Supply air Return air Outdoor air Exhaust air CO2 Sensor The Sensible Heat Lossnay LGH-RVS Series, allows diverse solutions and options in response to customer needs. Three key features, namely “Easy Installation”, “Low Noise Operation”, and “High Energy Ef ciency”, provide energy savings and comfort! Automatic operation with CO2 sensor and PZ-62DR-E Fan speed automatically changes depending on CO2 concentration. A CO2 sensor connected directly to a Lossnay RVS unit optimizes the fan speed according to the level of CO2 detected. It improves total heat exchange efficiency and contributes to energy saving. CO2 levels are indicated by LED lights.

Three key features, namely “Easy Installation”, “Low Noise Operation”, and “High Energy Efficiency”, provide energy savings and comfort! Make Heat Recovery Ventilation Visible – with Optional Lossnay Wi-Fi Control Elevating air quality and maximising energy efficiencies has never been easier, because now the power is in your hands. See by how many degrees Lossnay is pre-warming or cooling your room in real time, helping you save on your power bill because less additional heating is required to get a room up to temperature. And in summer monitor by how many degrees Lossnay reduces your room temperature, using Automatic Free Cooling* Mode. View actual CO2 Levels and watch how the system automatically activates Boost Mode to maintain optimum air quality. The App will also proactively remind you when it is time to clean your filters to maximise both cost efficient operation and health benefits. Lossnay Wi-Fi Control truly is the smart evolution in fresh air ventilation. *In comparison to using a dedicated cooling device. The unit will continue to use a small amount of power to bring colder fresh air from outside.
