The design of the automated Altair Powerlouvre Window was based, in one aspect, on the humble light bulb.

A light bulb can be turned on and off by wiring it to a simple switch on a wall. A light bulb can be integrated into a system that turns the light bulb on when motion is sensed. The same light bulb can be integrated into a system that turns the light bulb on when the homeowner arrives home, off when they go to bed, makes it flash in time to music and makes it turn on when motion is sensed, but only if the homeowner is not home at the time… or any other scenario that you can imagine!

A light bulb can be used in all these different ways because it is designed to simply turn on when power is supplied to it and turn off when no power is supplied to it.

Similarly, an Altair Powerlouvre Window is designed to open when 24V of DC power is supplied in one polarity, and to close when power is supplied in the opposite polarity. Provided this basic principle is followed, Altair Powerlouvre Windows can be controlled by wiring them to simple ‘open’ and ‘close’ switches, or can be integrated into more complicated switching systems that operate the Powerlouvre Windows in response to sensors, timers and switches.

To help electricians, builders and specifiers, Breezway has published the “Powerlouvre Electrician’s Guide” which contains all the key information, instructions and diagrams needed to:

  • Specify power sources
  • Understand switching and control requirements
  • Control Powerlouvre Windows using Powerlouvre Apptivate Control Units
  • Integrate Powerlouvre Windows into building management systems
  • Control Powerlouvre Windows using DIY automation systems
  • Control Powerlouvre Windows using bell press switches
  • Consider wiring requirements on the building site

The Powerlouvre Electrician’s Guide is available as a pdf document from the Breezway website and can easily be included in specification and tender documentation so that builders can more accurately quote on jobs including automated Powerlouvre Windows. To learn more please visit
