Breezway PowerlouvreTM System

Automated Louvres
The award winning Altair® Powerlouvre™ Window displays pure elegance with no visual indication of any external rods or automated device making this product a stylish option for contemporary residential or commercial building designs.


Superior aesthetics with low voltage motors concealed within the frame and no unsightly control rods.


When designing your building consider the way you operate your louvre windows within reach or up high.


Easily operate with a touch of a button, or automatically in anticipation of needs, not in response to them.


Operate Powerlouvres up high more frequently by removing the need for awkward map rods to operate manual handles.

Powerlouvre App Operation

The *Apptivate Control Unit includes a Bluetooth Smart module which allows wireless communication between the Apptivate Control Unit and a compatible device running the Powerlouvre App.

*Please note: The Apptivate Control Unit is temporarily unavailable to order. We recommend operation by bell press switches or through a building management system.

Compatible devices

Compatible devices will have Bluetooth Smart modules installed and have an iOS or Android operating system. Devices include:

Apple products running iOS 7 or newer:

  • iPhone 4s and newer
  • iPad 3 and newer
  • iPad Mini and newer
  • iPod Touch 5

Devices running Android 4.3 and newer, including:

  • Samsung Galaxy Range
  • HTC One, MAX
  • Sony Experia Range
  • Droid RAZR, Ultra, Maxx, Mini
  • Google Nexus 4, Nexus 5, Nexus 7 and Nexus 10


Establishing associations between the Powerlouvre App and Apptivate
Control Units requires:

  • Close physical proximity between the Powerlouvre App and the Apptivate Control Unit, and
  • An access code (defined by the first Powerlouvre App to be associated to the Apptivate Control Unit).

If the Access Code is forgotten, a factory reset button can be activated by snapping off the front cover plate of the Apptivate Control Unit and pushing a paperclip through a small hole to hold a button down for a brief period. Security will be maximised by positioning the Apptivate Control Unit in a location that restricts unauthorised access.

If restricting access to the Apptivate Control Unit is not practical then users can seal the hole to block access to the factory reset button from the front panel necessitating the unscrewing of the Apptivate Control Unit from the wall in order to carry out a factory reset.

Automatic operation in response to temperature

Temperatures can be set at which the Apptivate Control Unit will:

  • Automatically open the windows to naturally cool the room, or
  • Automatically close the windows to retain warmth within the room.

Automatic response to temperature can be enabled or disabled:

  • Remotely from the Powerlouvre App, or
  • Directly on the Apptivate Control Unit.


  • As the temperature sensor will be located within the wall cavity it may be susceptible to environmental conditions so the temperature readings will be indicative of the air temperature within the room, but will not exactly reflect the air temperature within the room.
  • When responding to temperatures both channels of Dual Channel Apptivate Control Units will respond simultaneously to the temperature sensor.

Automatic operation in response to timers

Timer events (time of day and day of week) can be set to:

  • Open the windows
  • Move the window to an intermediate position
  • Close the windows
  • Begin responding automatically to temperatures.

This allows the windows to be set to operate in anticipation of the building occupant’s daily routine. For example, opening before employees arrive to pre-cool the building, or responding to temperatures from when a homeowner goes to bed so that the windows close when the temperature drops in the early hours of the morning.

iPhone timers

Timer events can be enabled or disabled:

  • Remotely from the Powerlouvre App, or
  • Directly on the Apptivate Control Unit.

This allows timer events to easily be disabled as the homeowner leaves the house or enabled as they arrive home.

Note: When responding to timer events both channels of Dual Channel Apptivate Control Units will respond simultaneously.

Control of multiple Apptivate Control Units

Up to 6 Apptivate Control Units can be associated to each Powerlouvre App allowing building occupants to control windows around their home from their Powerlouvre App.

For ease of identification:

  • Each of the Apptivate Control Units can be given a customised name.
  • Each of the channels of a Dual Channel Apptivate Control Unit can be given a customised name.
  • The Powerlouvre App will indicate any Apptivate Control Units which are out of range, or with which a Bluetooth Smart connection cannot be made.

For maximum control and ease of use, all the Apptivate Control Units associated to a Powerlouvre App can be operated simultaneously or independantly.

Control by multiple Powerlouvre Apps

Associations can be established between multiple Powerlouvre Apps and each Apptivate Control Unit, to allow all family members to control the windows from their smartphones.

Note: Only one Powerlouvre App will be able to maintain an active Bluetooth Smart connection with an Apptivate Control Unit at any given time.

For example: Both John and Mary’s Powerlouvre Apps are associated to the Apptivate Control Unit operating the Powerlouvre Windows in their living room. If John opens the windows using his Powerlouvre App, Mary will not be able to close the windows using her Powerlouvre App until John minimises the Powerlouvre App on his smartphone or his smartphone enters ‘sleep’ mode.

Converting from a Breezway Remote Control to an Apptivate Control Unit

Powerlouvre Windows which are remotely controlled can be updated to allow control by the Powerlouvre Apptivate Control Unit but do require some adjustments to the internal and external wiring of the window.

See pdf link below for more information on converting a Breezway Remote Control to an Apptivate Control Unit Technical Bulletin.

Building Management System Compatibility

The Altair Powerlouvre Window System has been reviewed for compatibility by the leading suppliers of building management systems. When considering integration into a building management system, the following should be considered:

  • Breezway does not supply the various sensors which could be used to instigate opening or closing of the windows (eg temperature or rain sensors).
  • Transformer requirements may differ from the requirements of Powerlouvre Windows controlled by Apptivate Control Units.
  • The Powerlouvre Window System does not include an inbuilt electronic mechanism to inform the building management system of its current open or close position.
  • Powerlouvre Motors include limit switches which prevent the motors from continuing to attempt to open or close the window once the window is fully open or fully closed, thereby preventing damage to the motors and electronics.

Apptivate Control Units are not compatible with building management systems.

See pdf link below for more information on Connecting Altair Powerlouvre Windows to C-Bus Systems Technical Bulletin.


Breezway Powerlouvre Windows should be operated at monthly intervals. Frames should be cleaned periodically as per Breezway Care and Maintenance recommendations.

Installation Notes

The Powerlouvre Apptivate Control Unit is incompatible with some switch mode transformers (eg Meanwell GS40 series) due to excessive electrical noise.

Overtightening the installation screws of an Apptivate Control Units can cause the unit to bend which can cause the touch sensor to malfunction.
