Intelligent sensors for <strong>co</strong>ntrolling the fans<br />
Sensors which make it possible to sense certain environmental <strong>co</strong>nditions and automatically start<br />
up the fans. This enables to use the ventilation only when necessary. Using the sensors with the<br />
frequency inverters we can <strong>co</strong>ntrol the regime of operation of the fans, thus preventing the fan<br />
always working at its maximum <strong>co</strong>nsumption. These systems involve a significant energy saving.<br />
SI-PIR-TF-Cenital<br />
SI-PIR-TF-Mural<br />
SI-PIR<br />
Motion detector<br />
Automatically activates the ventilation system when it detects the presence of people<br />
within its radius of action and keeps functioning for a pre-set time, which can be<br />
adjusted by means of an internal clock<br />

SI-SMOKE<br />
Tobac<strong>co</strong> smoke detector<br />
Automatically activates the ventilation system when tobac<strong>co</strong> smoke and other <strong>co</strong>ntaminants<br />
exceed the pre-set value in the sensor and keeps functioning for a pre-set time, which can be<br />
adjusted by means of an internal clock<br />

SI-TEMP<br />
Temperature sensor<br />
Automatically activates the ventilation system when it detects a temperature greater than the<br />
pre-set value. Once the environmental temperature has descended below the pre-set point, the<br />
fan remains functioning for a pre-set period, which can be adjusted by means of the internal<br />
clock. The range of temperature oscillates between +10ºC and 40ºC<br />
