5. Setup and Installation
Proper installation is crucial for the reliable operation of your code keypad. Ensure all safety instructions are followed.
5.1 Mounting the Keypad and Control Unit
- Choose Location: Select a suitable outdoor location for the keypad, ensuring it is easily accessible but protected from direct impact. The control unit should be mounted securely indoors or in a protected outdoor enclosure.
- Mark Drilling Points: Use the keypad and control unit as templates to mark the drilling points for mounting screws.
- Drill Holes: Drill holes at the marked points and insert appropriate wall anchors if necessary.
- Secure Units: Mount the keypad and control unit firmly using the provided screws.
5.2 Electrical Connection
The CTR1D Code Keypad requires a 24 V AC/DC power supply. A power supply cable is not included. The connection to your garage door operator or gate system is made via the relay control unit.
- Power Supply (24 V AC/DC): Connect the 24 V AC/DC power supply to the designated terminals on the relay control unit. Refer to the wiring diagram provided with your specific garage door operator for exact terminal identification.
- Keypad to Control Unit: Connect the keypad to the relay control unit using the appropriate cable. Ensure correct polarity if specified.
- Impulse Connection (Relay Output): The relay output from the control unit connects to the impulse input of your garage door operator. For Hormann Supramatic 3 operators, connect the impulse terminals on the relay control unit (typically the extreme right terminals) to terminals 20 and 21 on the Supramatic 3 motor.
- Common Ground/Power for Supramatic 3: For Supramatic 3 operators, connect the power supply terminals (24V DC/AC) on the relay control unit to terminals 20 and 5 on the Supramatic 3 motor.
- Secure Connections: Ensure all cable glands are tightened to maintain weather resistance.
Note: The specific wiring terminals may vary depending on your garage door operator model. Always consult the instruction manual of your garage door operator for precise wiring diagrams. If you are unsure, consult a qualified technician.

8. Troubleshooting
If you encounter issues with your CTR1D Code Keypad, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Keypad does not respond. | No power supply; incorrect wiring; faulty unit. | Check 24 V AC/DC power connection to the control unit. Verify all wiring connections are secure and correct. If issues persist, contact support. |
| Garage door/gate does not open/close. | Incorrect access code; incorrect impulse wiring; issue with garage door operator. | Ensure the correct access code is entered. Verify the impulse connection between the control unit and the garage door operator (e.g., terminals 20 and 21 for Supramatic 3). Check the garage door operator's functionality independently. |
| Keypad programming fails. | Incorrect programming steps; existing master code issue. | Review the programming instructions carefully. Ensure you are in the correct programming mode. If a master code is required, ensure it is entered correctly. |
| No backlight on keypad. | The CTR1D model does not feature keypad backlighting. | This is not a malfunction. The Hormann CTR1D model does not include an illuminated keypad. |
