RTU-HTemp Display is a wall-mounted indoor sensor for measuring temperature and relative humidity. It combines a local LCD display with RS-485 / Modbus RTU communication, making it suitable for direct integration into building management, HVAC and monitoring systems.
The display shows the current temperature and relative humidity values directly at the installation site. Display brightness can be adjusted remotely via a Modbus register, including the option to turn the display off.
Use with Perseus
For installations with HWg Perseus devices, RTU-HTemp Display supports automatic sensor detection and variable configuration using the UNI3 extension. This reduces installation time on site.
Installation options
RTU-HTemp Display has a plastic case that allows changing the LCD screen orientation along with the sensor probe. This sensor has a bracket for screw montage. LCD screen brightness can be controlled by a variable in Perseus.
