1.10 Refreshed Operation
Refreshed operation is the function to transmit setting of "Temperature control", "Temperature setting" automatically
from DCS302CA61.
"Refreshed operation" is "ON" when shipped from the factory.
Factory Setting
It depends on the setting of outdoor systems that an indoor unit setting is "Temperature control" or "Temperature setting"
„
In case of Refreshed operation is "ON"
• When setting is changed by DCS302CA61, it operates by this setting from the next operation.
If it sets up with 26 °C in cooling by DCS302CA61, "in the case of the equipment which has not carried out zone
setting by a central remote controller, it operates from next with the mode of operation and preset temperature which
were set up on the individual screen."
In the case of the equipment which carried out zone setting, it operates from next with the mode of operation and
preset temperature which were set up on the zone screen.
(Priority is given over the mode of operation and preset temperature which were set up on the zone setting screen).
When it sets up all at once, it operates from next with the mode of operation and preset temperature which were set
up last time on the individual screen (Equipment which has not carried out zone registration), or the zone screen.
If a setting change is made with 26 °C of cooling by a central remote controller on an individual screen (Equipment
which has not carried out zone setting)" next operation will also be operated at 26 °C in cooling. (Even if it has
changed into heating operation, fan only operation with wired or wireless remote control, it operates at 26 °C in
cooling.)
• When zone registration is carried out by Central Remote Controller.
It operates from next time with the value set up in the zone.
When a zone 1 is set up with 20 °C of heating. (Refer to the system of the following figure.)
When controlled by Central Remote Controller, 3 indoor units registered into the zone 1 are operated by 20 °C of
heating. Because priority is given to zone setting, even if it sets up 2-02 with 25 °C of heating on an individual screen
from Central Remote Controller, 2-02 is operated at 20 °C.
• When there are two or more indoor units in a zone.
Because an operating mode depends on the outdoor unit, the operating mode of each indoor unit does not become
the same setting.
When the outdoor unit system 1 is cooling, the outdoor unit system 2 is heating and it operates by the system of the
following figure. Setting of a zone 2 is operated in heating mode, because 2-03, 2-04, and 2-05 do not have a
cooling/heating selection right as for 26 °C of cooling, but temperature setting becomes 26 °C.
When you unify the operating mode of an indoor unit in the same zone, please set up a zone in the indoor unit of the
same outdoor unit system.
