Notes:
(1) Hot Dash is started when the operation is started at fan speed ÒAUTOÓ or ÒHIÓ or when the fan speed is changed to ÒAUTOÓ or ÒHIÓ during heating operation, and when the compressor speed
(P item) reaches (WMAX1 or WMAX2) or higher with the room temperature at 8
(2) The maximum compressor speed period during hot dash is finished (1) when the room temperature reaches the heating set temperature (including heating shift) plus S TDSW or (2) when the
thermo is off.
(3) The thermo O
temperature during hot dash is heating set temperature (including heating shift) plus 3
(4) The compressor minimum ON time and minimum O
(5) The time limit for which the maximum compressor speed (WMAX1 or WMAX2) during normal heating (except for hot dash) can be maintained is less than 120 minutes when the room temperature is
18
or more; it is not provided when the room temperature is less than 18
(6) The operation indicator will blink every second during initial cycle operation, preheating, defrosting (including balance time after defrost is finished), or auto fresh defrosting. However, with duct type
models, operation indicator does not blink, but Hot Keep indicator will light. And Hot Keep indicator will also light in ÒThermo O Ó mode.
(7) or preheating judgment, preheating starts if the heat exchange temperature is lower than YNEO and is cancelled if the heat exchange temperature is YNEO plus 0.33
operation using the START / STOP button.
(8) If the room temperature falls to less than 18
in the "Ultra-Lo" mode, the indoor fan stops. When the room temperature is 18
Lo operation during preheating or preheating after defrosting does not stop if the room temperature is less than 18
(9) Compressor speed is determined by instruction sent from indoor unit and corrected by outdoor unit according to such factors as capacity, fan speed, number of units being operated, outdoor
temperature, etc.
(10) If another indoor unit is doing cooling operation, dehumidifying operation or fan operation, heating operation cannot be done.
