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.
●
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.
●
The length of the power wiring must be no more than 200 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.)
If a system controller is also installed:
Connect the wires for the schedule timer inter-unit control wiring (see
Note below) to the C1 and C2 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 C1 and C2.
●
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):

What is a timer group?
This is a group of indoor units, created by
dividing the central control addresses of the 64
indoor units that are connected to the inter-unit
control wiring, and assigning a timer program to
each group.

Central Control Main/Sub
Switching (4)
Sub: OFF
Main: ON
(1) Set to “sub” (OFF) when using together with the AMY
adapter, communications adapter, intelligent
controller, multi-controller, LON I/F, and system
controller.
(2) In cases other than (1) above, when using together
with an ON/OFF central controller, set to “main” (ON)
when only 1 schedule timer unit is used.
(3) In cases other than (1) above, and when using with
multiple schedule timer units, set only 1 unit to “main”
(ON) and set the remainder to “sub” (OFF).
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.
