Wireless Function
The wireless room sensor WRU01009 measures temperature and relative humidity. The values are transmitted through the 868 MHz unlicensed band to the WCOM51, or WCOM01 gateways. Embedded AES 128-bit, provides the most secure encryption standard for wireless connections. There is also an option with rotating knob and display available ( refer to WRU01001 HMI room unit ) to provide a variety of possibilities for building up a project. The device has factory-set values to ensure the correct default function and allows direct reading and writing of values to the Modbus map, which is available in a separate document. All settings are also stored in the Modbus map directly in the device. Before using the device for the first time, it is necessary to pair it and it is recommended to perform individual configuration, especially to change the encryption password.
Aplication
- HVAC control
- Measurement of temperature and humidity
- Display of status values
- Wireless integration into SCADA control systems
Pairing
Two devices are required for mutual communication. Both must be powered and located in close proximity to each other. Usually, wireless gateway or configuration dongle is used to set up remote wireless devices. Use look-up function in software tool to display a list of all available devices in range and assign or adjust parameters based on wireless ID code for each single device. There is a comprehensive help section integrated in the software tool to provide support during the wireless device set up procedure.
SCADA system integration
The controller can be integrated into DDC or SCADA systems directly via the WCOM51, WCOM01 wireless gateways or fancoil controller WFC01001 respectively.
Midam KFP Password change
Prior to the first use, the encryption password (default “MIKROKLIMA1234AB”) must be changed using the WUSB01 configuration dongle and the relevant software tool.
