Setting timer number 1 for unit 1-00 to “1” and
timer number 2 to “2” in the individual screen and
then setting timer number 1 to “3” and timer
number 2 to “4” in the batch screen causes the
timer numbers for all units to be set, so timer
number 1 for unit 1-00 will be “3” and timer num-
ber 2 will be “4”.
Example 2
To prevent leaving units on, timer number 1 is
set to “5” in the batch screen.
Setting timer number 1 in zone number 1 to “ ”
in the zone screen after that will change the
timer number for zone number 1, so the setting

∗1: Setting may not be acceptable depending on the
type of indoor unit with which this unit is connected.
∗2: In zone control, the units run in temperature adjust-
ment mode (heating or cooling) for the outdoor sys-
tem for the groups registered to those zones.
Heating or cooling selection is not available.
*3: or or
Changing the ventilation mode cannot be done in

heating. Also, if a Ventiair is connected in the zone,
ventilation and ventilation cleaning operation is pos-
sible. See the included operating manuals for
details.
• When the indoor unit is in heat operation, change the set-
ting to FAN operation through the central remote control-
ler; then, you can switch the fan speed to the extremely
low fan speed. Warm air may blow if any other indoor unit
belonging to the same system is in heat operation.
