- 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 so that the unit bypasses the heat recovery function in warmer months. Vireo's summer by pass is TRUE.
When the by-pass is activated it continues to provide supply air to the dwelling, maintaing a balanced ventilation system for the home. It doesnt just slow down or shut down the supply air.
It isn’t filter by-pass either (unlike many other units on the market).
Greenwood SummerSMART technology really is SMART and has been designed to maximise comfort at all time and ensure Indoor Air Quality is maintained.
- Innovative Condensate Connection: 70%* quicker install time can easily be achieved on-site
As a result of working directly with installers, we have developed revolutionary technology DISO (Dual Inlet Single Outlet) which enables Vireo to the be the only true universal product on the market.
DISO allows condensate to be collected on either side of the unit without issue. 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.
