We have collated a range of frequently asked questions.
Which window styles are suitable for Ventus Automated Hardware?
A wide range of window types can be catered for, including:
- Louvre window/ louvre gallery
- Awning, casement windows
- Servery awning windows
Do you require an electrician to install the system?
No, the easy to install system runs on a 24 volt ‘plug and play’ system using quick connect plugs and leads. A transformer/power supply reduces power from 240V AC to 24V DC so it’s safe to configure.
You will need a 240V AC mains GPO that must be installed by a licensed electrician, and it is recommended to have one installed in the same access area as the controller, or at least accessible by the controllers power supply.
How many windows can operate on the one system?
Each system has five channels, and up to 100 controllers on each – this means the system can handle the most complex of installations.
Is the system difficult to configure?
No, step-by-step guides are available to walk you through the installation process.
Can you retrofit existing openings?
- Louvre Gallery can retrofit into an existing opening
- Automated Chainwinder can be retrofitted to an existing installed awning window
As long as the windows are true and square, there is a electric solution for the opening. Step-by-step guides show you how to get the job done.
What warranty does the system have?
Six years for the hardware, in line with the standard Doric Products warranty, and one year for the electronics.
How many louvre blades can Ventus handle?
- 102mm Series: 27 louvre blades, gallery height of 2,420mm
- 152mm Series: 17 louvre blades, gallery height of 2,471mm
Does the system work with unusual size openings?
Yes, but the opening must be square, as louvres can be adjusted for different shape spaces.
Each order offers customisation.
What level of experience is required to install the system?
No specialist experience is necessary.
How is the system controlled?
RF transmitters, wall mounted controls or handheld units are what is available from Doric. A building Management System “BMS” can also be used if desired.
How can the automated function of the system be utilised?
The system can be programmed to function individual windows, or multiple windows, across a range of parameters from different controllers, living areas, floors, or groups of windows.
Can you integrate air conditioning into the system?
Yes, the Ventus Automated system is smart home compatible, complete with light, temperature and humidity sensors.
How can the system improve the energy efficiency of a house?
Ventilation reduces the load on air conditioning, as the system “allows the breeze in”. By allowing passive ventilation, there is no need to run a fan, air conditioner or air pump, thus saving on power usage.
How secure is the system?
From a traditional home security standpoint, the system is as safe as the traditional, non-automated hardware. Electronically, the RF coding is very similar in nature to other traditional remote-control fixtures, such as electric garage doors and Television remotes meaning that the system is very secure.
What are the advantages of the system?
Ventus allows windows to be opened that are often hard to reach but are in the ideal location to improve airflow. Opening and closing these windows automatically controls heat, moisture, humidity, disperses organic compounds, such as gases from cooking, which ultimately reduces triggers for conditions such as asthma, making for a more liveable home.
What is Ventus Plug and Play?
Plug and Play is a DC 24V cable and controller kit use to supply power to Ventus Automated products. Components are manufactured to all work together as a kit to ensure that all connections within a building are easily joined and connected correctly (+/- to +/- ). This assists in fast hassle-free installation and at worst simplified fault diagnosis.
When isn’t a plug used?
The only cable connection that doesn’t have a “plug” as a connection is at the controller. If an issue presents this is the first and often the only check required if a window does not operate.
“My electrician uses his own cables.” Is this under warranty?
No, the cables in the “plug and play” system are specifically designed to match the winders and actuators in the Ventus system.
Will other cables work?
Yes, Figure 8 cable will work however we do not guarantee or warrant this. Using other cables may result in the windows operating at different speeds. Using Plug and Play cables means all the operators work at the same speed and there will be no damage done to the motors.
What do electricians do if they need to draw a cable or cables through a void that is small and don’t want to be inhibited by the plugs?
The Plug and Play system has cables that are plug on one end only. The end of the cable can then be drawn through the void or cavity.
Why are cables only 3 meters long?
The cables are 3 meters because the winder or louvre also has a length of cable attached and this increases the 3 meters. In most cases this is sufficient to connect to a window to the controller.
If longer cables are required there is a “C2075FM3” cable that is a 3 meter Plug and Play extension.
Where do I put the controller?
Every installation has an “ideal location”. The ideal location is “the average distance between the windows to be powered where all cables are the same length. Put the controller there and run an extension cord from the GPO to the controller.
What’s an example of poor installation?
