    Greenwood CommissionSMART™

    In just 8 simple steps, Vireo can be set up and commissioned – all via an ‘ style’ controller located at the front of the unit. This simple and easy process contributes to GIP being achieved whilst keeping installers happy with fuss-free onsite requirements.

    True Summer By-Pass: Unlike others, it provides 365 days of Fresh Filtered Air

    Greenwood SummerSMART technology has been designed to reduce issues with overheating in the summer in a true and effective way – unlike many other units available in the market.  

    When the by-pass is activated, the Heat Recovery System remains TRUE.  In other words, it continues to provide balanced ventilation to the entire house by by-passing the heat exchanger and NOT slowing down or shutting off the supply air.  

    In addition, it still filters the supply air during the by-pass mode.  Many other units on the market operate a summer/filter by-pass mode which further affects Indoor Air Quality, especially in homes where allergies and asthma are present.  
    Greenwood SummerSMART is completely innovative and unique and has been designed to maximise comfort at all times as well as ensure Indoor Air Quality is maintained. 


    70%* quicker install time can easily be achieved with innovative condensate technology
    As a result of working directly with installers, we have developed revolutionary technology – DISO (Dual Inlet Single Outlet).

    DISO allows condensate to be collected on either side of the unit without issue which enables Vireo to be the only true universal product on the market.. The unit can simply be handed (Right or Left) at the touch of a button after installation through the set-up wizard. This removes the need to hand the unit on-site which usually involves a lengthy disassemble of the product, adding more risk to the overall installation – this can take up to 20 mins!


    Greenwood HumidiSMART™

    Vireo’ boost ventilation rates can be controlled by humidity levels in the property. Greenwood HumidiSMART is a patented technology that uses man-made spikes to boost ventilation, rather than waiting for a generic point to be reached.


    Greenwood GIP Product
    Guaranteed Installed Performance (GIP) is a fundamental part of Building Regulation compliance and focuses on signing off the installation for the first time. 

    A Greenwood GIP Product provides;

    – 100% airflow adjustability
    –  Low energy motor technology for the most efficient performance
    – SMART Technology to make installation and commissioning easy as well as continued GIP in the home for the occupant
       – Independent CE Testing
