Setting Contents and Setting No.

Items indicated by boldface represent the factory set for the No. of Switch Setting.

Do not make setting of any items not listed in the table above.

 Setting for sequential start function

The central remote controller is equipped with the sequential start function, which starts the indoor units in about 2~3

seconds interval during the unified operation. (The switch is set at "ON" when shipped from factory.)

You can change the sequential start setting from "ON" to "OFF" as follows.

Note:

The sequential start function is for reducing the load of the electrical facility, but not for reducing the load of the large rush

current when the compressors are started at the same time. This is also the same for Unified ON/OFF controller and

Schedule timer.

 Refresh function

This function is used to automatically send "OPERATION MODE" and "TEMPERATURE SETTING" from the central

control system while in operation. In order to disable the refresh function, set the "No. of Switch Setting" to "0".

 Restriction items from sub central remote controller while in double central control function

While in double central control function, no settings of zone interlock and operation code can be made from the sub

central remote controller. In order to disable the refresh function from the sub central remote controller, set the "No. of

Switch Setting" to "0".

 Setting of area designation for forced OFF

• In order to stop all indoor units within the scope of control as a single unit using the entry of T1 and T2, set the "No.

of Switch Setting" to "1".

• In order to stop all indoor units within the scope of control with forced thermostat OFF using the entry of T1 and T2,

set the "No. of Switch Setting" to "2". With this parameter set to "2", no forced stop can be made on any indoor unit.
