Previous turbo fan

In the case of a
conventional fan, the air
outlet range was narrow
as the air ow moved to
the motor side which
meant the velocit y of air
passing through the heat
exchanger was uneven.

2-stage turbo fan

A evenly spread air distribution across
the heat exchanger is possible due
to the new 2 stage turbo fan which
produces two separate airow

The room temperature can be set to go no lower than 50°F (10°C),
thus ensuring that the room does not get too cold when not occupied.

Caution)

When the room temperature is higher than 50°F (10°C), “ • MIN. HEAT” operation will not start. Operation starts and maintains the room
temperature at 50°F (10°C) when the temperature drops below 50°F (10°C).

When “ • MIN. HEAT” operation stops, the room set temperature quickly returns to the preset temperature.
