Why Ventilate?
Over a year a family can produce as much as 3,500 litres of moisture in the
air inside their home and damp homes are much harder to heat than dry ones.
Why Smartvent?
Ventilating our homes creates and maintains the air quality we need to ensure
that a healthy indoor living environment exists every day.
Many of us are not aware that the well-intentioned energy efficiencies we
introduce to our homes often negatively affect the air quality which can then
compromise our health. In winter, the issue of poor air quality is compounded
further in the simple act of taking every possible measure to retain the
precious heat we generate in an effort to keep the cold at bay.
Insulation solutions make homes easier to heat, however, this can affect the
good ventilation essential for better air quality, no matter what the age of
your home.
In our New Zealand climate, poor ventilation can create the perfect
environment for the ever-present moisture in the air to not just exist, but to
then expose itself as the unwanted condensation, mould, mildew, proliferation
of dust mites and other airborne nasties that can all damage your home and
your health. Indeed, as international research shows, introducing fresh air,
to dilute airborne particles, can reduce the transmission of undesirable
airborne viruses by over 70%.
Employing an active approach to ventilation, which uses a controlled process
to continuously regulate and distribute clean, filtered air throughout your
home, increases the positive benefits of good indoor air quality, to assist
protecting the health and wellbeing of your family.
Almost a third of all rental homes have been found to feel damp.

SmartVent is proudly owned by Simx, a business unit of the Volution Group. As
a leading international designer and manufacturer of energy-efficient, indoor
air quality solutions, Volution Group is committed to providing healthy air,
sustainably. An efficient home ventilation system may well be just a low-cost
product that keeps moisture build-up at bay. An effective system, however, is
an investment that delivers on the quality of life promise we now expect, as
the minimum, for in-home comfort. SmartVent offers a wide range of home
ventilation solutions with systems designed to best suit the specific needs of
any home today.
With up to 69% of your lifetime spent in your home, a comfortable and healthy
living environment is the least you should expect. Filters
The filter is an important component of a ventilation system if it is to
contribute towards a better indoor environment. On average, we breathe in
20-30kg of air every day, so it is essential that the atmospheric particles
that can adversely affect our health, are effectively, and efficiently,
filtered out.
All centralised SmartVent systems feature high grade F7 filters that capture
up to 90% of 0.4 microns particles such as fine pollens, dusts and allergen
from the air making the air cleaner to breathe. High quality HEPA filters are
also available for asthma and allergy sufferers.

Positive Pressure Systems
Outside Air
Fresh air drawn in from outside
Exhaust Air
Moist, stale air forced out of the home
better air = better health
Positive pressure systems draw in fresh air from the roof cavity and filters
it before distributing the clean air into,
and around, your home via a network of ceiling diffusers. The air movement
created forces the moist, stale air that causes condensation, mould and mildew
out.
In winter, good air circulation and home heating are essential for maintaining
air quality. A home ventilation system
from SmartVent reduces the excess damp, moisture-filled air and improves the
overall air quality inside the house, making it much healthier for you and
your family. A good investment for the well-being of your family and the
overall health of your home.
Air Filter
Diffuser
Centrifugal Fan 6 Product Guide www.smartvent.co.nz
Like a cold drink on a hot day, moisture will form when the temperature of the
air drops when it contacts colder glass surfaces. We refer to the warm air
reaching dew point as condensation.
Seasonal Add-Ons
SmartVent Evolve2, Positive+, Positive2 systems can be further enhanced with
the addition of any of the following seasonal add-ons. Heat Transfer and
Tempering Heater operations can be scheduled to maximise convenience. Summer
Feature During warmer months, outside air can be used as the primary air
source for the system, instead of the roof cavity. Keep bugs and pollens out
overnight and bring a fresh filtered breeze in when you need it most. Heat
Transfer During cooler months, excess heat from your heated lounge can be
transfered to your bedrooms. The recycle function is a bonus feature which
allows inside air to be recirculated when outside temperatures are still a bit
too cool. Tempering Heater When it’s cold outside and you want to take the
chill off the incoming air, a 1 or 2kW tempering heater allows you to make the
most of the driest air available.
System Components
SmartVent positive pressure solutions include a range of control options,
backed up by quality components. System operation is, primarily, set-and-
forget. Simply enter your preferred temperature and the system does the rest.
Depending on the model that suits your lifestyle and budget, sensing
temperature alone, or temperature and the amount of moisture present, with or
without seasonal add-ons, there is a SmartVent system for you. Your fully
automated, smart wall controller determines the amount of air required to
ventilate your home while temperatures and moisture conditions change
throughout the day and night. All systems can be manually operated if you want
more control, and the flexibility of scheduling seasonal add-ons gives you
ultimate control of your home environment.

