VENTUS 450+ Manual

1.2 Overview of your System

The VENTUS 450+ is a Home Ventilation System with Heat-Exchanger and Summer Bypass.

Ventilation is achieved by two identical variable-speed fans, one to introduce fresh air into the

house (supply air fan), and the other to extract stale air out of the house (extract air fan). The

two fans provide balanced ventilation of approximately one air change every 2 hours (based

on an average 4-bedroom house. The incoming and outgoing air flows do not mix within the

VENTUS 450+ Unit, but pass in opposite directions through a heat exchanger, so that exiting

warmer air gives up most of its heat energy to the incoming fresh air. The Summer Bypass

function activates automatically or can be activated manually during summer to introduce

cooler air into the house without passing through the heat exchanger.

Fresh air is supplied into the house through insulated Ducting and Side-Entry-Boxes for an even

airflow to vents in each room and stale return air exits via vents usually located in hallways or

other central places of the house.

In automatic mode the System is intelligent and able to sense the need to increase airflow when

necessary by constantly monitoring the internal air quality by measuring CO2 and PM2.5 levels.

The System has Air-Filters to remove impurities in the air and bring clean air into the house and

also to protect the Heat-Exchanger from contamination.

Features of the System

 Efficient German EC-fans with brushless motors

 Heat-Exchanger core from Recair – world leading supplier

 System meets Clause G4 of the NZ Building Code for fresh air ventilation

 Incoming Air-Filter rated to PM 2.5

 High-rated insulated Ducting with Side-Entry-Boxes for efficient and even air distribution

 CO2 and PM2.5 sensors

 HD-Display Controller

 4 operating modes (Auto, Energy-Saving, Haze, Bypass)

 3 fan speed settings

 Weekly timer

 Air-Filter warning

 Wi-Fi capability (currently for maintenance only)

Benefits of the System

 Constant supply of fresh air produces a drier and healthier home

 Constant extraction of moist stale air from the house

 Occupants susceptible to respiratory illness will have a safer living environment

 EC fans are very efficient resulting in low power consumption

 No need to open the windows to vent the house

 No need for window fly-screens as opening windows for ventilation is not required

 Less dust in the house due to filtered air

 Fewer insects within the house due to closed windows

 Increased security due to reduced risk of (a forgotten) open window

 Controlled ventilation also during absence e.g. when on holiday

 Pre-warmed fresh air supply due to heat exchanger technology

 Summer Heat-Exchanger bypass option for cooling the house with fresh air from outside

(No need to leave windows open during hot summer nights)

 Side-Entry-Boxes deliver a more even airflow through the air supply vents

VENTUS 450+ Manual

2 System Environment Requirements

Please read the following advice and recommendations carefully.

To follow them is essential to keep you safe and ensure performance and a long

lifetime for your System.

2.1 Installation, modification, repair

Installation, modification or repair must only be performed by a Solutionair authorised Service

Technician.

2.2 Operating conditions

The VENTUS 450+ is designed to operate in most of New Zealand’s weather conditions. However,

if the conditions are outside the below stated operating range, we recommend to switch off the

System until the weather stabilises back to within the parameters.

Operating range: Outdoor Temperature -25°C to +40°C

Humidity 0% to 100% RH

Sea spray can affect the lifetime of the System and void its warranty. We do not recommend to

use the System in houses which are exposed to sea spray or similar corroding substances like high

sulphur atmosphere environments.

2.3 Vents

All Vents (outlets and exhaust vents, inside and outside of the house) must be clear of any

obstacles within 500mm around the opening.

2.4 HD-Display Controller environment

We recommend to wall-mount the HD-Display Controller in a central place of your house, e.g.

the hall way. To ensure good readability and a long lifetime of the HD-Display Controller, it

should not be exposed to direct sunlight.

Ensure that the environment of the HD-Display Controller is dry and not below 0°C and not

above 45° C.

If you need to clean the HD-Display Controller unit, use a clean damp micro fleece. Do not use

cleaning products.

2.5 VENTUS 450+ environment

The VENTUS 450+ is designed to be installed in your roof space. The environment must be dry and

not below -25°C and not above 80° C.

Do not place any items or loads on top of the VENTUS 450+ Unit. Keep the unit and its

connections free of any other obstacles.

2.6 Ductwork

The Ductwork (which includes Ducting, Plenum and Side-Entry-Boxes) is carefully installed to

ensure the best performance for your System. Do not modify the installation. If you require any

modification, please contact our Service Centre.

Do not place any items or loads on top of the Ductwork. Keep the Ductwork and its connections

free of any obstacles. Bends or kinks can cause loss of performance or may damage the VENTUS

450+ Unit.

VENTUS 450+ Manual

2.7 Electric

Be careful around all electric cables incorporated in the System! Do not perform any

modification!

If you damage a cable by accident, immediately switch off the main power supply and contact

our Service Centre.

The VENTUS 450+ Unit is plugged into a standard 230V socket and can be unplugged if needed.

Make sure you turn off the System at your HD-Display Controller first.

Note: After a power blackout the System stays on stand-by for reasons of safety until you restart it

on your HD-Display Controller.

3 HD-Display Controller

The System is turned on by touching the on/off button in the middle of the HD-Display Controller

screen. Once on, the screen displays the Home Screen:

3.1 24-hour Graph

Tap anywhere within the light blue field to see the 24 hour record of PM2.5 and CO2.

Switch between PM2.5 and CO2 graph by taping the buttons on the right.

PM2.5 sensor - This measures particulate matter (PM) which is smaller than 2.5µm (like dust or smog)

in µg per m³. The PM level is an indicator of the amount of ‘dirt’ in the air.

