Temperature & Humidity Control w/ LCD Display - XY-WTH1

multifunction delay relay module.LCD display, very clear, easy to use, powerful.It can be widely used at Smart home,Industrial control,Automatic irrigation,Indoor ventilation.Protection equipment.

Applications

• Motor
• Robot
• Smart home
• Industrial control
• Automatic irrigation
• Indoor ventilation

Features

• Control accuracy is for temperature 0.1 °C and for humidity is too 0.1 step – it is a great advantage !
• Measurement accuracy is at a high level, measuring both temperature and humidity
• Two independent relays, LED signalization of Work status is fine
• Calibration in 0.1 steps, it is good to own, the instrument is coming very accurately
• The LED display has nice backlit
• Very good price for 12-13usd you get two controllers in one package

Specifications

Package

• 1pcs XY-WJ01

Load can be max 10A .
LOAD means a heater or a cooling compressor for TM relays. The humidifier or dehumidifier is for HM relay output
The relay output is not it is not “electrically” connected to the XY-WTH1 electronics so we can also control the 110V or 220V voltage. 

  How to set the temperature for heating or cooling:

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’

How to set the start/stop temperature:

1. In the running interface, Long Press TEMP+ key more than 3 seconds, into the start temperature settings interface, can be modified by TEMP+ TEMP- key, to be modified, waiting for 6s automatic exit and save    

2. In the running interface, Long Press TEMP- key more than 3 seconds, into the stop temperature settings interface, can be modified by TEMP+ TEMP- key, to be modified after the parameters, waiting for 6s automatic exit and save

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.

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.

OFE   -Temperature correction function calibration (-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 humidity control humidification or dehumidification:

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’

How to set the start/stop humidity:

1. In the running interface, Long Press ‘ HUMI+ ‘ key more than 3 seconds, into the start humidity settings interface, can be modified by HUMI+ HUMI– key, to be modified, waiting for 6s automatic exit and save.

2. In the running interface, Long Press ‘ HUMI-‘ key more than 3 seconds, into the stop humidity settings interface, can be modified by HUMI+ HUMI- key, to be modified after the parameters, waiting for 6s automatic exit and save.

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.

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.

RH-Humidification correction function calibration   (-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.
