WRU01001 is a wireless, battery powered HMI unit. The device features temperature and humidity, the values of which can be displayed to user on a large LCD display. It features a native modbus map that grants seamless integration into the DDC/SCADA system. The communication is based on the encrypted Midam KFP protocol, which allows to update the device firmware on a wireless basis.

APPLICATION

HVAC control
measurement of temperature, humidity
display of status values
wireless integration into SCADA control systems

FUNCTION

The wireless room unit measures temperature and relative humidity. It allows to set the desired temperature setpoint and operating modes using the rotating knob. The values are transmitted through the 868 MHz unlicensed band to the WCOM51 gateway. There is also an option without rotating knob and display available. The room unit features a native modbus map with the direct read and write functionality. The modbus map is available in a separate document. All settings and configuration are also stored in a modbus register, directly in the device. It is necessary to pair the device before first use.

SCADA system integration

The controller can be integrated into DDC or SCADA systems directly via the WCOM51 wireless gateway.

PAIRING

To pair your own sensors with the WCOM51 GSM gateway, the freely downloadable KFP-Lite software is available, which communicates with the gateway using the WUSB01 wireless USB configurator. Both devices must be powered and placed in close proximity to each other. Using the search function in the software interface, you can view a list of all available devices in range and assign or modify parameters based on the wireless identification code for each individual device.

Using KFP-Lite, it is possible to change the communication frequency (default value 868.95 MHz).
