After thermo.-on, until the set fan speed is reached, cool air is output (emanates) from this begin-
ning heating operation and the indoor fan speed is controlled as shown below to prevent cold draft.
¶ When the fan speed is LL or off, “STAND BY” is displayed at the remote controller.
• Room temperature thermostat off
• Condensation elimination operation
• After heating operation start, until the indoor coil E2 temperature is 27 ˚C or higher (6 minutes max.)
¶ After heating operation start, the fan speed approaches the set fan speed as the indoor coil E2 temperature
rises.
(2) Fan speed control after set fan speed is reached
¶ Indoor coil E2 temperature ] 43 ˚C, the control below is performed.
¶ Indoor coil E2 temperature [ 38 ˚C, until indoor coil E2 temperature ] 43 ˚C, the fan speed accelerates in a
rising slope.
¶ When the fan speed changes, it does not change again for 1 minute.
