a. Start
Hot start control commences when defrosting is completed.
b. Operation
“PREHEAT” appears on the remote control display. (Other displays remain unchanged)
The indoor unit fan stops. In addition, during hot starting, the louvre stays at the horizontal position (angle 0°C).
c. Cancelling
Hot starting will be cancelled when the temperature detected by the indoor unit pipe temperature sensor is 18°C or higher,
or after a maximum 1 minute has passed since defrosting was completed.
After cancellation, the “PREHEAT” display on the remote control disappears and the louvre operation returns to the previous
setting.
(However, the indoor unit fan operates at LOW speed for 2 minutes after cancellation, and then returns to the previous
setting.)
