Filter Service
The filter reminder will appear on the Main Screen when the filter service timer
has counted down to 0 days.
This is a reminder that your filters should be changed or serviced. Please call DVS
on 0800 387387 to arrange for a filter service or replacement filters.
To reset the filter reminder press the up arrow, then OK.
Note: It is recommended that the filters are changed every 12 months in order to
ensure proper operation of the fan and in order to prevent build up of dust, pollen
and bacteria which could be harmful to your health.
Diagnostics
The diagnostic screen (available under the Utilities menu) displays any errors or faults with your
DVS system, as well as current fan speed and RPM (revolutions per minute).
