9-9-9. Manual Adjustment Function of Outside Temperature (TO) Sensor
This function is provided to fix TO sensor value manually by the switch operation on the interface P.C. board in
the outdoor unit. When the unit stops abnormally due to TO sensor failure, etc, an emergent operation is
available by setting up the value manually to position near the current outside temperature.
[Operation]
(1) Set the rotary switches on the interface P.C. board to numbers as follows:
• SW01/SW02/SW03 to [2/1/15]
• 7-segment display: [ t o ]
(2) Keep pressing the push-switch SW04 on the interface P.C. board for 1 second or more. The mode changes
to the TO sensor value fix manual mode.
(3) Pressing the push-switch SW04 increases the setting temperature and pressing the SW05 decreases the
setting temperature. Set the temperature to any values.
[Clear]
Return SW01/SW02/SW03 on the interface P.C. board in the outdoor unit to [1/1/1].
NOTE) If operated with TO sensor fixed by this function, the system control operation of the air conditioner may
not be based on the specification of the product. Therefore an emergent operation should be restricted
to a day or so.
When the outside temperature is 45ºC or more, set to 45ºC (SW02="9")
