Natural ventilation control

02 Apr Natural ventilation control

Natural Ventilation ControlWindowMaster has launched its MotorLink automated window solution into the UK market, providing a safe window control option for the facade and building controls industries.

The operation of buildings accounts for 40% of all energy consumption in Europe, and automated natural ventilation or hybrid systems with mechanical and natural ventilation can help reduce the carbon footprint of a building.

MotorLink is a state-of-the-art digital data communication technology that provides improved control and functionality where automated windows and natural ventilation are part of a building management system (BMS).

Because it operates within open standards, its operation does not require expensive, dedicated software systems. Furthermore, its functionality means that BMS suppliers and facade companies can deliver robust, flexible control solutions tailored to specific project requirements.

MotorLink features precise position control, three-speed actuator operation, synchronisation between multiple actuators on the same window, and reduced risk of entrapment. Other features include a reversing function that protects the weather seals around the window, fault indication and online set-up.

Millimetre-by-millimetre control enables an optimal indoor climate to be obtained whatever the weather. Two-way communication between the window actuators and the MotorController enables the BMS to accurately position the windows. The position is then logged in a secure memory within the electronics of each MotorLink-enabled actuator, retaining the information even in the event of power loss.

Full synchronisation means that up to four actuators on one window can work together within a tolerance of less than 2mm. The system enables the actuators to communicate with one another so that they are always working at the same speed to avoid damage to the window.

Reversing and pressure safety functions within the system reduce pressure on the window gaskets, prolonging the lifespan of the seals and the airtightness of the windows. In addition, actuators equipped with MotorLink technology can be programmed to stop and reverse if an object is encountered when the window is closing.

Richard Arnott, UK and Ireland market manager for WindowMaster, said: “WindowMaster has used its years of experience to make the programming and operation of automated natural ventilation and smoke ventilation systems as easy as possible. The new MotorLink range of MotorControllers is very versatile and interfaces with building management systems using open bus communication standards including KNX, LON, Bacnet and Modbus.”
