Remote Controller Setting; Installing The Remote Controller - Fujitsu AR 7 Installation Manual

10. REMOTE CONTROLLER SETTING

.
When detecting the room temperature
using the remote controller, please
set up the remote controller accord-
ing to the following conditions. If the
remote controller is not located prop-
erly, the correct room temperature
will not be detected, and thus abnor-
mal conditions like "not cooling" or
"not heating" 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 where it may be 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.
Do not wire the remote controller cable together with or
parallel to the connection cables, and power supply ca-
ble of the INDOOR UNIT, OUTDOOR UNIT, and BRANCH
BOX. It may cause erroneous operation.
When installing the bus wire near a source of electro-
magnetic waves, use shielded wire.
Do not set the DIP switches, either on the air condi-
tioner 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.
