SPECIAL WIRING SYSTEM

The special characteristics of these regulators enable
the remote control using conventional auxiliary pus-
hbuttons, making it possible to control the turning on
and off and regulation features from different points by
means of only one electronic device and any number
of conventional pushbuttons as desired.
In case it is required to exercise control from seve-
ral points, refer to the diagram below. Any number of
auxiliary conventional pushbuttons may be used as
needed. The outputs of these pushbuttons are con-
nected to terminal "1". See Figure 2.
NOTA: Pay special attention to the device input
and output conductors, according to the previous
description.
Make sure to disconnect the power supply before
manipulating the device.