Overview
SV02E2
SmartVent Evolve2 is a centralised positive pressure system that constantly evaluates the environmental dynamics in and around
your home. Four temperature and humidity sensors measure moisture content throughout the home, in the roof cavity and outside,
to calculate dew point which is the measure of when condensation will appear on the windows given the internal temperature and
moisture conditions combined with the temperature of the coldest surface. This comprehensive and clever solution can then determine
how much improved air quality to introduce to effect change without the risk of over-ventilating. Market-leading Evolve2 technology
comes with a range of fantastic features such as flexible upgrade options with weekly scheduling, dew point control, all easily
navigated with the intuitive wall controller. Just set the preferred temperature and the system does the rest.

These recommendations are based on the standard components in the system.
– This selection guide assumes 2.4m stud height, if greater please increase
the square metre size by 4% for every 0.1 metre
(e.g. For a 2.8m stud height, increase your house size by 16%). – If you
choose to exceed the number of rooms listed in the selection guide above, the
performance of the system will be affected. – By adding additional outlets to
the system the available air is being divided amongst more rooms. – Extra duct
may be required depending on the size and layout of the home (see Accessories
on page 54). – For larger homes please contact SmartVent for technical advice
on 0800 140 150.

The Summer Feature seasonal add-on is an optional second air intake located
under the eaves or at the gable end of the home (weatherproof grille maybe
required). This feature provides an alternative air supply for use during
summer months.
– When installed on the south side of the house it ensures the coolest
possible air is used. – If the house design prevents the installation of a
Summer Feature Seasonal Add-On, there are alternative options for a second air
source such as through roof kits. SmartVent have a full range of accessories
available to assist.

Heat Transfer has a motorised damper that operates to switch the air drawing from either the outside or roof cavity to instead draw air from the room where there is a heat source (usually a lounge) and transfer it to the bedrooms. This seasonal add-on can also provide internal air circulation when roof cavity and/or outside temperatures are too cold. When installing a Heat Transfer seasonal add-on, an adequate heat source is required that is capable of delivering enough excess heat to warm rooms it is transferred to, while remaining effective in the source room.
– It is important to point out that when Heat Transfer is activated, the system is not bringing in fresh air, therefore not ventilating the home – however the home is getting the benefit of transferring heat around the house (e.g. cold winter nights). It also shuts off the air supply back into the heat source room.
Note: – Heat Transfer is recommended when there is a heat source that creates excess heat (i.e. wood fire or similar). – A heat pump sized for the room it occupies may not be suitable for Heat Transfer. – If planning to use a heat pump with Heat Transfer, first consult the heat pump installer/manufacturer.

A Tempering Heater is a 1kW or 2kW element inline heater designed to take the
chill off incoming air.
– Specified when the ability to temper the delivered air to a more comfortable
temperature is required. – Tempering heaters will not provide a home heating
solution. – Using a 1kW heater, the temperature of the introduced air can be
raised by up to 8°C. The temperature of the home will not
increase by this much. – A SmartVent system with an inline tempering heater is
not intended to be a substitute for an effective heating system in the home.

