

Start humidity> stop humidity, dehumidification mode ‘d’;  start humidity 

2.  Dehumidification mode:

When detecting humidity ≥ start humidity, the relay is turned on, the green indicator light is on, and the dehumidification equipment starts to work;

When the detected humidity is less than or equal to the stop humidity, the relay is closed, the green indicator light is off, and the dehumidification equipment stops working;

3.  Humidification mode:

When the detected humidity is less than the start humidity, the relay is turned on, the green indicator light is on, and the humidifying device starts to work;

When detecting humidity ≥ stop humidity, the relay is turned off, the green indicator light is off, and the humidifying device stops working

4.  Humidity correction function RH (-10.0 ~ 10.0℃):

The system works for a long time, and there may be deviations.  Through this function, the actual humidity = measured humidity + calibration value;

How to set start/stop humidity:

1.  In the running interface, press and hold the ‘RH+’ key for more than 3 seconds to enter the start humidity setting interface.  The test can be used to modify the parameters through the RH+ RH- key.  After the parameters are modified, wait for 6 seconds to automatically exit and save;

2.  In the running interface, press and hold the ‘RH-’ key for more than 3 seconds to enter the stop humidity setting interface.  The test can be used to modify the parameters through the RH+ RH- key.  After the parameters are modified, wait for 6 seconds to automatically exit and save;

Operation interface description:

Working mode display.  After the start temperature/humidity, stop temperature/humidity and other parameters are set, the current mode ("H/C", "E/d") will be displayed in front of the temperature/humidity;

When any relay is turned on, the upper left corner of the interface displays "OUT".  If the temperature relay is turned on, the temperature operating mode "H/C" flashes to indicate a reminder;  if the humidity relay is turned on, the humidity operating mode "E" flashes /d", as a reminder;

Other functions:

1.  Remote reading/setting of parameters:

You can set parameters such as start temperature/humidity, stop temperature/humidity, and temperature/humidity correction through UART;

2.  Real-time reporting of temperature/humidity:

If the temperature/humidity report function is turned on, the product will detect the temperature/humidity and relay status at 1s intervals and transmit it to the terminal via UART, which is convenient for data collection;

3. Relay enable (open by default):

If the relay enable is turned off, the relay remains off;

How to modify the temperature/humidity correction value:

1. In the running interface, double-click the ‘TM+’ key to enter the correction value setting interface; the lower line displays the correction value type, and the upper line displays the specific value; (OFE: temperature correction value RH: humidity correction value)

2. At this time, short press the ‘TM-’ key to switch the parameter to be modified, and use the RH+ RH- key to modify the specific value; long-press and short-press are supported;

3. After the parameter modification is completed, double-click the ‘TM+’ key to exit the correction value setting interface and save the data;

How to turn on/off the relay enable switch:

In the running interface, short press the'TM-' key to turn on or off the temperature relay enable (on: turn on OFF: turn off). After returning to the running interface, if the temperature relay is off, the temperature symbol'℃' will flash, Reminder.

In the running interface, short press the'RH-' key to turn on or off the humidity relay enable (on: open OFF: close). After returning to the running interface, if the humidity relay is in the off state, the humidity symbol'%' will flash, Reminder.
