10A Digital Temperature Humidity Controller SHT20 DC 6V-30V high precision

XY-WTH1 Temperature and humidity control module high precision digital displayword double output automatic constant temperature and humidity control panelProduct adopts industrial-grade chip, high-precision SHT20 temperature andhumidity sensor.

FUNCTION
Product features are two main types of classification: the functions of temperatureand 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 2 Start temperature, relay conduction, red led on, refrigerationequipment begin to work,
When the temperature s Stop temperature, relay disconnect, red led off, refrigerationequipment stop to work;

3. Heating mode:
When the temperature s Start temperature, relay conduction, red led on, heatingequipment begin to work;
When the temperature 2 Stop temperature, relay disconnect, red led off, heatingequipment stop to work;

4. emperature 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 thestart 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 thestop temperature settings interface, can be modified by TM+ TM- key, to be modifiedafter the parameters, waiting for 6s automatic exit and save;

THE HUMIDITY FUNCTIONIS 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, dehumidificationequipment begin to work;
When the humiditys Stop humidity, relay disconnect, green led off, dehumidificationequipment stop to work;

3. Humidification mode:
When the humiditys Start humidity, relay conduction, green led on, humidificationequipment begin to work;
4. Humidification correction function RH (-10.0~10%)
The system is working for a long time and may be biased, through this functioncorrection, 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 thestart 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 thestop humidity settings interface, can be modified by RH+ RH- key, to be modifiedafter 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 atthe front of temperature/humidity, when the setting of temperature/humidity andstop temperature/humidity are completed.
Any relay conduction, the upper-left corner of the interface display "out", if thetemperature relay conduction, the flashing display temperature working mode "H/Cto show reminders; if the humidity relay conduction, then flashing display humidityworking mode "E/d", as a reminder;

How to enable/disable relay:
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 isdisable, 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 isdisable, the humidity symbol % ' flashes, as a reminder.
