Product functions:

Two main categories of product functions: Temperature function and humidity function;

The functions of temperature are as follows:

1. Automatic recognition of working modes:

Automatic starting temperature/Stop the temperature and identify the working mode.

Starting temperature > stop temperature, cooling mode ‘C’; The starting temperature is less than the stop temperature and the heating mode is &lsquo.H’;

2. Refrigeration mode:

When the detection temperature is &ge, the starting temperature, the relay is turned on, the red indicator light is on, the refrigeration equipment starts to work.

When the temperature is &le, the temperature is stopped, the relay is turned off, the red indicator lights are out, and the refrigeration equipment stops working.

3. Heating mode:

When the detection temperature is &le, the starting temperature, the relay is turned on, the red indicator light is on, the heating equipment starts to work.

When the temperature is &ge, the temperature is stopped, the relay is turned off, the red indicator lights are out, and the heating device stops working.

4. Temperature correction functionOFE(-10.0 ~ 10.0Centigrade):

If the system works for a long time, there may be some deviation. Through this function, the actual temperature will be corrected. = Measuring temperature +Calibration value;

How to set up startup/Stopping temperature:

1. In the running interface, long press‘TM+’key3More than seconds, enterStarting temperatureSet up the interface, the test can pass.TM+ TM-Key modifies parameters, waiting for parameters to be modified, waiting.6sAutomatically quit and save.

2. In the running interface, long press‘TM-’key3More than seconds, enterStop temperatureSet up the interface, the test can pass.TM+ TM-Key modifies parameters, waiting for parameters to be modified, waiting.6sAutomatically quit and save.

The humidity function is as follows:

1. Automatic recognition of working modes:

Automatic starting humidity/Stop the temperature and identify the working mode.

Start humidity > stop humidity, dehumidification mode ‘d’; Start humidity < stop humidity, humidification mode ‘E’;

2. Dehumidification mode:

When the humidity &ge is detected, the humidity is started, the relay is turned on, the green indicator light is on, the dehumidification equipment begins to work.

When the humidity &le is detected, the humidity is stopped, the relay is turned off, the green indicator lights are put out, and the dehumidification equipment stops working.

3. Humidification mode:

When the humidity &le is detected, the humidity is started, the relay is turned on, the green indicator light is on, and the humidifying equipment begins to work.

When the humidity &ge is detected, the humidity is stopped, the relay is turned off, the green indicator lights are out, and the humidification equipment stops working.

4. Humidity correction functionRH(-10.0 ~ 10.0Centigrade):

If the system works for a long time, there may be some deviation. Through this function, the actual humidity is corrected. = Measurement of humidity + Calibration value;

How to set up startup/Stop humidity:

1. In the running interface, long press‘RH+’key3More than seconds, enterStarting humiditySet up the interface, the test can pass.RH+ RH-Key modifies parameters, waiting for parameters to be modified, waiting.6sAutomatically quit and save.

2. In the running interface, long press‘RH-’key3More than seconds, enterStop humiditySet up the interface, the test can pass.RH+ RH-Key modifies parameters, waiting for parameters to be modified, waiting.6sAutomatically quit and save.

Operation interface description:

The working mode shows that when the temperature is started/Humidity and stopping temperature/After the humidity and other parameters are set, the temperature is/The current mode will be displayed synchronously in front of humidity.”H/C”, ”E/d”);

Any relay is turned on, and the upper left corner of the interface is displayed.”OUT”If the temperature relay is turned on, the temperature mode of the scintillation display is displayed.”H/C”As a reminder, if the humidity relay is turned on, the humidity mode will be displayed.”E/d”As a reminder.

Other functions:

1. Parameter remote reading/Set up:

Can pass throughUARTSet the starting temperature./Humidity and stopping temperature/Humidity and temperature/Humidity correction and other parameters.

2. temperature/Humidity real-time report:

If the temperature is turned on/Humidity reporting function. 1sThe interval will detect temperature./Humidity and relay statusUARTIt is transmitted to the terminal for data collection.

3. Relay enable(Default opening):

If the relay is turned off, the relay remains in a state of disconnection.

How to modify temperature/Correction of humidity:

1. In the running interface,Double click ‘TM+’key Enter the correction value setting interface, downlink display correction value type, uplink display specific value;OFETemperature correction value RHHumidity correction value)

2. By passing short Click‘TM-’Key, toggle the parameters to be modified, throughRH+ RH-Key, modify specific value; support long press short press;

3. When the parameters are modified,Double click ‘TM+’The key is to exit the correction value and set up the interface and save the data.

How to open it/Turn off relay enable switch:

In the running interface, short press‘TM-’Key, open or closetemperatureRelay enable(on: open up OFF: shut down)After returning to the operating interface, if the temperature relay is in a closed state, the temperature symbol & lsquo; & rsquo; flashes to indicate a warning.

In the running interface, short press‘RH-’Key, open or closehumidityRelay enable(on: open up OFF: shut down)After returning to the running interface, if the humidity relay is turned off, the humidity symbol ‘%’ flicker, as a reminder.
