Powerlouver App Operation

The Apptivate Control Unit includes a Bluetooth® SmartTM modules which allows wireless communication between a compatible device running the Powerlouver App and the Apptivate Control Unit.

The Powerlouver app enables:

  • Remote opening and closing of each Apptivate Control Unit. The range of the Bluetooth signal is approximately 10m – 20m. (The range will be maximised by maintaining a clear line of sight between the device running the Powerlouver App and the Apptivate Control Unit.)
  • Naming of Apptivate Control Units, and channels of Apptivate Control Units for easy identification.
  • An indication of the open/close position of the Powerlouver Windows connected to each Apptivate Control Unit.

Compatible devices

Compatible devices will have Bluetooth® SmartTM 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

Security

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

  • Close physical proximity between the Powerlouver App and the Apptivate Control Unit, and
  • An access code (defined by the first Powerlouver 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 maximized 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 Powerlouver App, or
  • Directly on the Apptivate Control Unit.

Powerlouver Apptivate phone1Notes:

  • 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 Powerlouver 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 Powerlouver App allowing building occupants to control windows around their home from their Powerlouver App.

Powerlouver Apptivate phone2For ease of identification:

  • Each of the Apptivate Control Units can be given a customized name.
  • Each of the channels of a Dual Channel Apptivate Control Unit can be given a customized name.
  • The Powerlouver 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 Powerlouver App can be operated simultaneously or independently.

Control by multiple Powerlouver Apps

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

Note: Only one Powerlouver 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 Powerlouver Apps are associated to the Apptivate Control Unit operating the Powerlouver Windows in their living room. If John opens the windows using his Powerlouver App, Mary will not be able to close the windows using her Powerlouver App until John minimizes the Powerlouver App on his smartphone or his smartphone enters ‘sleep’ mode.

Powerlouver Window TypeMotors per bayMaximum Constant Current RequiredMaximum Instantaneous Start Up Current Required
2-9 Blades High10.25 amps per bay0.4 amps per bay
10-18 Blades High20.5 amps per bay0.8 amps per bay
The direction in which the Powerlouver Window moves is determined by the polarity of the low voltage current supplied. Once the Powerlouver 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.

Battery Backup

The Powerlouver 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 following pdf document.

Breezway Transformers

Breezway supplies transformers (as an optional extra) that have been specified to meet
the particular requirements of Powerlouver Windows.

  • 240V AC current transformed to 2.9 amp, 24V DC constant current, suitable for
    powering up to 6 Powerlouver Motors.
  • Able to provide sufficient instantaneous startup current for up to 6 Powerlouver Motors.
  • Built-in overload protection to prevent accidental short circuits from damaging the
    transformer.

It is not recommended that Breezway transformers be junctioned or wired in parallel. If more than 2.9 Amps is required, a larger transformer should be sourced from others.

It is recommended that transformers are located in a position that enables easy power cycling.

Controlling Powerlouver Windows

Control options include:

  • Breezway Powerlouver Apptivate® Control Units, which allow control via a touch sensitive wall plate, remote control via a smartphone application, or automatic operation in response to temperature or timer events.
  • Building management systems, which allow control along with other automated building products and automatic operation in response to various sensors and inputs.

Apptivate Control Unit Standard Wiring

Powerlouver 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 Powerlouver Motors can be wired in parallel to each Apptivate Control Unit motor group.
  • It is recommended that transformers are located in a position that enables easy power cycling.

Building Management System Compatibility

The Altair Powerlouver 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 Powerlouver Windows controlled by Apptivate Control Units.
  • The Powerlouver Window System does not include an inbuilt electronic mechanism to inform the building management system of its current open or close position.
  • Powerlouver 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.
