What is it and why is it there?

The energiSava® 200 is a centralised heat recovery fan unit that continuously removes stale, moist air from your bathroom, kitchen, WC and replaces it with fresh, filtered air through circular valves mounted in your ceiling and into your living room areas.

The unit also helps to maintain good thermal comfort; ventilation airflows help heat to mix from different sources, so it circulates throughout your home, especially from the central heating system during cold periods.

How will it help?

It will help prevent the build-up of moisture in the house, remove steam/condensation and odours during bathing and cooking, help prevent black mould forming on the walls, behind cupboards etc.

It will also help minimise the dampness that you can get in your cupboards and wardrobes, on your clothes and furnishings, caused by poor ventilation.

It provides continuous, all year round ideal indoor air quality.

How do I control it?

The system operates continuously 24 hours a day at a low rate known as 'trickle', to ensure your home is ventilated at the appropriate level. You can send the system into either 'boost' or 'third speed' in a number of ways to rapidly remove excess moisture or odours. Your unit will automatically control the humidity levels in the home quietly and efficiently.

Remote Control Versions

Press the button once to see the current status of your unit and again to boost the unit. The boost LED will light and the unit will go to boost for 20 minutes. To turn boost off, press the button to wake up the unit and again to turn boost off. If speed three is required, press the button to wake up the unit, press again and once more. The top two LEDS will then become solid. Pressing the button to wake up the unit before pressing again will deactivate speed three. When the battery requires changing, unscrew the switch front cover. The battery is located on the back of the cover. Battery type - 3V Lithium, CR2032.

For further information, see the installation guide.

APP Control Versions

See the separate App instruction booklet. App controlled units allow a large degree of control over the unit via a smart device. For SSID and password information, see the back page of the installation guide, or underside of unit.

Do not permanently turn off the mechanical ventilation systems or block permanent vents. If you feel drafts when the system is running, first check if boost or third speed mode has been turned on, and if needed change this back to normal mode. If you permanently turn off mechanical ventilation systems, your home will be poorly ventilated, causing high humidity and an increase in other indoor air pollutants. Turning off the unit may also damage the system and invalidate the warranty.

Summer bypass

This feature is included as standard and helps to reduce the air temperature coming into the dwelling during the warmer periods. It is an automatic function and operates when the supply air temperature to the property is above 25ºC, reducing the warming of incoming air (from outdoors) by the extracted indoor air.

Staying cool in hot weather

Public Health England cautions that prolonged periods of extremely hot weather pose serious health risks. For guidance about this, please consult the following website, which includes advice on protecting yourself and your dependents: https://www.gov.uk/government/publications/heatwave-plan-for-england

During normal operation, the MVHR unit warms up the outdoor air supplied to the indoors using the warm air extracted from your home. This means the central heating system does not need to supply this part of the overall heating needed for your home, which is likely to decrease your total energy costs compared to other types of ventilation systems.

Warranty

The EnviroVent energiSava® 200 is covered by a full 2-year warranty. You will find the terms of the warranty in the installation guide.

DO NOT switch off the unit - The unit is set to run continuously 24 hours a day, 7 days a week.

DO NOT adjust the ceiling valves - The valves are set to allow a certain amount of air through and should not be adjusted.

Maintenance

More detailed instructions for maintenance are included in the Installation Guide.

Maintenance checks:

These simple actions will help to ensure energy use is kept to a minimum and systems operate effectively.

• Ensure that there is a sufficient amount of air flowing through each of the supply diffusers in the system.
• This Mechanical ventilation with heat recovery (MVHR) system includes air filters that must be inspected every 6 months and replaced at least every 12 months, if air filters are not changed regularly, they will become blocked, which will result in poor ventilation, increased electricity use and noise, and may shorten the life of the fans installed in the MVHR system.

Recommended maintenance schedule:

• Isolate the unit from the mains supply.
• Slide off the front cover (Wall version only).
• Remove the filter caps, replace both filters then reinsert filter caps.
• Engage the mains supply then reset the filter indication by pressing the minus button for 10 seconds.

Filter change indication duration is factory set to 12 months.

Call EnviroVent on 01423 810 810 - Filter part code is FILTER-ESG3.

Not maintaining the filters during the life of the product can invalidate the warranty.
