On/Off
WhenƔOn/Off button is pressed again,
the system will stop operating and the
Operation lamp will turn off.
When the system is stopped while in the heating*
mode, the fan will continue to operate for
approximately one minute to remove residual
heat from the indoor unit.
Note
To prevent condensation water damage or system failure, do notƔ
shut off the power supply to the indoor unit immediately after
operation. Wait at least five minutes for the condensate pump to
finish draining residual water from the indoor unit.
Characteristics of Heat Mode
The system automatically controls the following operating modes to
prevent the reduction of heating capacity and space comfort.
Defrost operation The system will automatically go into defrost operation to prevent frostƔ
accumulation at the outdoor unit and subsequent loss of heating
capacity.
The indoor unit fan will stop, and “Ɣ
STANDBY
” will be displayed on the
remote controller.
The system will finish the Defrost operation and return to normalƔ
usually within six to eight minutes. It won’t last for more than ten
minutes.
Hot start When the system starts heating operation, the indoor unit fan willƔ
operate with a delay in order to prevent a cold draft.
(In that case, “
STANDBY
” will be displayed on the remote controller.)
