Setting conditions Description
This function is used to adjust
the temperature difference
between the temperature read
by the inlet sensor and the real
room temperature.
This is useful when the inlet air
thermistor is not placed inside
the indoor unit or due to uneven
heat load.
Note:
• The "02", "03", "04" settings
may not be available
depending on the type of
indoor unit.
• This setting shall be
performed separately for
each indoor unit, even in
case that multiple indoor
units are connected to one
remote controller.
This function keeps the fan
running during the Thermo-OFF
sequence, at the fan speed set
on the remote control switch, to
prevent the stratification of air in
the room.
Use at 00 conditions
This function is used to modify
the period of operation after
which the air filter cleaning
indication is shown in the remote
control.
For RPK-FSR(H)M models,
the factory setting is b4=00:
Standard setting 200 hours.
This function prevents the
modification of the operation
mode of the unit from the remote
controller and from central
controls, once it has been
selected.
This function prevents the
modification of the setting
temperature of the unit from
the remote controller and from
central controls, once it has
been selected.
This function is used to limit the
operation mode to cooling only
and to prevent heating mode
from being enabled.
This function enables the
selection of Auto cool/heat
operation mode. If the function
is not activated, Auto cool/heat
mode cannot be selected on the
remote control switch.
