Schedule Timer Address Settings (5, 6, 7)
A maximum of 8 schedule timer units can be connected to the inter-unit
control wiring. If multiple units are connected, use the setting switches
and allocate the addresses, taking care to avoid duplication.

When multiple schedule timers are installed, set this switch to ON to
perform time settings for multiple units simultaneously. One minute
after the time is set, the time at the other schedule timers will change
to match the set time. (Ordinarily this switch is OFF.)
Spare (6, 7, 8)
Be sure that these switches are OFF when the system is used.
Creating Timer Groups
The schedule timer can be set for 6 time status changes. These can be
used to create up to 8 groups (timer groups). For systems in which sched-
ule timers are used, set the timer groups to match the central control
addresses of the indoor units that will be subject to group timer control.
The timer-group settings for the schedule timer involve assignment of
central control addresses. Therefore, use the system controller (or other
central control device) or wired remote controllers to set the central con-
trol addresses of the indoor units, then make the schedule timer settings.

Procedure for making fixed timer group settings (fixed groups)
(1) First, use a different central control device (system controller or other
device) or the wired remote controllers to set the central control
addresses, as assigned in the figure above, to the indoor units that will
be subject to group timer control.
(2) Next, use S41 switches 2 and 3 to set the number of timer groups you
wish to create.
(3) Finally, turn ON the schedule timer power. Initial communications are

performed. (SCAn blinks in the display.) The normal display appears
OFF
after several minutes, and the timer group settings are confirmed.

manually assigned timer group settings are confirmed.
Memory Backup Switch
After installation is completed, check that the backup switch on the
reverse side of the schedule timer PCB is turned to ON.
(The backup battery will retain the current time for up to 100 hours.)

Checking the Central Control Addresses and Operating
the Units that are Controlled by the Schedule Timer
The schedule timer communicates with the indoor units to check which
central control addresses can be controlled with the current timer control.
The schedule timer can then be used to start and stop these units.
(1) Press and hold the schedule timer
32
and CLEAR button for 4 seconds or longer. "Ad-(central control
address)" appears in sequence, blinking.
(2) Use the GROUP button in the
control addresses in sequential order. In this way, it is possible to
check which central control addresses in the displayed timer group can
be operated by the timer.
(3) With the selected timer group displayed, press the timer
ton. Each time the button is pressed the indoor units in the displayed
48
timer group start or stop. Pressing the
permits all items (operation start/stop, operation mode, temperature set-
ting items) at the indoor units in the displayed timer group where remote
controller prohibit is in effect.
(4) After checking the addresses and operating the units, press and hold
the
button for 2 seconds or longer. The schedule timer dis-
play returns to the normal display and all controllable indoor units stop.
Explanation to Customers

After work is completed, present the Operation Manual and
Information for the Person in Charge of Installation (Electrical) Work
to the customer.
Explain to the customer the methods for use of the system, as
described in the Operation Manual.
Installation Work Plan
Use the wired remote controller to check the unit No. of the indoor
units.
(Start the A/C unit with the wired remote controller, then press the
remote controller UNIT SELECT button once to display the unit
