Description
With this option function, compressor cannot be OFF
during 3min after compressor ON, however, it is
STOP immediately at protection device activated. It
also be STOP immediately at stop by operation SW.
Fan operation time is accumulated and filter sign
turns on in at set time in the remote control.
Once the unit operating mode has been selected,
this function prevents it from being modified from the
remote control.
Once the temperature on the unit has been selected,
this function prevents it from being modified from the
remote control
Fix to use cooling mode only and to prevent heating
mode from being enabled.
Allows, from cooling mode, change automatically to
heating mode (for all units of the same refrigerant
cycle)
Once the fan speed on the unit has been selected,
this function prevents it from being modified from the
remote control
Airflow is kept in setting airflow after unit normal
stoppage during "Delay Time".
The unit runs at maximum fan speed (RCS High
level) under any condition
This function is used to set the value of the offset
in the formula for deciding about Thermo ON/OFF
condition by inlet air temperature for Control by Outlet
Temperature.
This function delays start-up of the air conditioning
system.
The unit runs in high speed during a certain minutes
after switch on the unit. After that time the fan speeds
runs at set fan speed.
