Wiring the Schedule Timer
Before beginning wiring
– Use0.5–2mm
2wires for field supply wiring.
–
–
For inter-unit control wiring, use signal wires that allow the
remote controller wiring to be differentiated from the power
wiring, and take care to prevent miswiring. (Miswiring will
damage the schedule timer.)
– Check that the schedule timer communications wiring and
power wiring are connected correctly. (Fig. 5)
<Basic Wiring Diagram>
Route the A/C inter-unit control wiring for central control as
shown in the figure below.
The maximum number of indoor units that can be connected to
a single system is 64. The maximum number of outdoor units is
30.
The maximum number of schedule timer units that can be con-
nected is 8. (A maximum of 10 schedule timer units and other
central control devices can be connected.)
WARNING
CAUTION

Installing the Schedule Timer
<Note 1> Avoid twisting the inter-unit control wiring or the input/out-
put wiring together with power or other wiring, and avoid
running them in the same metal conduit. Doing so can
cause malfunction.
<Note 2> Install the schedule timer at a location away from any
sources of electrical noise.
<Note 3> Install a noise filter or take other appropriate action if elec-
trical noise affects the power supply circuit of the unit.
(1) Open the panel on the schedule timer unit. Insert a standard (flat-
head) screwdriver or similar tool into the notches on the bottom of
the schedule timer unit to open and remove the back case.
(2) Use the 2 supplied M4 small screws and install the schedule
timer back case onto the switch box. Before installing, use a
screwdriver or similar tool to press on and open the screw holes
that correspond to the Electric jinction box that is used.
When fastening the case, use spacers and do not tighten the
screws too much. If the schedule timer does not fit tightly against
the wall, cut the spacers as required to make adjustments.
(3) Connect the supplied power wire (2-core) and inter-unit control
wire (3-core) to the schedule timer unit.
(Refer to “Wiring the Schedule Timer.”)
(4) Align the schedule timer unit with the tabs on the back case and
press to install it.
Installation of connected schedule timers
When installing schedule timers (remote controller switches, system
controllers, etc.) onto the wall, use the method shown in Figs. 3 and 4.
If power is supplied from the indoor unit control PCB of a nearby
indoor unit, connect the provided T10 terminal connection wires to
the T10 terminal on the indoor unit control PCB, and to the sched-
ule timer power wires.
The inter-unit control wiring has no polarity. The wiring may be
connected in either direction to U1 and U2. (Use shielded wiring)
If necessary, use a relay wire when connecting the wiring to the
indoor unit control PCB.
The power wiring has no polarity. The wiring may be connected
in reverse. (Use shielded wiring)
The length of the power wiring must be no more than 100 m.
<Note> The only functions of the schedule timer are indoor unit
ON/OFF and remote controller enable/disable operations. It
is therefore recommended that during installation, a sys-
tem controller, remote controller, or similar device be
installed next to the schedule timer so that the operation
mode and other information can be checked.
(If the system controller or other central control device is not
present, the schedule timer cannot be used in combination
with a system that does not utilize remote controllers.)
Wiring
The schedule timer wiring can be connected by the following two
methods. Select one of these connection methods according to the
actual installation location.
When wiring, extend the lengths of the wires using wire joints (pro-
vided) and extension wires (field supply).
When installing multiple schedule timers,
avoid the use of cross-over wiring.
Connection diagram (Be sure to use the provided wires as the
power wiring.)
If a system controller is also installed:
Connect the wires for the schedule timer inter-unit control wiring (see
Note below) to the U1 and U2 terminals on the system controller ter-
minal board. Connect the system controller power wiring to CN02
and to the schedule timer power wires (white + black).
The inter-unit control wiring has no polarity. The wiring may be
connected in either direction to U1 and U2. (Use shielded wiring)
The power wiring has no polarity. The wiring may be connected in
reverse.
The length of the power wiring must be no more than 100 m.
Note: The inter-unit control wires are pink + blue + blue (using
wire joint crimping). Use pink + blue wires.
If a system controller is not installed (power is supplied from
the indoor unit):
<Note> Depending on the model of A/C, a local adapter may be
required.

About the Setting Switches
Complete the switch settings before turning ON the schedule timer
power.
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.)
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
No. of the master unit.)
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.
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 button, button,
and CLEAR button for 4 seconds or longer. “Ad-(central control
address)” appears in sequence, blinking.
(2) Use the GROUP button in the area to display the blinking central
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 but-
ton. Each time the button is pressed the indoor units in the displayed
timer group start or stop. Pressing the button in this mode
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.
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
after several minutes, and the timer group settings are confirmed.
Procedure for making manual timer group settings (manual
group assignments)
Manual timer group settings allow central control addresses to be assigned
freely within the timer groups.
(1) Turn ON S41 setting switches 2 and 3, then turn ON the power. Restart
and initial communications are performed. (SCAn blinks in the display.)
The normal display appears after several minutes.
(2) When the normal display appears, press and hold the schedule timer
button, the timer button, and the button for 4
seconds or longer. “Ad-01” appears, blinking, in the current time display.
(Ad indicates “address” and 01 is the central address number.)
(3) Use the button in the area to select the timer group. Then
use the button in the area to select the central control address
to assign and register for that timer group. Press the button
to register the selected central control address.
(4) To continue registering addresses, repeat step (3). (Central control
address numbers will be added to the right side of the LCD display.) To
cancel a registered central control address, use the button in
the area to select the timer group, then use the button in the
area to select the central control address and press the button.
(5) Repeat steps (3) – (4) for each timer group. When registration is com-
pleted, press the timer button. The schedule timer restarts
automatically and performs initial communications. (SCAN blinks in the
display.) The normal display appears after several minutes, and the
manually assigned timer group settings are confirmed.
