2.1 Equipment inspection before installation
Equipment list：
■ Temperature and humidity transmitter equipment 1 set
■ 2 expansion plugs, 2 self-tapping screws
■ Certificate of conformity, warranty card
2.2 Interface description
The power interface is a wide voltage power input of 10-30V. When wiring the 485 signal line, pay attention to the fact that the A\B lines cannot be connected in reverse, and the addresses of multiple devices on the bus cannot conflict.
2.2.1 Sensor wiring
2.3 Installation method
Special instructions:
（1）There are certain specifications and requirements for 485 line field wiring.
（2）When devices are connected to the 485 bus, ensure that the addresses of multiple devices are not repeated.
2.4 Installation matters
The following matters need to be noted when installing:
1. The transmitter should be placed vertically as much as possible to ensure that the sensor is below the transmitter when installed on the wall (the font on the transmitter is in the positive direction);
2. The installation height is the sitting height of the human body or the environmental area where the measurement is mainly required. At the same time, please pay attention to the following precautions:
1. Avoid installing in areas that are easy to transfer heat and will directly cause a temperature difference with the area to be measured, otherwise it will cause inaccurate temperature and humidity measurements.
2. Install in an area with a stable environment, avoid direct sunlight, away from windows and air conditioners, heating and other equipment, and avoid directly facing windows and doors.
3. Try to stay away from high-power interference equipment to avoid inaccurate measurements, such as inverters/motors, etc.
