Operating Modes
The MASTERFUN Automatic Chicken Coop Door offers two operating modes: Timer Mode and Manual Mode.
1. Timer Mode
Timer mode allows you to set specific times for the door to open and close automatically each day. This provides convenience and ensures your flock is secured at consistent times.
- Access Settings: On the large LCD screen, locate the "OPEN" and "CLOSE" time settings.
- Set Open Time: Use the control buttons (usually indicated by arrows or specific symbols) to adjust the desired opening time.
- Set Close Time: Similarly, adjust the desired closing time.
- Confirm Settings: Ensure your settings are saved or confirmed according to the on-screen prompts. The door will now operate automatically based on these times.

2. Manual Mode
Manual mode allows you to open or close the door instantly at any time, overriding the timer settings. This is useful for specific situations or immediate access.
- Manual Open/Close: Press the designated manual open or close button on the control panel. The door will immediately respond to your command.
Anti-Pinch Safety Mechanism
The MASTERFUN Automatic Chicken Coop Door is equipped with an advanced anti-pinch safety feature to protect your chickens from injury during closing. This mechanism operates as follows:
- If the door detects an obstruction (e.g., a chicken) during its closing cycle, it will immediately stop and lift slightly.
- The door will pause for approximately 13 seconds.
- If the obstruction is still present after 13 seconds, the door will retract fully, wait for 10 seconds, and then attempt to close again.
- This cycle repeats until the path is clear, ensuring the safety of your flock.

Battery Installation and Replacement
The chicken coop door is powered by 3 x AA alkaline batteries (not included). The battery life is approximately 6 months under normal usage conditions.
- Locate Battery Compartment: The battery compartment is typically located on the back or side of the control unit.
- Open Compartment: Use a screwdriver or your fingers to open the battery compartment cover.
- Insert Batteries: Insert 3 x AA alkaline batteries, paying close attention to the correct positive (+) and negative (-) polarity markings inside the compartment.
- Close Compartment: Securely close the battery compartment cover.
- Battery Replacement: When the battery indicator on the LCD screen shows low power, replace all three batteries simultaneously with new AA alkaline batteries.
