7. REMOTE CONTROLLER SETTING
CAUTION
When detecting the room temperature using the remote con-
troller, please set up the remote controller according to the
following conditions. If the remote controller is not located prop-
erly, the correct room temperature will not be detected, and
thus abnormal conditions like “not cooled” or “not heated” will
occur even if the air-conditioner is running normally.
• Locate where an average temperature for the room being
air conditioned will be sensed.
• Do not locate directly exposed to the outlet air from the
air-conditioner.
• Locate out of direct sunlight.
• Locate away from the infl uence of other heat sources.
Do not touch the remote controller PC board and PC board parts directly with your hands
.
