Lunos Operation Manual
Knowing how to operate the Lunos e2 and eGO HRV systems will help you get the most out of
balanced, decentralized heat recovery ventilation. Your Lunos should already have been set up to be
operating continuously and providing healthy indoor air quality to your living spaces. However, you
may want to change the flow rates at night or in summer depending on your individual preferences.
This guide will help you determine the best ventilation strategy for your needs.
How Lunos works – an introduction
The basic Lunos unit is a through wall fan, with a ceramic regenerative heat exchanger behind it. But
the fan doesn't become a heat recovery ventilation
system
until two fan units are combined in pairs.
Each Lunos system provides heat recovery ventilation by synchronizing the direction and speed of air
flow through the ceramic cores. By reversing the air flow on regular intervals, the
ceramic cores capture and release heat to condition the interior space at optimal efficiency - while
maintaining balanced ventilation. Depending on your Lunos model, the reversal interval will be either
55 or 70 seconds.
With the Lunos e², fan pairs will be inside two different tubes that are generally on opposite ends of
your space. (For the Lunos eGO, both fans are in the same tube.) A maximum of 4 Lunos e2 fans can
be connected to one controller (a double rocker switch or rotary dial switch aka “Miceli”). Therefore, if
your dwelling unit has more than 4 fans, you will have more than one controller.
