2.4.4 Description of Functions
Individual Screen, all Screen, Zone Screen
This controller can perform operations in the individual screen, all screen, or zone screen.

Individual screen
The individual screen is used when performing group operations.

All screen
The all screen is used when performing operations for all units at once.

Zone screen
The zone screen is used when performing zone operations.
Basic Functions
Zone Control Functions
Cool/Heat Changeover and Eligibility Setting
Note:
Refer to the next page for the selection of cool/heat mode (eligibility for cool/heat changeover).
Descriptions of outline
Individual/Zone control Up to 64 groups (Max. 128 units and max. 16 units per group) of indoor units and HRV units can be controlled by
individually or by zone.
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.
Descriptions of outline
Possible control The operation mode of the outdoor unit can be changed by the local remote controller or by the central remote controller.
(For test operation, change setting of cool/heat selector switch of the outdoor unit.)
Remote controller acceptance/rejection You can set the remote controller acceptance/rejection on the central remote controller by the local remote controller.
"NOT AVAILABLE" DISPLAY
(NO FUNCTION DISPLAY) If a function is not available in the indoor unit even if the button is pressed, "NOT AVAILABLE" is may be displayed for a
few seconds.
