The new standard in demand-controlled ventilation 

Is your ambition to equip every single-family home you tackle with a solid, affordable, user-friendly and energy-efficient central VST3 ventilation system? Then Renson's OxyGreen Light is the most appropriate unit for that, in combination with the supply of fresh air via window vents. Especially if you know that the central ventilation unit is now equipped as standard with a built-in humidity sensor for the removal of contaminated air from wet areas in the house. 

Modular expansion

Thanks to additional external CO2 and humidity sensors (which also have a control knob to choose between demand-controlled ventilation, night mode or boost), the OxyGreen Light can (also afterwards) be expanded easily, modularly and tailored to everyone's needs into a complete demand-controlled ventilation system that keeps the indoor air quality in the entire house up to standard and allows the customer to make additional energy savings. Those extra sensors communicate wirelessly with the ventilation unit. This way, the unit will only start ventilating more as soon as the indoor air quality in the house is poor, regardless of the room where this is measured by the sensors. Once the indoor air quality is back up to standard, the ventilation system automatically switches back to the basic ventilation level. So residents do not have to worry about this. Everything is fully automatically controlled for them by this intelligent and demand-controlled exhaust fan, although via the optional (intuitive) sensors/manual controls or four-position switch it is also possible to manually select boosting ('max') or a night mode ('moon' icon) instead of demand-controlled ventilation ('comfort').

Easy and compact to install

The quick and easy assembly of this robust ventilation system and the simple connection of additional sensors guarantee you as installer a smooth and correctly functioning installation. The fact that the ventilation unit is the most compact of its kind on the market is an additional advantage when renovating, but also makes it universally applicable for wall, ceiling or floor mounting.
