Hitachi RAK-25PSEW - Basic Mode

MODEL
Set to "ultra-Lo","Silent","Lo","Med","Hi","ultra-Hi" or "stop" depending on the room
temperature, time and heat exchanger temperature. Set to "stop" if the heat exchanger
temperature is "DNZKOF" during Thermo OFF.(When reach at "DNZKON", fan speed set
to "ultra-Lo" again.)
Set to"ultra-Hi"
Set to "ultra-Lo","Silent","Lo","Med","Hi","ultra-Hi" or "stop" depending on the room
temperature, time and heat exchanger temperature. Set to "stop" if the heat exchanger
temperature is "DNZKOF" during Thermo OFF.(When reach at "DNZKON", fan speed set

Set to "ultra-Lo","Silent","Lo","Med","Hi","ultra-Hi" or "stop" depending on the room
temperature, time and heat exchanger temperature. Set to "stop" if the heat exchanger
temperature is "DNZKOF" during Thermo OFF.(When reach at "DNZKON", fan speed set
to "ultra-Lo" again.) The fan speed is controlled by the heat exchanger temperature; the
overload control is executed as in the following diagram:

“ultra-Lo”
Operates at “Lo” regardless of the room temperature.
Runs at “ultra-Lo” when thermo is off.
Operates at “Silent” regardless of the room temperature.
Runs at “ultra-Lo” when thermo is off.
Operates at “Med” regardless of the room temperature.
Runs at “ultra-Lo” when thermo is off.
1. Runs at “Hi” until room temperature reaches to
“setting temperature-SFTDSC” after operation is
started.
2. Runs at “ultra-Lo” when thermo is off.
