The wireles FT room temperature sensor offers all necessary functions and the comfort of a modern device of this kind: transmission of the actual ambient temperature, adjustment of the desired room temperature and, optionally, actual room humidity. The energy required for wireless data transmission is produced by the integrated photovoltaic cell, or the device can be powered by battery. With its neutral white colouring and a height of only 12.5 mm, the room temperature sensor can be integrated into virtually any interior setting.
