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 influence of other heat sources.
Do not touch the remote controller PC board and PC board parts directly with your hands.
Do not wire the remote controller cable together with or parallel to the connection
cables, and power supply cable of the INDOOR UNIT and OUTDOOR UNIT. It may
cause erroneous operation.
When installing the bus wire near a source of electromagnetic waves, use shielded wire.
Do not set the DIP switches, either on the air conditioner or the remote controller, in any
way other than indicated in this manual that is supplied with the air conditioner. Doing
so may result in improper operation.
7.1. Installing the remote controller
