SI-TEMP+HUMEDAD
Temperature and relative humidity sensor with display
Independently controls the temperature and the relative humidity of the air on the premises. Automatically
activates the ventilation system when it detects a temperature or humidity greater than the pre-set value. Once the
environmental temperature or humidity has descended below the pre-set point, the fan remains functioning for a
pre-set period, which can be adjusted by means of the internal clock.

SI-PRESIÓN
Pressure transmission unit
Controls the pressure in facilities with constant pressure ventilation, and transforms it into an electrical signal to
regulate the ventilation system and constantly maintain the same pressure

SI-TIMER
Timer
Adjusts the operating time of the ventilation system to which it is connected. The ventilation system is
automatically activated when the light switch goes on and continues to function for a pre-set time which can be
altered by means of the internal clock
