RTU-HTemp Display is a wall-mounted indoor sensor for measuring temperature and relative humidity. It combines a local LCD display with an RS-485 / Modbus RTU communications interfac, making it suitable for direct integration into building management, HVAC and monitoring systems. The RTU-HTemp 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.

RTU-HTemp Display can be used with Perseus remote environmental monitoring solutions. RTU-HTemp Display supports automatic sensor detection and variable configuration using the UNI3 extension to help reduce installation time on site. The devie has a plastic case and the LCD screen can be orientated to suit the installation format, along with the sensor probe. The sensor has a bracket for screw plate mounting.

The RTU-HTemp Display can be used for indoor or outdoor temperature and humidity monitoring. The device case is IP40 rated for outdoor use. Measured values are shown on the display and transmitted to the system over Modbus RTU. Based on the temperature and humidity data measured, the sensor can calculate the dew point, absolute humidity or specific humidity and operates over a temperature range of -30°C to +80°C.

The RTU-HTemp Display combines a local LCD display with an RS-485 / Modbus RTU communications interface, making it suitable for direct integration into building management, HVAC and monitoring systems.