Heat & Energy Recovery Systems
Exhaust Air Moist, stale air
forced out of the home
Outside Air
Fresh air drawn in from outside
Supply Air
Tempered air enters the home
Return Air
Moist, humid air is extracted from the home
better air = better health
Heat recovery systems recover heat or cooling energy from extracted room air
and also heat energy from moist air areas such as bathrooms, while energy
recovery systems recover the heat or cooling energy from extracted room air
only. Both systems draw fresh air into the home primarily from outside while
simultaneously extracting moisture-laden, stale air from inside the home. This
simultaneous process is referred to as a balanced system.
Being balanced, the systems are able to use the warmth of the extracted air to
temper the clean incoming air as the two airflows pass by each other without
the clean incoming air being polluted. The clean air is then distributed in,
and around, the home via ceiling diffusers, giving your home a breath of fresh
air and more comfortable indoor living conditions.
In winter, it is just so much more important that ventilation systems not only
perform their basic function of extracting moist, stale air, but do it in such
a way that complements the costly efforts made to warm the home in the first
place. A home is not going to remain comfortable and cosy if the “efficient,
low cost” ventilation option just brings in a constant flow of cold air from
the outside. System performances are best measured by the efficiency of the
core. Synergy2 models, with a cross-flow core, deliver up to 75% efficiency.
Balance models, with a counterflow core, deliver up to 90%.
Modern homes are significantly more airtight than older homes, meaning
moisture build up is more likely to happen … and faster
Seasonal Add-Ons
SmartVent Synergy2 systems can be further enhanced with the addition of any of
the following seasonal add-ons. Heat Transfer and Tempering Heater operations
can also be scheduled to maximise convenience.
Second Air Source While standard heat/energy recovery solutions draw air
directly from outside, a second air source kit allows air to be drawn from
either outside or the roof cavity, allowing you to take advantage of any solar
gain, automatically.
Heat Transfer During cooler months, excess heat from your heated lounge can be
easily transfered to your bedrooms. The recycle feature is a bonus as it can
be used to recirculate inside air when the outside temperature is still a bit
too cool.
Tempering Heater When it’s cold outside and you want to take the chill off the
incoming air, a 1 or 2kW tempering heater allows you to make the most of the
driest air available.
System Components
SmartVent heat and energy recovery solutions deliver filtered fresh air into
your home, via an energy or heat recovery
core combined with powerful centrifugal fans. System operation is, primarily,
set-and-forget. Simply enter your preferred temperature in the home and the
system does the rest. Depending on the model that suits your lifestyle and
budget, sensing temperature alone, or temperature and the amount of moisture
present, with or without seasonal add-ons, there is a SmartVent system for
you. Your fully automated, smart wall controller determines the amount of air
required to ventilate your home while temperatures and moisture conditions
change throughout the day and night. All systems can be manually operated if
you want more control, and the flexibility of scheduling seasonal add-ons
gives you ultimate control of your home environment. The Balance and Tempra
deliver the latest in energy efficient EC fan technology. SmartVent Balance
systems include a core bypass to allow outdoor air to be introduced, in warmer
months, without being tempered by the hot outgoing air as would normally be
the case. Keep bugs and pollens out overnight and bring a fresh filtered
breeze in when you need it most.

Overview SmartVent Synergy2 is a centralised energy or heat recovery system that constantly evaluates the environmental dynamics in and around your home. Four temperature and humidity sensors measure moisture content throughout the home, in the roof cavity and outside, to calculate dew point which is the measure of when condensation will appear on the windows given the internal temperature and moisture conditions combined with the temperature of the coldest surface. This comprehensive and clever solution can then determine how much improved air quality to introduce to effect change without the risk of over-ventilating. At the heart of these systems the exchange of heat energy from the outgoing air to the incoming air provides an excellent solution for homes built after 2002.

Overview SmartVent Balance is an energy efficient heat recovery ventilation
system designed specifically for new build and low-permeability properties.
These systems incorporate MVHR (mechanical ventilation with heat recovery)
technology which effectively uses the heat of the stale air being extracted to
temper the incoming cold air to ensure that the loss of heat in the home is
kept to a minimum. The warm, moist, stale air is extracted from a central
point in the home, such as the hallway or wet rooms, through ducting and
passed through the heat exchanger before being exhausted to the outside.
Incoming fresh air is filtered and then tempered, without being polluted, via
the integral counterflow heat exchanger which recovers up to 90% of the heat
energy from the home, that would otherwise be wasted, thus maximising energy
efficiency. A built-in core bypass allows for effortless summer operation,
this European-inspired and manufactured system is set to impress those looking
for the best.

