Function 14: Learning mode
The learning mode enables the time periods DELAY1 and DELAY2 to be set. When this function has
been selected, LD4 will flash slowly. Now keep the pushbutton on the PCB (SW1) pressed in, LD3 will
light up as an indication. When SW1 is released, the first period (DELAY1) starts to register.
LD2 and LD3 now flash alternately to indicate that the registration clock is running. Now wait until the
desired time has lapsed. Briefly press again on SW1 in order to stop registration, LD2 alone will then
flash.
To confirm the registered time press the pushbutton SW1 again (within 10 seconds of registration
stopping) until LD1 lights up. The registered time is then saved to the EEPROM memory.
If you make a mistake, or only want to change DELAY2,then let the 10 seconds lapse without
pressing any buttons.
After setting DELAY1 you proceed in the same way for DELAY2:
Keep the pushbutton on the PCB (SW1) pressed in, LD3 will light up as an indication.
When SW1 is released, registration of the second period begins (DELAY2). LD2 and LD3 now flash
alternately to indicate that the registration clock is running. Now wait until the desired time has lapsed.
Briefly press on SW1 again in order to stop registration, LD2 alone will then flash. In order to confirm the
registered time you have to press the pushbutton SW1 again (within 10 seconds of registration stopping)
until LD1 lights up. The registered time is then saved in the EEPROM memory. After the setting, the last
chosen function starts up again, taking account of any newly stored delay times.
