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.
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:
Commissioning shall only be available through PIN access that will be set up when the MRXBOX-VSC is first switched on. 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. Summer Bypass can be set up via the MRXBOX-VSC. The controller will allow the temperature to be altered to suit the installation requirement. This function is only available on the MRXBOX95AB range. Humidity control shall be adjusted via the VSC from its default position to suit the environment and homeowner lifestyle. This function is only available on the MRXBOX95AB range. Frost protection temperature can be adjusted from the factory default if required using the MRXBOX-VSC. Run-on time can be adjusted from 0-60 minutes via the MRXBOX-VSC.
The MRXBOX-VSC shall allow the homeowner/occupier to carry out the following functions if desired.

The PCB on my MVHR unit (MRXBOX 95-WM2) has 3 sockets that the VSC plug would fit. None have colour coding or a clear reference to the VSC. Where do I plug it in?
Hello Oliver
Hi - I have just purchased a flat equipped with a nuaire mrxbox95ab and find that the flat runs very hot and stuffy. I have experience with mvhr units and understand they’re not a replacement for comfort cooling but am I right in thinking that through this controller I should be able to lower the temperature at which summer bypass is activated? This would mean the system would bring in cooler air and not heat it. Thanks!
