Wiring the Schedule Timer

– Use 0.5 – 2 mm
– 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. 3-73)
