INSTALLATION
- Unpack the product and open the top cover.
- Make cable connections accordingly.
3- If the product w ll be mounted on the wall, you can use the screws and dowels n the package.
4- It starts measuring 30 seconds after the product s energized. It’s recommended that the product remains in the environment for at least 5 minutes to get healthy measurement values..
5- It s recommended to use shielded cable as communication cable as well to prevent communication signals from being affected by external nfluences.
6- Since the communication on cable will create resistance, check the measurement values again after cable installation.
MODBUS RTU COMMUNICATION STRUCTURE
- RS485 Baud rate value n Modbus communication on s 9600 by default. Stop b t:1, Par ty: NONE.
- Default Slave ID s 82.
- Temperature values s kept in the holding register at address 2 (40003) and humidity values are kept in the holding register at address 3 (40004). Temperature and hum d ty nformat on can be obta ned by reading these registers.
Register map and default values table:
| Register | Address | Default Value | Read Write | Min. Value | Max. Value |
| Slave ID | 0 (40001) | 82 | R/W | 1 | 247 |
| Baud rate | 1 (40002) | 3 | R/W | 0 | 8 |
| Temp. Val. | 2 (40003) | – | R | – | – |
| Hum. Val. | 3 (40004) | – | R | – | – |
Slave ID and Baud rate can be changed via a Modbus communication. For this, the desired Slave ID s written to the register with address 0 (40001), which is the register where the Slave ID s located. L kew se, f the Baud rate s to be changed, the Baud rate can be changed by writing the value for the desired Baud rate according to the table below in the register with address 1 (40002).
| M n. | Max. |
| Value | Value |
| 0 | 1200 |
| 1 | 2400 |
| 2 | 4800 |
| 3 | 9600 |
| 4 | 14400 |
| 5 | 19200 |
| 6 | 38400 |
| 7 | 57600 |
| 8 | 115200 |
Press and hold the “Cal brat on” button to reset the changes made to the Slave Id or Baud rate to the default values. Wait until the Status (green) LED turns off (approx. 30 seconds). After the LED turns off, the button s released. Thus, Slave ID and Baud rate are returned to the default values.
CALIBRATION
- Temperature and humidity measurement, Calibration cannot be done on the product. Calibration s done at the product on site.
- The need for Calibration due to the communication cable during use should be done on the control panel, not on the product.
