Nuaire Mrxbox Vsc Touch Screen Controller

NUAIRE MRXBOX TOUCH SCREEN VSC (Visual System Controller)

The stylish touch screen wired controller has been designed to make controlling your MVHR ventilation system simple, for both the installer and the end-user. With a 3.5” touch screen display, the unit can be surface or semi-recess mounted and is compatible with a standard 2 gang recess backbox. When installing the MVHR, you can commission the unit through the controller and program settings such as airflow, frost protection and summer bypass. For the end-user, they will be able to tailor the unit to suit their lifestyle, through setting a timed or rising boost or even putting the unit into holiday or night mode to save on energy.

Specification:

The MRXBOX-VSC is compatible with the majority of Nuaire MRXBOX95 heat recovery units (Models WM2, WH1, LP1).

The controller comes complete with commissioning and end-user functions. The display will be a 3.5 inch LCD display and will remain on standby until such time the screen is touched. The initial display will show the MVHR system status as listed below:

Fan Speeds for both the supply and extract fan are set independently and are infinitely variable, the display will show the percentage of speed the fan is running at and will allow each fan to have 3 separate saved speed set points to allow the MVHR unit to run at background rate, boost rate and a further purge flow rate.
