My DVS is switched on at the control panel, but there appears to be no air coming out of the ceiling diffuser?There could be several reasons for this. The most likely reason (assuming you have an Automatic, Climate Controlled or G3 model) is that the DVS has automatically switched off due to the roof space temperature exceeding pre-set cut-out levels. If this is the case your DVS® will automatically begin operating once the roof-space temperature falls. You should check again in the morning when the roof space is cooler and the DVS should have switched back on again.
If your DVS is still not working in the morning, listen for the fan or check in the roof space whether the fan is operating or not. If the fan is working, check the filter in the roof space as it may be clogged, preventing the DVS from delivering sufficient air through the ceiling outlets.
If the filter is not clogged and the DVS is still not working, please call us on 0800 387 387.
