Accurate millimetre-by-millimetre control of the actuators enables an optimal indoor climate during all seasons and all weather conditions. Even a minor change in the window position will have significant influence on the indoor climate – especially on windy days. Data communication between the actuators and the MotorControllers enables the actuators to report back their precise opening/closing position.
This enables the BMS system to know the exact position of the vents at all times, enabling the accurate positioning of the windows from any point. This prevents the BMS system having to continually reset windows to the fully closed position before opening them again to the required new position – so called “hunting”.
MotorLink® technology enables different opening/closing speeds to be used, dependent upon the digital command received. A slow and soundless speed when in automatic mode contrasts with a faster more audible speed when activated by the manual keypads in order to provide an immediate obvious response to the user. There is a third speed of operation for swift opening for fire safety functions.
MotorLink® actuators can be fully synchronised without an external synchronisation module. Up to four actuators can work together on one window with a tolerance of less than 2 mm. Actuators communicate with each other directly and adjust their speed so that they are always fully synchronised, preventing damage to windows caused by the actuators running at different speeds.
An integrated reversing function enables the pressure on the window gaskets to be released by a few millimetres after the windows have been closed. This ensures a prolonged life span of the gaskets and an air-tight seal around the window. The distance which the window actuators reverse can be programmed individually for each window and adjusted after installation if required.
There is no better way to secure a budget than by choosing tried and tested solutions based on international standards. By using MotorLink® products no additional dedicated software development is required – simply set-up some parameters online to interface with KNX, BACnet, LON or Modbus. This reduces commissioning times and associated costs.
