Air flow rate changeover button
Use this button to change the air flow to " " Low, "
" High, "
FRESH UP" Low Fresh-up, or "
FRESH UP" High Fresh-up
mode.
When this indication does NOT show, the volume of outdoor air
supplied into the room and that of the room air exhausted
outdoors is equal.
For "FRESH UP" operation
▪ If the Fresh-up setting is set to "Fresh up air supply": The
volume of outdoor air supplied into the room is larger than that
of room air exhausted outdoors. This prevents odours and
moisture from kitchens and toilets from flowing into the room.
This is the factory setting.
▪ If the Fresh-up setting is set to "Fresh up air exhaust": The
volume of room air exhausted outdoors is larger than that of
outdoor air supplied into the room. This prevents hospital
odours and airborne micro-organisms from flowing out of the
room into the corridors.
To change this setting, see List of settings in the installer and
user reference guide.
