Application

Suitable for all building types, regardless of need and size.

Description

The NV Embedded® controls solution uses intelligent control logic hosted on the control panels (also referred to as MotorControllers), which is configured to the specific building layouts and zone requirements. This software automatically controls the windows and indoor climate in each zone, according to desired setpoints and readings from the internal room sensors and external weather station. The system selects the window positions for a room according to sensor readings including temperature and CO2, taking into account wind, rain, and outdoor temperature readings from the weather station. 


Features and benefits:

  • Cloud based solution.
  • Controls natural and mixed mode ventilation as well as heating, sun screening and cooling.
  • Offers individual control and visualization of the indoor climate via app (Android and IOS).
  • Natural ventilation: suitable for comfort ventilation to ensure that the building’s users enjoy a comfortable indoor climate.
  • Mobile management: app to create a better indoor climate by opening and closing the motorised windows.
  • Cloud based: the system is accessible through a cloud-based setup, which enables remote monitoring and service.
  • Heating/ cooling control: heating and cooling are closely linked to the natural ventilation control, which ensures that the NV Embedded® system can minimize, for example, heat energy loss in the winter while it uses automated natural ventilation to create a quality indoor climate.
  • Data logging: NV Embedded® provides continuous logging and storage of all data concerning interior climate, weather conditions, window positions, etc. The data can then be analysed at any time, playing an active role in adjustments to the system and troubleshooting.
  • Solar screening: effective control of the sun screening is an important contributor to maintaining a comfortable indoor climate as the screens can be used as both a shield against extreme overheating and as additional insulation in the winter.
  • Night cooling: openings allow the cooler night time air to enter the building while removing heat and energy from the internal fabric of the building. This cooling allows the structure to re-absorb some of the internal heat gains the following day.
  • Accurate surveillance of the indoor climate: NV Embedded® constantly monitors both the indoor climate and the outside weather conditions, thereby adjusting the amount of ventilation and keeping the indoor climate at a comfortable level.
