Setup and Installation

This section guides you through the physical installation and initial programming of your wall control panel.

Mounting the Wall Control Panel:

The 935CB wall control panel is designed for wall-mount installation inside your garage. Choose a location that is easily accessible and allows the motion sensor to detect movement effectively, typically near the garage entry door to your home.

It is positioned to the right of a doorway leading into the house, with various garage organization items like a hose, rake, and ladder visible in the background. This placement allows for convenient access and motion detection.

1. Power Disconnection: Before beginning installation, ensure the power to your garage door opener is disconnected at the circuit breaker to prevent accidental operation.
2. Wire Connection: Connect the low-voltage wires from your garage door opener to the terminals on the back of the 935CB wall control panel. Follow the wiring diagram provided with your garage door opener for correct connections.
3. Mounting: Secure the wall control panel to the wall using the provided screws. Ensure it is mounted at a height that is easily accessible for all users and allows for optimal motion detection.
4. Power Reconnection: Once securely mounted and wired, restore power to your garage door opener.

Programming a Remote Control (if applicable):

To program a Chamberlain remote control using the 935CB wall control panel, follow these steps:

1. Identify Buttons: On the 935CB wall control, locate the main door button and the light button. On your remote, identify the button you wish to program.
2. Initiate Programming: Simultaneously press and hold the desired button on your remote control, the light button on the wall control, and the main door button on the wall control.
3. Release Buttons: Continue holding all three buttons until you hear a click from the wall control or see its light blink (if applicable). This indicates successful programming.

Operating Instructions

Using the Motion Detection Feature:

The built-in PIR sensor automatically turns on the garage door opener lights when it detects movement within its 150-degree sensing angle. This feature provides hands-free illumination as you enter the garage.

• Activation: Simply walk into the garage, and the motion sensor will detect your presence, turning on the opener lights.
• Deactivation: The lights will remain on for the duration set by the adjustable light timer (see below) and then automatically turn off if no further motion is detected.

Operating the Garage Door:

To open or close your garage door manually using the wall control:

• Main Push Button: Press the large, illuminated push button on the wall control panel. This will activate your garage door opener, causing the door to open or close.

Adjusting the Light Timer:

The 935CB allows you to adjust how long the garage door opener lights stay on after activation. Refer to your garage door opener's manual for specific instructions on adjusting this timer, as the wall control typically sends a signal to the opener for this function.

Maintenance

Regular maintenance ensures optimal performance and longevity of your wall control panel.

• Cleaning: Periodically wipe the surface of the wall control panel with a soft, dry cloth to remove dust and debris. Avoid using abrasive cleaners or solvents.
• Battery: This wall control panel is corded electric and does not require batteries for its primary function. However, if your remote control uses batteries, ensure they are replaced as needed.
• Sensor Obstruction: Ensure the motion sensor lens is clear of obstructions (e.g., cobwebs, dust buildup) to maintain accurate motion detection.

Troubleshooting

If you encounter issues with your Chamberlain 935CB wall control panel, refer to the following common troubleshooting steps:

• Lights Not Activating with Motion:
  • Check for obstructions in front of the motion sensor.
  • Ensure the wall control is properly wired and receiving power.
  • Verify compatibility with your garage door opener model.
• Garage Door Not Responding to Push Button:
  • Confirm the wall control is securely connected to the garage door opener wiring.
  • Check the power supply to the garage door opener itself.
  • Inspect wiring for any damage or loose connections.
• Remote Control Not Programming:
  • Ensure you are holding all three specified buttons simultaneously for the required duration.
