Temperature and Humidity Control Digital Display High Precision Dual Output Automatic Constant Temperature and Humidity Control Board

Temperature and humidity control module high precision digital display word double output automatic constant temperature and humidity control panel

Product adopts industrial-grade chip, high-precision SHT20 temperature and humidity sensor.

Product features are two main types of classification: the functions of temperature and humidity;
Function of temperature are as follows:

1. The automatic identification of work mode:
The system automatically according to the start/stop temperature, identify work mode;
Start temperature > stop temperature, cooling mode 'C'.
Start temperature < stop temperature, heating mode 'H'.

2. Cooling mode:
When the temperature ≥ Start temperature, relay conduction, red led on, refrigeration equipment begin to work;
When the temperature ≤ Stop temperature, relay disconnect, red led off, refrigeration equipment stop to work;

3. Heating mode:
When the temperature ≤ Start temperature, relay conduction, red led on, heating equipment begin to work;
When the temperature ≥ Stop temperature, relay disconnect, red led off, heating equipment stop to work;

4. Temperature correction function OFE (-10.0 ~ 10�b?:
   The system is working for a long time and may be biased, through this function correction, the actual temperature = measuring temperature + calibration value;
 

1. In the running interface, Long Press ' TM+ ' key more than 3 seconds, into the start temperature settings interface, can be modified by TM+ TM- key, to be modified, waiting for 6s automatic exit and save;
2. In the running interface, Long Press ' TM-' key more than 3 seconds, into the stop temperature settings interface, can be modified by TM+ TM- key, to be modified after the parameters, waiting for 6s automatic exit and save;
 
 
The humidity function is as follows:

1. The automatic identification of work mode:
The system automatically according to the start/stop humidity, identify work mode;
Start humidity> stop humidity, dehumidification mode 'D'.
Start humidity< stop humidity, humidification mode 'E'.

2. Dehumidification mode:
When the humidity≥ Start humidity, relay conduction, green led on, dehumidification equipment begin to work;
When the humidity≤ Stop humidity, relay disconnect, green led off, dehumidification equipment stop to work;
 
3. Humidification mode:
 When the humidity≤ Start humidity, relay conduction, green led on, humidification equipment begin to work;
When the humidity≥ Stop humidity, relay disconnect, green led off, humidification equipment stop to work;
 
4. Humidification correction function RH (-10.0 ~ 10%):
   The system is working for a long time and may be biased, through this function correction, the actual humidity = measuring humidity + calibration value;
 

1. In the running interface, Long Press ' RH+ ' key more than 3 seconds, into the start humidity settings interface, can be modified by RH + RH - key, to be modified, waiting for 6s automatic exit and save;
2. In the running interface, Long Press ' RH-' key more than 3 seconds, into the stop humidity settings interface, can be modified by RH+ RH- key, to be modified after the parameters, waiting for 6s automatic exit and save;
 
Running Interface Description:

Working mode shows that the current mode ("H/C", "E/d") will be synchronized at the front of temperature/humidity, when the setting of temperature/humidity and stop temperature/humidity are completed.
Any relay conduction, the upper-left corner of the interface display "out", if the temperature relay conduction, the flashing display temperature working mode "H/C" to show reminders; if the humidity relay conduction, then flashing display humidity working mode "E/d", as a reminder;
 
Other features:

1. Parameter remote read/set:
Through the UART, set the starting temperature/humidity, stop temperature/humidity, temperature/humidity correction parameters;
2. temperature/Humidity Real-time reporting:
If the temperature/humidity reporting function is turned on, the product will detect the temperature/humidity and relay status by the 1s interval, and pass the UART to the terminal to facilitate data collection;
3.  Relay enabling (by default):
If the relay is disable, the relay remains disconnected;
 
 How to modify the temperature/humidity correction value:

1. 1. In the operating interface, double-click the ' TM+ ' key to enter the correction of the set interface, the downward display correction of the type, the upward display of specific values; (OFE: Temperature correction value RH: Humidity correction value)
2. At this time by a short press ' TM-' key, switch to modify the parameters, through the RH+ RH-key, modify the specific value of the support long press short;
3. When the parameters have been modified, double-click the ' TM+ ' key, exit the correction positive setting interface, and save the data;

In the running interface, Short press ' TM-' key, enable/disable the temperature relay(ON: enable OFF: disable), back to the running interface, if the temperature relay is disable, the temperature symbol ' �b?' flashes to remind.
In the running interface, Short press ' RH-' key, enable/disable the humidity relay (ON: enable OFF: disable), back to the running interface, if the humidity relay is disable, the humidity symbol '% ' flashes, as a reminder.
