The low voltage control (LVC) housing is divided into 3 compartments. the compartment labeled “Low Voltage
Connections” is where you will connect the wall switch or a central control panel. The compartment labeled “AC Power
Connections” is where the main power and motor wire connections are made. The center compartment only requires
access when connecting an infrared or radio frequency remote receiver.
INSTALLATION
WARNING: To prevent electrical shock or damage to the LVC, do not apply power to the LVC until all connections are
complete. Make sure power is turned off on all wires before making connections.
LOW VOLTAGE CONNECTIONS:
Wall Switch
WARNING: This unit must be used with the enclosed switch. DO NOT USE the rocker switch included with screen.
1. Install wall switch where desired.
2. Use 3-conductor 20-24 gauge wire to extend the switch wire to the required length.
3. Connect the wire from the switch to the wire labeled “wall switch”. Refer to diagram 1.
CAUTION: Never apply voltage to the wall switch lead or the LVC will be damaged.

s
Control Panel
A control panel may be connected to the LVC by using the wall switch wire lead. The control panel must provide a
momentary, dry contact closure of at least 1/2 second.
1. Use 3-conductor 20-24 gauge wire to connect the control panel to the wall switch lead.
2. A momentary closure across the white and red wires will be an “up” command.
3. A momentary closure across the white and black wires will be a “down” command.
4. A momentary closure across the white, red and black wires will be a “stop” command.
CAUTION: Never apply voltage to the wall switch lead or the LVC will be damaged.

SYMPTOM
1. Screen will not operate.
(b)
(d)
2. Radio frequency remote does not
work.
3. Infrared remote does not work.
b
c
4. Screen runs in the wrong
direction.
CAUSE
(a) No power to LVC unit.
(b) Incorrect wiring.
(c) Low voltage circuit damaged due
to voltage input.
(d) LVC controller lock-up
(a) Weak battery in transmitter.
(a) Weak battery in transmitter.
(b) Receiver incorrectly positioned.
(c) Fluorescent light interference.
(a) Red and black wires are reversed
on motor or wall switch
terminals.
SOLUTION
(a) Turn on power to LVC input.
Measure voltage across black
and white input leads.
(b) Recheck all wiring for proper
installation. Check all wire nut
connections.
(c) The wall switch terminal is for
dry contact (no voltage) input
only. Applying voltage to this
terminal will damage the LVC.
(d) Locate breaker for screen and
turn off power. Wait one minute
and re-activate circuit.
(a) Replace battery.
(a) Replace battery.
(b) Receiver must be unobstructed
and located in direct line with the
transmitter.
(c) Remote receiver should not be
placed near fluorescent lights.
(a) Turn off power to LVC. Reverse
the red and black wires on either
the motor terminals or the wall
switch terminals. Changing either
one will change the direction of
motor travel. Do not change
both.
NOTE: The LVC will shut off power to the screen motor 5 minutes after the motor stops turning. Push the up or down button to
reactivate the LVC relays.
