Sensible Temperature Control

The sensible temperature control feature allows
comfortable heating which matches the conditions in
the room.
Based on the information collected by the room
temperature thermistor when the heating starts, the
heating capacity is automatically adjusted to achieve
a comfortable heating effect and to reach the
temperature setting quickly.

during operation, check
the air filter for dust. If
dust is present, clean the
filter. See the Care and
Maintenance section. Turn the heater off before
e
cleaning the filter.

The vertical louvers may be adjusted to move the air
flow more to the right or to the left.
Use a screw driver or similar object to bend each
louver to the desired position.
Do not bend repeatedly (no more than 5 times) or else
the louver will break.
The horizontal louver (which determines the vertical air