Heat Transfer has a motorised damper and external fan that operates to switch
the air drawing from either the outside or roof cavity to instead draw air
from the room where there is a heat source (usually a lounge) and transfer it
to the bedrooms. This feature can also provide an alternative air supply. When
installing a Heat Transfer feature, an adequate heat source is required that
is capable of delivering enough excess heat to warm rooms it is transferred
to, while remaining effective in the source room.
– It is important to point out that when Heat Transfer is activated, the
system is not bringing in fresh air, or extracting stale air, therefore not
ventilating the home – however the home is getting the benefit of transferring
heat around the house (e.g. cold winter nights). It also shuts off any supply
back into the heat source room.
Note: – Heat Transfer is recommended when there is a heat source that creates
excess heat (e.g. wood fire or similar). – Heat Transfer can also be used to
manage the preferred temperature and moisture conditions in the home when
added to
a SmartVent Synergy2 system. – A heat pump sized for the room it occupies may
not be suitable for Heat Transfer. – If planning to use a heat pump with Heat
Transfer, first consult the heat pump installer/manufacturer.

A Tempering Heater is an element in line heater designed to take the chill off
incoming air.
– Specified when the ability to temper the delivered air to a more comfortable
temperature is required. – Tempering heaters will not provide a home heating
solution. – The temperature of the introduced air can be raised by up to 8°C.
The temperature of the home will not increase by this much. – A SmartVent
system with an inline tempering heater is not intended to be a substitute for
an effective heating system in the home.

SmartVent Evolve2
SmartVent Positive+
Q. Can existing SmartVent Positive Pressure systems be upgraded to SmartVent
Evolve2?
A. Yes. Product code FAN6990.
Q. What are the main differences between SmartVent Evolve and the new
SmartVent Evolve2?
A. SmartVent Evolve was operated by a wireless device connected to the ceiling
control box via either the supplied router or the customers own internal Wi-
Fi.
SmartVent Evolve2 comes with a touch screen wall controller, connected via a
cable to new generation sensors and hard-wired to the control box housed in
the roof cavity. The SmartVent Evolve2 control system also has increased
functionality, giving more control than ever before to end users.
Q. Is there any difference to the duct and grilles, or generic kit contents
for SmartVent Evolve2?
A. SmartVent Evolve2 models have the same base components that are available
in other SmartVent models of the same series, i.e. the base components for
SV04P2 (quantity and quality of duct, grilles, branch take-offs, diffusers
etc.) are the same for SV04E2.
Q. What are the features of Evolve2?
A. SmartVent Evolve2 includes features such as: Air source and in-home
temperature and humidity sensing – four combination temperature and humidity
sensors are located in and around the home – the roof cavity, outside, living
area and one bedroom. This unique combination of sensors measure dew point,
which is also known as the point condensation will form on cold surfaces.
Indoor dew point indicator – for the two rooms with sensors, showing the
condition of the room selected (lounge or bedroom) Auto-Ventilation mode – the
system chooses where to draw air from and at what speed depending on indoor
dew point and temperature levels – in that order. The lounge and bedroom
moisture levels have the highest priorities in dictating the fan speed,
followed by temperature. Timer-Ventilation mode – allows user to schedule air
source and fan speed over four time periods on any day. This feature allows
programming for singular days of the week or multi-selection of days for added
convenience. Manual-Ventilation mode – allows user to manually control fan
speed and air source. Boost mode – allows user to increase to high fan speed
for twenty minutes. Also known as `burnt toast’ setting. Keylock – allows
users to lock the screen so settings cannot be accidentally changed. Timer

