Defrost Operation
• The system will automatically go into defrost operation to
prevent frost accumulation at the outdoor unit and loss of
heating capacity.
• The indoor unit fan will stop, and "STANDBY" (Defrost/Hot
Start) will be displayed on the remote controller.
• The system will return to normal operation usually within six
to eight minutes (but not more than 10 minutes).
Hot Start
• When the system goes into heat mode, the indoor unit fan
will stop in order to prevent a cold draft. (In that case,
"STANDBY" (Defrost/Hot Start) will be displayed on the
remote controller).
DRY MODE
Preparation
• For equipment protection purposes, apply power to the
outdoor units at least six hours before"starting the operation
of the system.
• The dry mode may not be selected if the remote controller is
master controlled and the system is not already in the cooling
mode of operation.
Operation
1. Press Mode Button several times until the Dry mode is
selected. (The Dry mode may not be available depending
on the type of indoor unit.)
2. Press On/Off Button. The Operation Lamp (green) will
illuminate and the system will start operating. In Dry Mode,
the system maintains automatic temperature and fan speed
control. Therefore, temperature setpoint or fan speed
settings are not available while the indoor unit is in the Dry
Mode.
