The weekend opening time setting then appears, followed finally by the weekend closing
time setting. The times for the weekend can be identified by a dot at the end of the time.
8.2.2 Automatic return to automatic mode
The next menu item to appear in the display is AC OFF or AC ON. Change the setting
with the arrow keys. If the function is activated (AC ON), the control unit independently
engages automatic mode in the next day cycle, even if you had interrupted automatic
mode with a manual movement of the door. You can exit the menu with the Menu button.
8.2.3 Activating automatic mode
To activate the automatic mode, press the Up key when the door is open or the Down key
when the door is closed. Automatic mode is indicated by a small circle at the top side of
the display.
8.2.4 Deactivating the timer
If you want to operate the automatic mode with the light sensor only (see section 8.3),
then you can deactivate the timer by pressing the menu and OK button at the same time.
The display will show 't-off'. Repeat this process if you want to reactivate the timer.
The display will then show the current time.
8.3 Using the light sensor
To make automatic opening and closing dependent on the ambient brightness, connect the supplied light sensor with the device and position
the sensor in a suitable place. Ensure that the sensor is easily able to detect daylight. The sensor must not be influenced by other sources of
light (e.g. artificial light from a street lamp or from a house window). Do not position the sensor on roadways where light from the headlights
of passing cars may influence the sensor. Please note that approx. one minute may elapse before the light sensor responds to a change in
brightness. This prevents accidental opening of the door in the event of lightning.
If automatic mode is activated, the door is opened and closed when the set brightness level is reached. The opening and closing times of the
timer (see section 8.2) remain active even when using the light sensor. The following applies:
• If the set closing time is reached, the door is always closed
even if the light sensor still detects sufficient brightness.
• If the set opening time is reached, the door will remain closed until the light sensor has detected sufficient brightness.
The sensor's switching threshold can be adjusted via the menu. Here, the controller detects the current brightness level, and opens or closes at
this brightness from now on.
It is recommended that the brightness level is set in the evening. After all chickens have returned to the coop of their own accord, you should wait
about 10 to 15 minutes, and reset the threshold value. To do this, proceed as follows:
Press "OK" briefly three times to set the threshold value of the light sensor.
The display now shows
Press "OK" again to save the current brightness level. The controller detects the current
brightness, and from now on closes or opens at the newly set brightness level.
After the setting has been made, the door opens or closes immediately.
If a light sensor is not connected, this error message appears in the display
The door should then close or open immediately.
