VL-250CZPVU-R/L-E Mechanical Ventilation Heat Recovery Unit

Built-in full bypass function
This function allows the unit to bring in fresh air from outside without recovering the heat. This can be ideal for cooling down a dwelling that’s overheated during the day when the outside
temperature has dropped in the evening. Using temperature sensors, the unit can automatically enter bypass mode when it detects the space is hotter than desired and the outside air is cool enough.

Third Filter Slot
A third filter slot can incorporate an optional NOx filter on the supply air side to
clean the air even in the most polluted environments. Having the filter built into
the unit itself provides easy access for regular maintenance.

Built-in LCD Controller
The LCD controller allows easy control and commissioning of the unit with a clear
display showing normal, boost, and purge modes. Up to 4 speed settings can be
commissioned digitally in percentage increments to ensure constant and accurate settings.
