• Condensation – clears any extra
condensation that may have been
trapped behind closed curtains etc,
with extra boost of air into house.

purges cavity air in the early evening,
bringing in cooler air earlier thereby
reducing the temperature of the
house and roof cavity earlier.
• Clearing odours and smells.

VENTILATION SETTINGS
At dierent times of the year, more or
less air is needed to clear condensation
in your house. Your system uses these
levels when roof cavity temperature
is too cool to heat, but the house still
needs air to get rid of condensation.
Higher levels will bring more cold air
into a house.
A balance is needed between
condensation clearing and reducing
the amount of cold air into the house,
dependant on each house. Adjust
tosuit.
Spring, Summer, Autumn: Lower
ventilation levels (1 – 3)
Winter: Higher ventilation levels (3 – 6)
To activate: turn o system (press
Power button).
Hold the Down arrow for
3seconds or until display is lit.
Press the Power button to adjust
between 1 and 6.
To exit, press the FUNC button.

rooftemperature.
Press the Up and Down arrow
buttons until you see “03”
appearin the roof
temperature.Use the Power
button to adjust from 0 (dim)

complete control of your home
environment. This means you

FAQ
Where can I get more information on my system?
Our customer service team are more than happy to help – give them
acallon 0800 HRV 123 (0800 478 123). If you would like information
onany of our additional products, please refer to our website.
I’ve had my HRV system for a while – why do I have a black ring
around my outlet vent?
In some houses the air passing out of ceiling outlets will cause a static
charge to build up. This can cause household dust inside the room
tobecome attracted to the charge. Simply wipe away the dust ring with
adry cloth, then open the diuser plate of the vent a little further to help
stop this from recurring. If this persists call us to arrange a visit from one
ofour customer service team.
My ‘Replace filter’ light is on, what does this mean?
This icon provides an approximate timeline for your system’s service and
filter change. We recommend that filters are replaced with a new genuine
HRV filter every two years to ensure the performance of your HRV system
isn’t compromised and you continue to get the best from your system.
What do the ventilation levels on my keypad mean?
At dierent times of the year more or less air is needed to clear
condensation in your house. Higher levels will bring more cold air into
a house. A balance between condensation clearing and reducing the
amount of cold air allowed into a house is needed dependant on each
house. Adjust to suit: spring, summer and autumn: lower ventilation levels
(1 – 3). Winter: higher ventilation levels (3 – 6).
My HRV is working great, but I still get condensation occasionally
on some windows – why is this?
Even though your home is now dry, cold or damp weather conditions may
still lead to some misty windows – certainly far less than what you would
have had without your HRV. No system can guarantee zero condensation
but rest assured your HRV is getting you as close as possible.