Wiring in the controller in and running long cable runs to each motor. Sometimes this is unavoidable but should be avoided. A 10A Power upgrade is available in this application.
When do you use a 2.5A power supply and when do you use a 10A power supply
The 10A power supply is best used in commercial jobs, when a TCE300 or LCD300 awning winder is used to run more than 4 windows off one controller and in locations where windows are on longer than 9-meter cable runs or if cable lengths are different by more than 30%.
So why use a 2.5A?
The 2.5A is sufficient for louvres and the small SCE300 awning winder to power up to 8 windows with short cable runs. The 2.5A power supply should really only be used in residential applications. There is a chance when using only 2.5A power supply issues may arise with slow window speeds and windows not opening if the power is insufficient or inconsistent.
What else can be done to make installation and potential troubleshooting easier?
Putting in an access panel to get to the controller in the event of an issue saves climbing through the roof cavity to access the controller if a fault eventuates.
What cable does the Wind Light Rain sensor use?
The WLR001 uses the C4075M3 as the extension. Order is Blue, Black, Brown, Yellow, from left, from the middle of the controller.
How do I choose what windows and how many controllers I will need?
Divide the windows to be controlled into elevations, levels, or zones. For example, North, East, / Level
What controllers are available?
Controllers are either single controller or 8 Channel controllers. This means “single controls “one window” and “8 channel
How do I calculate the cables?
Using a bank of 5 windows with an average distance of “for example 7 meters”. Use three 3 meter cables per window and add 20%. This allows for corners and offsets. The answer is 15 ( 5 x 3 = 15, plus 3 20% means you require 18 cables.
What cables are available?
Cables are all 0.75mm gauge in 2 or 4 core. Plugs are either male or female in 2 or 4 cores. Plugs are only able to be connected one way. Ventus cables are soldered, thermally welded, and sealed with silicone gaskets to ensure they cannot be installed incorrectly and are waterproof.
Which way do cables go?
The Male end of the plug is always the power supply and the female end receives the power form the male plug.
How long a distance can a cable be and why?
Cables have resistance. The longer the cable the more power is lost, more load is put onto the power supply and if the power to the motors is reduced the slower and less powerful the motor will be.
Can I have longer cables than 3 meters?
Yes, but these are special order and we can help optimise the cabling in circumstances where long runs are required, Often long runs can be avoided as it is better to either find a GPO (power) closer to the window bank, or run an extension lead from the GPO to the AC transformer This means there is only one lead running a long distance. It’s better to run 240v further then step down.
Why don’t you do 240V AC and run a signal wire and a daisy chain in series cable layout?
Adding another component such as a third wire into an installation now requires a builder an electrician to be working on the system for a long period of time. There is also architectural considerations such as getting around areas such as stairwells, air conditioning ducts, insulation, on so on. Doric Ventus puts the power where its needed and locates the Controller via remote.
Why can’t I have the controller in the living area?
You can, but why would you? Once paired when installed and a test run is completed the system is now paired until such time as another window or transmitter is required to be added.
The owner likes hardwired installation is this more reliable?
No, Modern RF transmitters are extremely reliable. It is the same technology as found in television controllers and garage door operators. We don’t run cables in these applications so why would we for a window?
Can I have a hardwired installation?
Yes, it can work in this way. This is sometimes a requirement in a school or government installation.
Can a smoke alarm be connected to the system?
Yes, there are many considerations. Power to open? Power to close? Battery backup?
Can Doric Ventus integrate with a BMS system?
Yes the simplicity of 24V DC current means that the BMS is now the sender of the signal to the channel controller, and the channel controller becomes the power transmission and the sender of this signal to the window.
When do I need a battery backup?
A battery backup is a feature installed when the building requires control of the windows when/or if their is a power outage.
What if my window moves and stops?
The operator is detecting friction or assist the sash or louvre by hand to move to the open position until you can get enough room to disconnect the sash plate. Cycle the sash in and out and look for resistant If significant resistance if present rectifies or call your fabricator. An installation issue is present.
What if my window doesn’t move at all?
Disconnect the operator from the window sill by undoing the screws on the bracket that mounts the operator to the frame. Cycle the window in and out and check for resistance. If present there is an installation issue.
What if there is no power?
Check the connection at the controller and make sure it is powered on.
What if this doesn’t work? Turn off the transformer power supply at the GPO. remove the power supply and contact your Doric Sales Rep.
