Wiring the Schedule Timer
● Before beginning wiring
– Use 0.5 – 2 mm
2
wires for field supply wiring.
– For inter-unit control wiring, use signal wires that
allow the remote controller wiring to be differentiat-
ed 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. 3-46)
<Basic Wiring Diagram>
●
Route the A/C inter-unit control wiring for central
control as shown in the figure at right.
●
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 connected is 8. (A maximum of 10 schedule
timer units and other central control devices can be
connected.)
<Note> Depending on the model of A/C, a local adapter
may be required.