CO2 sensor - This measures carbon dioxide molecules in parts per million. CO2 rises when people

use air over a period of time. Fresh air contains less CO2 and more oxygen.

may want to increase or decrease the months set

for the replacement cycle.

VENTUS 450+ Manual

3.4 Operating Mode

The System has five operating modes to choose from. By tapping on the current mode symbol, you

can skip through the different modes:

Automatic The Automatic mode sets the fan speed automatically in accordance

with the setting under ‘Automatic Setting’ for CO2 and PM2.5 level

(see ②Setting Menu).

The Heat-Exchanger is engaged and only bypassed when the indoor

temperature is higher than the outdoor temperature and the outdoor

temperature higher than 20°C. When the Heat Exchanger is

bypassed, no heat or cool transfer takes place.

Energy Saving On Energy-Saving mode the Heat-Exchanger is permanently

engaged to help to retain heat or coolness inside of your house. In this

mode you can select the fan speed manually.

Bypass On Bypass mode the Heat-Exchanger is permanently disengaged by

bypassing the incoming air to help you to cool your house with cooler

air from outside, for example during summer nights. When the Heat

Exchanger is bypassed, no heat or cool transfer takes place. In this

mode you can select the fan speed manually.

Haze removing The Haze removing option allows stale air (or also warm air) to be

removed from the house quickly. The Supply Air fan will run at full

speed and the extract fan at a lower speed. For example, if you burnt

the toast and wanted the air out of the house quickly, select Haze

Removing and open a couple of windows.

Sleeping On Sleeping mode the unit reduces the noise to a minimum and sets

all fans to low speed.

4 Right amount of ventilation

Residential ventilation is governed by Clause G4 of the Building Code for fresh air ventilation. The

objective of this provision is to safeguard people from illness or loss of amenity due to lack of

fresh air. It states that:

 spaces within buildings shall be provided with adequate ventilation consistent with their

maximum occupancy and their intended use, and that

 spaces within buildings shall have means of ventilation with outdoor air that will provide

an adequate number of air changes to maintain air purity setting out the provisions for

outdoor air and extract ventilation.

The Building Code recommends 0.35 air changes per hour to meet the provision of clause G4.

Our findings have shown that 0.35 air changes per hour is the bare minimum air volume to keep

a home healthy and that the number of people occupying the home is a key factor in setting air

volumes.

Therefore, the air flow settings of each unit are dependent on its installation and occupancy of

the home. Settings are inputted by the installation technician based on specific calculations

that take into consideration a variety of factors.

5 Care and Maintenance

5.1 Maintenance requirements

If the VENTUS 450+ is not working, do not attempt to open it.

The System must only be serviced by an authorised Service Technician.

The VENTUS 450+ is designed to run continuously without the need to service the fans or heat

exchanger core, provided the filters are changed regularly. However, to gain the best

performance and System longevity, the following basic maintenance work should be performed

periodically, as described below.

5.2 Air-Filters

The VENTUS 450+ Air-Filters are designed to be changed by the owner without the expense of a

visit by a Service Technician. However, if you need assistance, please contact us and book a

Service Technician.

The Air-Filters must be changed at least every 12 months to protect fans and the heat

exchanger from damage and to meet the Warranty Terms and Conditions.

Many Air-Filters may need to be changed more regularly than every 12 months to maintain

optimum airflow and air quality. We recommend to periodically check the Air-Filters every 3

months in the first 1-2 years of using your System. By periodically inspecting the contamination

level of your Air-Filters, which heavily depends on your surrounding environment, you can

determine the ideal time frame of Air-Filter use. You can then set this time frame under ‘Filter-

Setting’ on your HD-Display Controller to remind you of the next Air-Filter change (see 3. HD-

Display Controller -> ③Filter Setting).

VENTUS 450+ Manual

5.3 How to Change the Air-Filters

Always power off the Ventus 450+ with the HD-Display Controller and

switch off the main power before opening the Ventus 450+ Unit!

At the bottom of the front panel of the Ventus 450+ Unit release the two

latches and open the access hatch.

The VENTUS 450+ Unit has an outdoor side (on the left) and an indoor

side (on the right.)

The filter on the outdoor side (left) is an H13 ‘High Efficiency Filter’.

Filter part number: V450-H13

The filter on the indoor side (right) is a G4 ‘Coarse Filter’.

Filter part number: V450-G4

To extract the filters, smoothly withdraw each filter. Each side has two

filters, joined together by tapes so the first filter will draw out the second

filter.

If any debris dislodges from the filter, wipe it out using a clean cloth.

Carefully replace the new filter, taking care that the padding does not

catch as it goes in.

Repeat the process for the filters on the opposite side.

Both filters look similar but they are not the same. If in doubt, check the

label to identify the filters.

If you take out the filters to inspect them, check the label on the filters

and make sure that they go back in the same way.

5.4 How to clean the Vents

The Vent guard can be easily removed by pushing one side of the Vent guard

and turn it 90 degree in its housing to a vertical position. Then gently pull the

Vent guard out of its housing. You may want to hold with your other hand the

housing in place. Put it back in the same way.

For cleaning the Vent guard and housing use just warm water or ph-neutral soap and a clean

cloth. Do not wash the vents in your dishwasher or use harsh cleaning products.

We recommend to clean the Fresh-Air Vent outside every three months, all Air-Extract Vents

every six months and all Air-Supply Vents and the Exhaust-Vent outside every twelve months.

5.5 Use of air freshener and fragrances

You can use your Vents for air freshening liquids and fragrances. Put a few

drops of the liquid on a little cotton ball and place it in the round

indentation in the middle of the vent guard. Only use small amounts of

liquid as oils and alcohols may damage the plastic of the Vent. Never

place liquids directly onto the plastic.
