Powerlouvre App Operation
Compatible devices will have Bluetooth Smart modules installed and have an iOS or Android operating system. Devices include:
- iPhone 4s and newer
- iPad 3 and newer
- iPad Mini and newer
- iPod Touch 5
- Samsung Galaxy Range
- HTC One, MAX
- Sony Experia Range
- Droid RAZR, Ultra, Maxx, Mini
- Google Nexus 4, Nexus 5, Nexus 7 and Nexus 10
- 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 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
- Automatically open the windows to naturally cool the room, or
- Automatically close the windows to retain warmth within the room.
- 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
- 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.
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.
Control of multiple Apptivate Control Units
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
Note: Only one Powerlouvre App will be able to maintain an active Bluetooth Smart connection with an Apptivate Control Unit at any given time.
Powerlouvre Installation Considerations
Electrical Requirements & Installation
- Operating voltage: 24V DC
- Maximum constant current: 0.25A per motor
- Maximum startup current: 0.4A per motor
- Opening time: Approx 14 seconds
- Working temperature: -20 to +60 degrees Celsius
Note: In extreme cold conditions the windows will not operate if there is excessive ice build up or if the louvre blades are frozen together.
Maximum Constant Current Requirements
|Powerlouvre Window Type||Motors per bay||Maximum Constant Current Required||Maximum Instantaneous Start Up Current Required|
|2-9 Blades High||1||0.25 amps per bay||0.4 amps per bay|
|10-18 Blades High||2||0.5 amps per bay||0.8 amps per bay|
The direction in which the Powerlouvre Window moves is determined by the polarity of the low voltage current supplied. Once the Powerlouvre Window has fully opened or fully closed, an electronic circuit stops power being delivered to the motors to prevent the motor being damaged should power be supplied continuously.
Breezway supplies transformers (as an optional extra) that have been specified to meet the requirements of Powerlouvre Windows.
- 240V AC current transformed to 24V DC current.
- 2.0 Amp, capable of providing sufficient instantaneous startup current for up to 6 Powerlouvre motors.
The Powerlouvre Window has no integrated battery back up. If the power supply fails the window cannot be operated. If battery back up is required, systems are readily available and can be integrated by qualified suppliers.
For more information, please read the Battery Backup Technical Bulletin here.
- Cyclical open/closed: 30,000 cycles
- Salt mist: 1,000 hours
- Extreme humidity: 90% humidity at 35 degrees celcius
- Extreme heat: 60 degrees celcius
- Extreme cold: 0 degrees celcius
- Electromagnetic compatibility: Complies with the requirements of EN61000-6-3 and AS/NZS 4251.1
Powerlouvre Opening Configurations
Powerlouvre Windows that are 10-18 blades high contain 2 motors per bay, one motor drives the blades in the top half of the bay and the other motor drives the blades in the bottom half of the bay.
10-18 Blade high Powerlouvre Windows are wired such that the blades in the top halves of all the bays form a bank that opens and closes simultaneously and the blades in the bottom halves of all the bays form a second bank that opens and closes simultaneously.
The top and bottom banks can be operated independantly of each other.
Labelled wires emerge one metre from the top right hand side of the Easyscreen Frame.

Apptivate Control Unit Standard Wiring
Powerlouvre Motors and Apptivate Control Units require 24v DC power. For ease of wiring the Apptivate Control Unit senses the polarity of the current provided from the transformer and automatically adjusts accordingly.
Up to 6 Powerlouvre Motors can be wired in parallel to each Apptivate Control Unit motor group.
Two Powerlouvre Windows, each containing three Powerlouvre Motors are wired in parallel to each Motor Group of the Apptivate Control Unit. With 12 Powerlouvre Motors controlled by the Apptivate Control Unit, a total of 3.0 amps of 24v DC current is required. 3.0 amps of current is supplied by two Breezway 1.5 amp transformers wired together in parallel.
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.

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.
