Product Description
The MONOPLEX Sofa Controller is intended to be used in conversion vehicles to con-
trol the operation of a two-way or four-way, slide recline power sofa. It allows easy wir-
ing of multiple switches and provides electronic shutdown at the end of travel to prevent
annoying circuit breaker or fuse openings.
By utilizing the MONOPLEX System, only one light-gauge wire and ground are needed
to connect the multiple switches. The control is located near the sofa so the four motor
wires can easily be connected to it. A single 12-gauge wire feeds power to the control
from the fuse block.
To operate the sofa, the three position, momentary rocker is pressed and held in the di-
rection of the function desired (slide or recline). If the direction is wrong, the switch is
released and pressed again. After the sofa has reached its desired position, the switch
is released. If it is held until the sofa reaches it’s mechanical stops, the control will
automatically shut off the power. This feature helps prevent damage to the sofa if it is
operated under a load such as someone sitting on it.
