This is a digital temperature & humidity controller with wide humidity/temperature measuring and control range. This controller can control both temperature (heating or cooling) and humidity (humidifying or dehumidifying) at the same time. There are two LED display for temperature value(°C) and  humidity value(%RH) , three relays for loads(one for temperature controlling, one for humidity controlling, one for alarm device, one sensor module (contains both temperature and humidity sensors), and one input power socket.
 

Specifications:

• The measurement range of temperature: -20°C ~ 100°C
• The measurement accuracy of temperature: ±0.5℃
• The measurement resolution of temperature: 0.1℃(between -9.9°C ~ 99.9°C)
• Temperature control mode: On/Off Control, Heating mode, Cooling mode
• Relay contact capacity for temperature device: 10A/220VAC
• Slew range of temperature control(d value): 1°C ~ 25°C
• For example, if you choose Heat mode(Set HC to H). Set control value of temperature to 80°C. Set d value to 10°C. The heating device will be turned on when the temperature drop to 70°C. And the heating device will be turned off when the temperature reaches 80°C.
• The measurement range of temperature: 0% ~ 100%
• The measurement accuracy of Humidity: ±3%
• The measurement resolution of Humidity: 0.1%
• Humidity control mode: On/Off Control, Humidifying, Dehumidifying
• Relay contact capacity for humidity device: 10A/220VAC
• Slew range of humidity control(d value): 1% ~ 25%
• For example, if you choose Humidifying mode(Set HC to H). Set control value of humidity to 50%. Set d value to 10%. The humidifying device will be turned on when the humidity drop to 40%. And the humidifying device will be turned off when the humidity reaches 50%.
• Relay contact capacity for alarm device: 3A/220VAC
• Power consumption: < 3W
• Working temperature: 0°C - 60 °C
