Features Product features are two main types of classification: the functions of temperature and humidity. The automatic identification of work mode. 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. The system automatically according to the start/stop temperature, identify work mode. Features:1.Product features are two main types of classification: the functions of temperature and humidity;2.Function of temperature are as follows:The automatic identification of work mode:3.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".4.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;5.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;6.Temperature correction function OFE (-10.0 ~ 10℃):7.The system is working for a long time and may be biased, through this function correction, the actual temperature = measuring temperature + calibration value; Specification:Model:XY-TR01Temperature range: -20~60℃Humidity range: 00%-100%Control probe: integrated sensorOutput type: relay outputSize: 57*60*20mm/2.2*2.4*0.8inWeight: Approx.77g/2.7oz Package list:1 x Temperature and humidity Module Package List
