1. Utilize high-precision and high-stability digital temperature and humidity sensors for an accurate measurement and a rapid response. The large LCD/LED display clearly shows real-time temperature and humidity values simultaneously or on separate pages.                2. Users can freely set upper/lower limit alarm values and hysteresis for temperature and humidity parameters. Support multiple output modes: Single-channel control, Dual-channel independent control, and other control methods.         
3. Provide the relay output (Passive dry contact) to directly control the power supply for a series of devices, such as fans, heaters, air conditioners, dehumidifiers and alarm lights, with a typical load capacity up to 5 A.
