If fitted, Room Sensors are used to provide Demand Control Ventilation based on the environmental parameter they are measuring.
Below their lower threshold they have no effect on the ventilation rate; once the lower threshold is exceeded the fan speeds proportionally
increase from Speed 2, Continuous until the upper threshold is reached when the fans will be running at Speed 3, Boost. In addition to the
%RH and CO
2
sensor detailed above Air Quality and Temperature Room Sensors may be fitted. With any Room Sensor the range of Demand
Control Ventilation will be dependant on the individual sensor’s characteristics and the thresholds configured by the installer.
