Vent Axia 409802 “Svara” App Controlled Unitary Extractor Fan – Multi Function
Programmed to cope with the vast majority of installations. The fan is set as default to work continuously at a trickle flow of 10 litres per second. When the fan senses a somebody in the room it increases the flow to 19 litres per second. If the humidity rises rapidly, for example when the shower is on, the fan goes up to maximum flow at 30 litres per second. When the fan senses the humidity level has returned to normal it reverts to the trickle flow of 10l/s. If other settings or functions are desired, they can be selected through the Vent-Axia Connect App which can be downloaded from the App Store and Google Play.
When the light sensor is enabled Svara senses when someone is in the room and then activates. Its sophisticated light sensor is triggered by light movement and shadows. It is possible to set a delay-on so the fan is not triggered by the light during quick night time bathroom visits. The light sensor can also distinguish between headlight flashes from cars and room occupancy, so it is not triggered by passing cars, avoiding nuisance running. The sensitivity of the light sensor can be adjusted via the App.
The light sensor provides an overrun timer but only requires a live and neutral. In houses where there is only a basic fan installed, the home owner can upgrade to a timer fan without having to rewire.
Svara features a humidistat which reacts to sharp changes in humidity, for instance when someone is taking a shower. When set to continuous running, once the humidity sensor is activated the fan runs at 30l/s until humidity returns to normal levels then the fan powers down to 10l/s. Ambient humidity changes will not trigger the humidistat. It is possible to change the sensitivity of the humidity sensor via the App.
Silent scheduling and Automatic cycles
The silent hours scheduling function allows you to deactivate the boost function on the Svara via the App, for example, this would prevent nuisance noise over night. Additionally during a vacation you can set Svara to an airing mode which operates a purge function every 12 hours for either 30, 60 or 90 minutes depending on selection. However, Svaras sophisticated controls, will not purge if the light sensor detects that there is someone in the house.
