<Action when indoor unit's power is OFF>
[Indoor unit's power is OFF with outdoor unit's power ON]
As long as the outdoor unit's power is not turned OFF, the refrigerator will continue to work even when turning the air-
conditioner's power ON/OFF, and the air-conditioner will stop.
[When the outdoor power has been reset]
[Regarding transmission establishment]
Description:
In the following instances, the outdoor unit establishes the quantity of indoor units and memorises it.
• When inputting power at installation
• When pushing the RESET button (hold for 5 seconds)
[Verifying transmission when restoring outdoor unit's power]
• If the outdoor unit's power has been reset and the power is ON, the pre-memorised indoor unit connection conditions
will be verified.
• At this time, if the connected indoor unit quantity does not correspond, it will remain in the initialise state, and the
outdoor unit will stop the refrigerator and air-conditioner.
• With the operation switch turned OFF, holding the RESET button will result in recognition of indoor unit and boosters
with power ON, and will allow operation in emergencies. However, if the indoor unit's power is OFF, there is a chance
of the expansion valve being open, which can lead to damage of the compressor, so please take care.
Also, when there is not a single transmitting instrument (indoor air-conditioner, booster) connected, set the DS2-1 to
ON.
