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

Product Description

XY-WTH1 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 Function:

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'.

1. 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;

1. 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;

1. Temperature correction function OFE (-10.0 ~ 10℃):

       The system is working for a long time and may be biased, through this function correction, the actual temperature = measuring temperature + calibration value;

How to set the start/stop temperature:

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, dehumidificationmode'D'.
Start humidity< stop humidity, humidificationmode 'E'.

1. Dehumidificationmode:

When the humidity≥Start humidity,relay conduction, green led on, dehumidification equipment begin to work;

When the humidity≤Stophumidity,relay disconnect, green led off, dehumidificationequipment stop to work;

1. Humidificationmode:

When the humidity≤Start humidity,relay conduction, green led on, humidificationequipment begin to work;

When the humidity≥Stophumidity,relay disconnect, green led off, humidificationequipment stop to work;

1. Humidificationcorrection 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;

How to set the start/stop humidity:

1. In the running interface, Long Press ' RH+ ' key more than 3 seconds, into the start humiditysettings 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 humiditysettings 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;

1. 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;

1.  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;

How to enable/disable relay:

       In the running interface, Short press ' TM-' key,enable/disablethe temperature relay(ON: enableOFF:disable), back to the running interface, if the temperature relay is disable, the temperature symbol ' ℃ ' 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.
