Operation

Features

Your garage door opener is equipped with features to provide you with greater control over your garage
door operation.
®
MyQ
®
MyQ technology uses a 900MHz signal to provide two-way communication between the garage door
®
opener and MyQ enabled accessories. Your garage door opener is compatible with up to 8 MyQ
accessories. For Smartphone App control of your garage door opener and other MyQ
®
Chamberlain's MyQ Internet Gateway (model CIGBU) is required.
TIMER-TO-CLOSE (TTC)
The Timer-to-Close feature automatically closes the garage door after a specified time period. DO NOT
enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors. Factory
default is set to off. The garage door opener will beep and the lights will flash before closing the door.
The TTC feature will deactivate if the garage door encounters an obstruction twice; or the safety reversing
sensors are incorrectly installed. The garage door will reverse open and WILL NOT close until the
obstructions are clear or the safety reversing sensors are correctly installed. When the obstruction has
been cleared or the safety reversing sensors have been aligned, the door will close when the garage
door opener is activated. TTC WILL NOT work if the garage door opener is operating by battery power or
if the safety reversing sensors are misaligned. This feature is NOT intended to be the primary method of
closing the door. A keyless entry should be installed in the event of an accidental lock out when
using this feature.
REMOTE CONTROLS AND DOOR CONTROLS (MyQ

control,which changes with each use, randomly accessing over 100 billion new codes. Compatible with

THE PROTECTOR SYSTEM
When properly connected and aligned, the safety reversing sensors will detect an obstruction in the path
of the infrared beam. If an obstruction breaks the infrared beam while the door is closing, the door will
stop and reverse to full open position, and the opener lights will flash 10 times. If the door is fully open,
and the safety reversing sensors are not installed, or are misaligned, the door will not close from a
® remote control. However, you can close the door if you hold the button on the door control or keyless
entry until the door is fully closed. The safety reversing sensors do not effect the opening cycle.
ENERGY CONSERVATION
For energy efficiency the garage door opener will enter sleep mode when the door is fully closed. The
sleep mode shuts the garage door opener down until activated. The sleep mode is sequenced with the
garage door opener light bulb; as the light bulb turns off the sensor LEDs will turn off and whenever the
garage door opener lights turn on the sensor LEDs will light. The garage door opener will not go into the
sleep mode until the garage door opener has completed 5 cycles upon power up.
LIGHTS
The garage door opener light bulbs will turn on when the opener is initially plugged in; power is restored
after interruption, or when the garage door opener is activated. The lights will turn off automatically after
4-1/2 minutes. An incandescent A19 light bulb (100 watt maximum) or for maximum energy efficiency a
26W (100W equivalent) compact fluorescent light (CFL) bulb may be used. NOTE: Do not use halogen,
short neck, or specialty light bulbs as these may overheat the end panel or light socket. Do not use LED
bulbs as they may reduce the range or performance of your remote controls.
NOTE: Do not use halogen, short neck, or specialty light bulbs as these may overheat the end panel or
light socket. Do not use LED bulbs as they may reduce the range or performance of your remote controls.
Light Feature
The garage door opener is equipped with an added feature; the lights will turn on when someone enters
through the open garage door and the safety reversing sensor infrared beam is broken. For added
control over the light bulbs on your garage door opener, see page 33.
