The worldwide standard for home and building control Ensuring the perfect room climate – energy-efficiently KNX-capable Symaro sensors for flush mounting, with minimal energy demand and flexible design Demand-controlled ventilation A low CO2 value in the ambient air increases the ability to concentrate and the comfort of room users. The new Symaro™ sensors for flush mounting measure the CO2 value in the air and control ventilation based on demand. This means that only as much fresh air is supplied as necessary. Other influencing factors needed for a comfortable room climate, like humidity and temperature, can also be measured and controlled by the multisensors. Broad range of applications The communicating sensors for flush mounting are especially recommended for areas where people remain for longer periods of time. In addition, they are ideal for rooms where the number of people present varies over time. In combination with the various frames of the DELTA switch program from Siemens, they can be optimally matched with any room design, from classic to modern. High functionality incl. LED display The communicating sensors for flush mounting measure several variables and provide a connection for a second passive temperature sensor. They can also be used as a controller for room temperature or ventilation or to control lighting and blinds. The current status of the air quality can be displayed on a three-color LED display. Thanks to the KNX S-Mode, the sensors can also be easily integrated into building automation systems from different manufacturers. Attractive design for any room application – can be combined with DELTA frames as well as third-party frames Energy savings thanks to fast, highly precise measurement and low energy consumption Higher functionality due to multisensor and integrated control function Sensors have theft protection and no operating elements – ideal for public places like e.g. schools

Application examples Application 1: room temperature control This application is ideal for smaller offices and rooms with only one radiator. The Symaro sensor for flush mounting measures and controls the room temperature and sends the positioning signal via the KNX bus to the valve actuator. In combination with a window contact, the sensor can also identify the current status of a window and transmit it via the KNX bus.
