Installation is made simple through Svara’s Bluetooth-enabled App allowing you to choose whether to opt for intermittent or continuous ventilation; whether you would like the humidistat to trigger operation or not; and whether the overrun timer is required. No more fiddly switches and jumpers!
When the fan senses somebody in the room it increases the flow to 19l/s. If the humidity rises rapidly, for example when the shower is on, the fan goes up to maximum flow at 30l/s. 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. Functions Light sensor When the light sensor is enabled Svara senses when someone is in the room and then activates it. 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 nighttime 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. Overrun Timer 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 homeowner can upgrade to a timer fan without having to rewire. Humidistat Svara features a humidistat that 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 overnight. 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, Svara’s sophisticated controls, will not purge if the light sensor detects that there is someone in the house.
