This device requires installation inside the indoor unit of your heat pump, involving direct connection to the unit's PCB (printed circuit board). This work must be carried out by a registered electrician or qualified HVAC technician. Incorrect installation can result in serious injury, electric shock, or damage to your heat pump system.
If you choose to proceed with installation yourself, you do so entirely at your own risk. We accept no liability for any injury, damage, or loss arising from self-installation. We strongly recommend engaging a professional for this work.

The App displays the real‑time percentage of heat recovered.
Rather than going to waste, Lossnay's unique Heat Recovery Technology recovers up to 92%* of the heat energy in the outgoing air, which is then used to pre‑warm or pre-cool the incoming fresh air.
In doing so, moisture build‑up in your home is minimised, while healthy humidity levels are maintained and managed in the most energy efficient way possible.
-
The App shows by how many degrees the unique Lossnay Core is able to pre‑warm the incoming fresh air when it crosses over with the outgoing stale air.
Because of the unique Lossnay Core, additional heating of the incoming fresh air in winter is reduced, maximising energy efficiencies.
-
In summer, the App shows by how many degrees the unique Lossnay Core is able to pre-cool the incoming fresh air when it crosses over with the outgoing stale air.
Because of the unique Lossnay Core, if you are using an air conditioner at the same time, the outgoing stale air will be used to pre-cool the incoming fresh air.
As a result, it will take less additional energy to cool to the desired set temperature, maximising energy efficiencies.
-
When Auto Mode is activated, Lossnay’s onboard temperature sensors will automatically enter Auto Bypass Mode when the outside air is cooler than the desired set temperature inside the home.
As a result, cooler fresh air is introduced and stale air is extracted, bypassing the Lossnay Core. This is ideal for cooling down a dwelling that may have overheated during the day, once the outside temperature has dropped in the evening.
^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.
-
A dirty filter or Lossnay Core will force the Lossnay system to work harder, impacting energy efficient operation.
The Lossnay Wi-Fi Control App takes the guesswork out by proactively notifying you when it is time to clean both the filters and the core.

The Lossnay RVS and RVX3 Models have the option of an additional CO2 sensor. When connected with the optional Wi-Fi Control Adapter, CO2 levels can be viewed in real-time making it ideal for schools, medical facilities and offices.
It is well known that poor air quality impacts health, wellbeing and concentration levels. In conjunction with the CO2 sensor, the Lossnay RVS and RVX3 systems intuitively adjust airflow to ensure optimum air quality, no matter how many people are in the room.
The Auto Fan Mode will activate when moderate or high levels of CO2 are detected. Once CO2 levels are back to normal, the system will revert back to the original fan speed.

Seamlessly combine your Mitsubishi Electric Ducted Heat Pump and Lossnay Energy Recovery Ventilation System through your Wi-Fi Control App for ultimate visibility and control.
Because your Ducted Heat Pump needs to be in fan, heating or cooling mode for the connected Lossnay system to operate, you can now choose from two innovative modes to customise your climate control setup.
Use the "Power Interlock" mode, to enjoy set and forget convenience.
In this mode both systems will always automatically activate together no matter which system you initially turn on.Opt for "Fresh Air Fan Interlock" mode to prioritise fresh air circulation; regardless of whether the ducted system is turned on.
In this mode, the Lossnay System will override a ducted system that is turned off and automatically activates the system’s Fan Mode. As a result, fresh air continues to circulate efficiently throughout the home.*Note: To enable Wi-Fi Interlock Control, both units will require a Wi-Fi Interface.
