PassivHaus certified, the LG features a heat recovery system with a counter-current heat exchanger with up to 90% efficiency that is  made of recyclable plastic. It also has an automatic 100% summer bypass as standard, so heat won't be recovered on those hot-summer nights.

With the energy-saving Belimo fans driven by the latest EC (electronically comutated) motor technology, you can rest assurred that there will be minimal electricity consumption. As standard we also specify high grade fresh air intake F7 filters which prevent dust, pollen and allergens from entering the home, useful for Asthma and allergy sufferers. The LG range can be either floor or wall-mounted.

Once commissioned, the LG heat recovery ventilation system can be left to run by itself, as various sensors within the infrastructure, feedback data to the control board. This in turn will adjust the system's operating parameters to target a healthy and desirable home environment. However, in most situations you may still want at least some level of control to vary what those targets are. The operation of the LG system is simple either via the MINI or touch-screen controller.

MINI controller operating mode: Summer, Winter or automatic ventilation level 1-3 filter clean/replacement indicator fault message LAN connection for remote diagnostics and App touch-screen controller operating mode: Summer, Winter or automatic ventilation level filter clean/replacement indication 24/7 programming demand driven CO2 and humidity control (optional) target temperature control including optional post-duct heater information on measured values LAN connection for remote diagnostics and App Of course what system would be without it's free smartphone app; for Android and iOS, it can easily operate your LG whether you're at home or out and about and it is useful for remote diagnostics.
