Product Detail


The wireless room sensor devices of the KYMASGARD® 9000 radio bus system are maintenance-free radio transmitters that function without batteries. Power is generated by a solar cell that converts indoor room light into electric energy. If the ambient light is too low for power generation, the sensors can optionally be powered by two AAA batteries (not included).

These sensors serve to detect the indoor climate and the setpoint values, and to transmit the recorded values to radio actuators and radio signal receivers/gateways by means of radio signals. The following device configurations are available:

KYMASGARD® RFTM-FSE for measuring room temperature and room humidity.

KYMASGARD® RFTM-FSE-ST for measuring room temperature and humidity, and for displaying and setting the temperature setpoint on site using touch buttons.

KYMASGARD® RFTM-LQ-FSE for measuring room temperature, room humidity and air quality (VOC = Volatile Organic Compounds).

KYMASGARD® RFTM-BW-FSE for measuring room temperature and room humidity, and for detecting the movement (or presence) of persons.
