Locate door control within sight of door, at a minimum height of 5 feet (1.5 m) where small
children cannot reach, away from moving parts of door and door hardware.
If installing into drywall, drill 5/32 inch holes and use the anchors provided. For pre-wired
installations (as in new home construction), control panel may be mounted to a single gang
box.
NOTE: The functional temperature range of the door control is between -4° F (-20° C) and
122° F (50° C). Scroll speed of display is slower at lower temperatures although the door
control remains fully functional.
CAUTION: Continuous exposure of the door control to temperatures below -22° F (-30° C)
may damage the LCD screen.
SPECIAL NOTE: Only one Smart Control Panel ® can be connected to each garage door
opener. If additional door controls are desired to operate the same garage door opener, it is
recommended to use model 378LMC wireless door control as the secondary door control.
Strip 7/16 inch (11 mm) of insulation from one end of bell wire and connect to the two
screw terminals on back of door control: white wire to W(2) and white/red wire
to R(1).
Remove push bar cover by gently prying at the lower/middle portion of the cover with
a small fl at-head screwdriver.
Fasten with 6AB x 1-1/4" self-tapping screws (drywall
installation) or 6-32 x 1" machine screws (into gang box) as follows:
Install bottom screw, allowing 1/8 inch (3 mm) to protrude above wall surface.
Position bottom of door control on screw head and slide down to secure. Adjust screw
for snug fi t.
Install top screw with care to avoid cracking plastic housing. DO NOT overtighten.
Replace cover by inserting top tabs fi rst and then snap cover in place.
(For standard installations ONLY) Run bell wire up wall and across ceiling to the
garage door opener. Use insulated staples to secure wire in several places. DO NOT
pierce wire with a staple, creating a short or open circuit.
Strip 7/16 inch (11 mm) of insulation from end of bell wire. Connect bell wire to the
quick-connect terminals on the garage door opener: white to white and white/red
to red.
Fasten the warning placard to the wall next to the door control.
NOTE: If you have any trouble with the operation of the buttons, loosen the top
mounting screw. DO NOT connect the power and operate the garage door opener at
this time. The door will travel to the full open position but will not return to the close
position until the sensor beams are connected and properly aligned. See page 15.