into effect. The G4 Building Code covers the now mandatory extract ventilation
requirements for bathrooms and kitchens and the updated AS/NZS standards
provide the latest guidelines for internal wet area zones in general. In
addition, the Healthy Homes Standard makes it a requirement to fit extract
fans in rental properties.
Filters
F7 Filter SmartVent high grade F7 filters capture 80 – 90% of fine pollens,
dusts and allergens from the air are included with all systems, making the air
cleaner to breathe. All SmartVent systems come standard with an F7 filter.
F7 Filter with Carbon If there is concern about smell from the roof cavity,
outside, or from the fire if heat transfer is installed. Carbon filters remove
odours. Note: Carbon filters will reduce the air flow through the system.
HEPA Filter with Carbon A high quality HEPA filter is available if required,
for families with asthma and allergy sufferers. Note: HEPA filters will reduce
the air flow through the system.
G3 Filters SmartVent Synergy2 and Balance systems have two primary G3 filters
installed, as standard, to protect the core from debris build-up.
Periodically, these filters will need to be maintained/cleaned. Replacement G3
filters are available as a spare part. Contact SmartVent on 0800 140 150 for
assistance.
Diffusers The diffusers are flat so therefore distribute the air across the
ceiling and down the walls and windows to help reduce condensation. As a
result the air is distributed further around the room. Note: Diffusers are
adjustable to allow balancing of airflow delivery for each room.
Heating Systems Pellet fires, wood fires, electric heaters or heat pumps
Portable LPG gas heaters or un-flued fixed gas appliances
Un-flued gas appliances of both kinds release large volumes of moisture into
the air the entire time they operate. This can result in condensation levels
being higher and also make the moisture content in the air difficult to treat
with a ventilation system. We recommend homeowners use different forms of
heating. Gas appliances with a flue are acceptable because they expel moisture
externally. Note: – Heat transfer should only be specified when there is a
heat source
that creates excess heat i.e. wood fire or similar. – A heat pump sized for
the room it occupies is not suitable for heat
transfer. – If planning to use a heat pump with heat transfer, first consult
your
heat pump installer/manufacturer.
Heat Trans Systems If the home already has a Simx HeatTrans system installed
you have three options: – Re-use the duct and diffusers and install a
SmartVent Positive
Pressure system with a Heat Transfer seasonal add-on incorporated. – Re-use
the duct and diffusers and install a SmartVent Synergy2 system to replace a
HeatTrans system – Upgrade older models of HeatTrans with a touchscreen
controller (FAN7194).

Installation Guidelines
House Size
The first step when specifying a SmartVent system is how many square metres
the home is excluding the garage.
A secondary (but just as important) factor is the stud height. The square
metre (m2) used in the selection charts is based on a stud height of 2.4m.
Moisture ventilated into roof cavity increases the risk of condensation in the roof cavity
House Layout
The layout and orientation of the home, the way it is heated, as well as the
construction all have an influence on the system to specify.
Note: Use graph on the last few pages of this guide to map your layout. Plan
where the outlets will be placed in each room.
Two Storey Houses
Access to lower floors can be achieved through cupboards, wardrobes and other
voids.
Consider increasing the size of the kit specified if there is more than one
duct run required to a lower floor.
It is better to specify a larger or two-fan system particularly if the ground
floor is concrete block with aluminium joinery and/or a large area. See page
21 for additional fan options.
Open Cavity Walls
There are three general classifications for wall cavity systems. A drained and
ventilated cavity separates the cladding from the wall by a cavity that is
vented at the top and bottom and detailed to allow water to drain from the
base of the wall. Open rainscreen walls follow a similar design, but without
deliberate openings at the top of the cavity. A drainage plane separates the
cladding from the inner wall by a narrow cavity of only a few millimetres
thickness that is only intended to drain water from the back of the cladding.
Brick veneer is the most widely used drained and ventilated wall type in New
Zealand, with a sound history of managing water leakage. Recommendations for
cavity depth and ventilation opening sizes vary little between standards and
the practical literature on design and construction, with minimal change to
the systems underlying principles.
A typical eave detail allows the wall cavity to open into the roof cavity (see
below). Considering the purpose of the wall cavity is to remove moisture by
using air to transport it away, it stands that air vented into the roof cavity
increases the risk of moisture -related issues in roof spaces.
Large amounts of moisture can enter the roof space,particularly when the wall
cavity is subject to excessive wetting from poor window flashings or non-
sealed façade materials. Protecting the structure from moisture has always
been one of the primary goals of product manufacturers, builders and
practitioners. Buildings are not perfect, leaks still occur, and the role of
drying is very important to the moisture balance.
Typical examples of NZ homes with open -wall cavities
Usually described as a 1950 or 1960’s brick home, these types of homes are
very common throughout New Zealand. A quick on -site check is all it takes to
identify whether this is the case. 1. Identify whether the home is on piles.
2. Yes its open-wall cavity you need to assist your customer to
understand the next steps
3. No its on a concrete base usually you are ok to specify a standard
system
If the home is on piles it is unlikely a positive pressure system drawing air
from the roof cavity will be a practical addition to the property. You have
the following options: 1. Always install a vapour barrier to cover the ground
under the
home (regardless of other recommendations you make, this is critical to
moisture control) and, 2. Install a SmartVent system drawing directly from
under the eave (no roof cavity intake) and,
3. Add an optional 1kW or 2kW tempering heater.

