Troubleshooting

The fan will adjust its speed in direct correlation to changes in humidity. This may only be a small amount, depending on the location of the source of humidity and the rise in humidity. It will also depend on the temperature in the room and in close proximity to the fan.

If the fan is close to a heat source, it may take longer to track humidity. Also, ensuring the fan is regularly maintained and cleaned will ensure optimum performance. Poor installation or excessive ducting, incorrectly installed ducting can hinder the performance of any fan. It is important to ensure fans are installed and commissioned correctly.

The fan is designed to run continuously at a controlled low rate. The speed will increase with a rise in relative humidity levels above 65% and or when manually controlled.

To remove the cover, you need to locate the two screws at the base end of the fan cabinet and loosen them until they are clear of the fan case. Pull the front cover away from the lower part and unhook it from the top.

If your fan is noisy, it may be that it is left in a boosted state or just tracking humidity.

Check any manual controls and that the fan is not close to an open window or trickle vent.

General cleaning of the fan can also reduce any noise concerns.

There could be a number of reasons for the fan not running, the first would be to check that the local isolator is not turned off or the fuse in the fuse spur is working.

It would be advised to have a competent person investigate the installation and call our technical team if they require further advice

No, if PIV is installed and set correctly, it should not make a property cold.

The air entering the dwelling will be cooler and feel cooler. However, this air is tempered slightly, mixes with warm air at ceiling height before being distributed around the dwelling. The benefit would be that the system can help improve indoor air quality and potentially help reduce heating demand. It would be recommended to keep all internal doors closed or closed too, in order to obtain the maximum benefits of the system

Some PIV units go into sleep/summer bypass mode when loft temperatures are above 25°C to ensure the system does not contribute to overheating. When the temperature drops back below 25°C (at night), the unit will automatically start running again.

It is not recommended to turn the unit off, turning the unit off for prolonged periods my damage the unit and void the warranty.

Please refer to the running costs section within the website

The best way to check this is with a survey from one of our local specialists who will check whether installing PIV will be suitable and help resolve any current issues.

Items like the size and layout of the dwelling, the suitability of the loft space (if any), and adequate door undercuts will all help to confirm if PIV is a suitable option.

This may be a sign that the unit requires servicing or a filter change.

You may also see signs of a little condensation on windows as the temperature drops in the winter; this should only be for a day or 2.

This could be a number of things, and is normally due to incorrect wiring or the humidity sensitivity being set too low.

If your fan is not extracting, this is normally due to an installation issue.

Excessive amounts of ducting (rigid or flexible), incorrect external terminations or blocked fly screens will all hinder the performance of a ventilation unit.
