Wiring the Schedule Timer

Before beginning wiring

2
– Use 0.5 – 2 mm 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.