Installation Guidelines
Unvented Appliances
Unvented range-hoods, bathroom extraction fans and clothes dryers not only
fill the roof cavity or home with moisture, they may not be compliant with
current building regulations. If you are installing any ventilation system
into your customer’s home, you should also recommend the homeowner duct these
appliances to the outside.
Roof Cavity and Access
Ensure you have enough room to install the system and access it for
maintenance. Note any areas you may not be able to access (i.e. flat roof,
lower floor rooms), be aware of any potential problem areas and discuss these
with your customer.
A minimum of 500mm is recommend to fit SmartVent positive pressure systems.
Note: Check the dimensions of the product to ensure access to the roof space
is available.
Supply Outlets and Return Air Supply
SmartVent supply outlets should be placed in your living areas and bedrooms,
ideally in a central position. If necessary to offset do so on the window side
of centre.
Place the supply outlets at least one metre from any vertical surface (wall)
and away from the entrance to an ensuite or bathroom. In a living room try to
install a supply outlet near the centre of the room.
A centrally placed supply outlet in the hall is not recommended as there is no
guarantee the occupants of the home will keep the bedroom doors open overnight
or that sufficient amounts of air would enter the bedroom, which are areas
where condensation is often a problem.
Under ideal conditions, supply air to the perimeter of the home and extract
from the centre. Consider the overall airflow pattern.
SmartVent Synergy2 and SmartVent Balance return air vents should be centrally
placed in the home for maximum benefit.
Ducting Runs
Once you have decided the supply outlet locations, connect ducting to the back
of the diffuser, then work towards the centre of the home to ascertain a
central position for the fan, preferably above a utility room, bathroom or
similar. Positioning the fan above bedrooms is not recommended.
Note: Avoid long duct runs by placing the fan centrally. – Longer duct runs
should have fewer supply outlets. – The highest percentage of air should go
through the longest
duct run – adjust diffusers to suit. – Two duct runs in parallel will move
more air than one long run. – The more duct and bends, the less air that will
be delivered
into spaces. – The longer the duct run the more resistance against the fan
and the less air will be delivered to the home. – Install duct fully extended.
Do not install in
a compressed state. – Cut out excess duct and avoid unnecessary bends.
52 Product Guide www.smartvent.co.nz
Ducting Joins Double tape every join in the duct and always use a duct joiner
to join two lengths of duct. Note: If you do not use a duct joiner the duct
may collapse over time and the join may separate. This is a common fault in
installations and the simplist to get right. Be sure to correctly pull down
the blanket insulation and double tape a join.
Ducting Support Hanger or saddle material in contact with the flexible duct
shall be of sufficient width to prevent any restriction of the internal
diameter of the duct when the weight of the supported section rests on the
hanger or saddle material. Flexible duct may rest on ceiling joists or truss
supports. Maximum spacing between supports should not exceed 1.5m.
Ducting Branches – Y-branches will split the air 50/50. – DBTO (Double Branch
Take Off) will split the air relative to the outlet sizes. If a DBTO is used,
ensure the central take-off is used to where the most air is required. Note:
When you add branches or extension kits to the system try to ensure duct runs
are of similar lengths.
Extract Heat Transfer Do not place the intake less than 2 metres away from
the flue, in order to protect the fan motor from high heat. Place the Heat
Transfer intake across the room from the heat source to ensure heat travels
across the room prior to being extracted.
SmartVent Evolve2 Systems One of the sensors must be in the heat source room
The wall controller does not need to be located in the heat source room.
SmartVent Positive2 and Positive+ Systems The wall controller must be in the
heat source room.
Non-Standard installations SmartVent can recommend solutions (e.g. roof kits,
low profile ducting) for unusual installations.
