Description
Auto mode
Using information from the air
conditioner (cooling, heating, fan,
and set temperature) and heat
reclaim ventilation unit (indoor and
outdoor temperatures), this mode
automatically switches between heat
reclaim ventilation mode and bypass
mode.
Heat reclaim ventilation mode
(energy reclaim ventilation)
Outdoor air is supplied to the room
after passing through a heat
exchange element, where heat is
exchanged with the room air.
Bypass mode
The indoor air bypasses the heat
exchange element. This means that
outdoor air is supplied to the room
without heat exchange with the room
air.
