Surface-mounted room sensor for temperature measurement in living rooms, offices etc. Designed for connection to control and display systems. For pre-wiring at the installation site, the back part with the connection terminals can be removed from the upper part of the housing. Optionally, it is possible to add operating elements for controlling HVAC systems.
