1.Description: XY-WFWT is a digital temperature/humidity controller module with APP Sinilink control. It can be widely used at Smart home,Industrial control,Automatic irrigation,Indoor ventilation.Protection equipment. 2.Features: APP intelligent control and monitoringimultaneous temperature and humidity detection. elsius and Fahrenheit display. Automatic recognition working mode3.Temperature function: Automatic recognition working mode: XY-WFWT can automatically select the working mode according to the Start Temperature and Stop Temperature. It works in Cooling Mode if Start Temperature is greater than stop temperature. It works in Heating Mode if Start temperature is less than stop temperature.Cooling Mode: Relay turn ON and Red Indicator turn ON and Refrigeration equipment starts working if connect load when Current Temperature is greater than Start Temperature. Relay turn OFF and Red Indicator turn OFF and Refrigeration equipment stops working if connect load when Current Temperature is less than Stop Temperature.Heating mode: Relay turn ON and Red Indicator turn ON and Heating equipment starts working if connect load when Current Temperature is less than Start Temperature. Relay turn OFF and Red Indicator turn OFF and Heating equipment stops working if connect load when Current Temperature is more than Stop Temperature. Set Start/Stop Temperature: User can set Start/Stop Temperature on APP and also can set calibration value.Colour: Blackmaterial: plasticHumidity function: Automatic recognition working mode: XY-WFWT automatically selects the working mode according to the Start Humidity and Stop Humidity. It works in Dehumidification Mode if Start Humidity is greater than Stop Humidity. It works in Humidification Mode if Start Humidity is less than Stop Humidity.Dehumidification Mode:Relay turn ON and RedIndicator turn ON and Dehumidification equipment starts working if connect load when Current Humidity is greater than Start Humidity.Relay turn OFF and Red Indicator turn OFF and Dehumidification equipment stops working if connect load when Current Humidity is less than Stop Humidity.Humidification mode:Relay turn ON and Red Indicator turn ON and Humidification equipment starts working if connect load when Current Humidity is less than Start Humidity.Relay turn OFF and Red Indicator turn OFF and Humidification equipment stops working if connect load when Current Humidity is more than Stop Humidity.Note:It is a relay output mode and cannot be used as a power module. It cannot output voltage. The load needs to be connected to a separate power supply.At first time when pairing,phone must be connected to WIFI from router.It is not need connect to WIFI after pairing success.Package Contents:1 x Remote Controller ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
