Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’and will protect the tip, and enables you to make good connections.

Entering the code (5) ENTER YOUR CODE At first turn-on, the unit responds to factory code (1 - 0 - 1 - 0) only. To compose the code: 1) 2) 3) 4) 5) turn clockwise to 1 turn counter clockwise to 0 turn clockwise to 1 turn counter clockwise to 0 turn clockwise if you make a mistake, restart from 1 The relay turns on and the 'lock open'-symbol is displayed.
Menu options (6) MENU OPTIONS Remark: you can only access the menu when the output relay is off Hold the button to enter the setup menu The display shows '-'. If button is released at this time, no settings will be altered. The decimal dot will flash 3 times, to confirm you left the menu. If the unit was set to ‘timer mode’, the display will flash the current set time. Turn knob in any direction to select a menu item, while still holding the button.
Menu options 'c' continuous mode : The output relay remains activated until the knob is turned. To set continuous mode: Release button Decimal point will flash 3 times to confirm selection 's' Set mode : Allows you to compose a 4-digit code of your choice. To select 'set' mode: Release the menu button Compose your custom 4-digit code (change direction after each digit and last digit). The decimal point will flash 3 times to indicate that your code has been stored.
Menu options 'I' Relay turns on at power up You have 1 min to enter your code (Display shows an animation) Compose your code If the correct code is not entered within one minute, the relay will turn off and 'A' (alarm) will flash. Release the menu button to select this mode Decimal point will flash 3 times to confirm selection 'o' Relay is off at power up. You have 1 min to enter your code.
