Unified ON/OFF ON/OFF can be set for each zone, and can be controlled simultaneously for entire system by push button or by contact
signal from outside.
Malfunction code display The status of each group is always displayed, such as ON/OFF, error, etc. If the error occurs, it displays the contents of
error by malfunction code through the self-diagnosis function.
Connection of unification adaptor for computerized
control
By connecting the unification adaptor for computerized control (option), it can be linked with the central monitoring panel
and etc. by contact signal, which enables you to operate ON/OFF simultaneously or monitor the operating status.
Remote control acceptance/rejection It is possible to restrict the function of local remote controller.
(Only ON operation rejection, or ON/OFF operation rejection)
2 central controllers By connecting two central remote controllers, the same air-conditioner can be controlled from 2 locations (By tenant or
administration office.)
Descriptions of outline
Zone control The zone function is a function to control one or more group of air-conditioner, and the operation setting such as ON/OFF
etc. can be made by zone.
Up to 64 zones Up to 64 zones (64 groups for each zone) can be set. However, the group setting spreading over the plural zone cannot
be set.
Zone register When the power is supplied first time, each group is registered in each respective zone. If you can simply register the
several groups in the same zone by switch, so that you can have simultaneous operation of the units in that zone
immediately. (The operation of temperature setting and etc. is also controlled by zone simultaneously.)
Zone setting By adding the zone setting function (Zone “0”) from the central remote controller, you can set the same setting for all the
zone registered by single operation.
ON/OFF control of zone For example, if there are three groups in one room and if you register these three groups as one zone, you can operate
these three groups simultaneously by single operation (ON/OFF, temperature setting etc.).
You still can operate each group individually by local remote controller.
Maintaining zone setting Even if the power is turned off, the zone configurations set are maintained semi-permanently. (saved in non-volatile memory)
Cool/Heat changeover by zone The cool/heat changeover can be made by zone. However, it is required to have a master group for Cool/Heat changeover
in that zone.
Batch operation The same setup is possible at one operation to all the groups registered on the "All" screen.
No local remote controller Even if there is no local remote controller, you can still perform the same operation. There is no problem even if no remote
controller is connected. (However, in this case, each one air-conditioner consists of one group.)
Combination with other controllers You can also combine with a unified ON/OFF controller and a schedule timer.
(Refer to the system configuration for details.)
Connection to central monitoring panel You can also combine with an Interface for use in BAC net
and a data station in order to connect to the central monitoring
panel. A parallel interface can also be connected.

Cool/heat Selection Eligibility Setting by Remote Controller for Indoor Unit
The outdoor unit of can freely be selected the operation mode (fan, dry, auto [Heat Recovery only], cooling or heating) by
the remote controller for indoor unit. However, you have to set the selection eligibility for fan, dry, cooling and heating
operation on the one of the remote controller out of the indoor units connected to the outdoor unit. For Heat Recovery
series and the function unit (for heat recovery), if 2 or more indoor units are connected to one Branch Selector unit, you
have set the selection eligibility for fan, dry, auto, cooling and heating operation on the one of the remote controller out of
the indoor units connected to the Branch Selector unit.
(Only the remote controller having the selection eligibility can change the operation mode.)

It is also possible to set the selection eligibility on the wireless remote controller.
It is not possible to set to "Dry" with the Central Remote Controller.
Control with Two Central Remote Controllers
The central remote control equipment is newly designed to "B" type, which has been added with a new control function
for 2 central remote controllers. However, be sure that the relation between Main/Sub of the central remote controller is
different from those of local remote controllers.
Note:
Understand that if the timer No. is registered by the sub-central remote controller, it will be overidden by the Main remote
controller setting upon operation. [Timer mode acceptance for local remote controller (mode no. 8,9,18, and 19)]
<Explanation of the above figure>
If you operate the central remote controller in the sequence of N and O, the indoor unit is set for cooling / temperature
setting 75°F.
However, the display of zone setting of the master remote controller remains at heating / temperature setting at 80°F.
<Cautions>
Operation code cannot be set by the sub central remote controller.
Combined zone operation can only be set by zone registration of the main central remote controller.
Both main and sub central remote controller are operated by a last priority command for the functions other than the
above.
However, the display on the central remote controller cannot be changed by each other. (On the display for the group,
you can monitor the present operation status.)
