To configure the TZONE TZ-THT01 HVAC Temperature Transmitter, you can follow the steps below:

1. Connect the transmitter to your power supply and RS485 communication interface. The VCC wire should be connected to the positive power supply, the GND wire to the negative power supply, the RS485-A wire to the RS485-A terminal, and the RS485-B wire to the RS485-B terminal.

2. Set the serial port configuration using the following parameters:
   - Baud rate: Choose from 1200/2400/4800/9600/19200/38400/57600.
   - Data bits: Fixed at 8 bits.
   - Check: No check.
   - Stop bit: Fixed at 1 bit.

3. After configuring the serial port, send a soft reset command or power off and restart the transmitter for the changes to take effect.

4. You can also set the device address code and baud rate. The device address code can be set within the range of 1 to 254. The baud rate can be set to one of the supported options: 1200/2400/4800/9600/19200/38400/57600.

5. To read the temperature and humidity values from the sensor, you can use the Modbus-RTU function code 03. The sensor will respond with the temperature and humidity data in the information frame.

6. If you need to change the baud rate, you can use the Modbus-RTU function code 06. Specify the register address as 0005H and set the desired baud rate value.
