DIP SWITCH	OPERATION MODE	DESCRIPTION
0 0 0 0	Momentary mode	The load will be switched on as long as the pushbutton is pressed. Application: Doorbell
1 0 0 0	Toggle mode	Push once to turn on, push again to turn off the load. Applications: put a virtually unlimited number of pushbuttons in parallel to control a light source or other device.
0 1 0 0	Start/stop timer	Push to turn on. After pre-set time has elapsed. load will turn off. Push any time to turn off. Load will turn off when pushbutton is held down and time elapses. Applications: General timing. Hint: use as 'Toggle mode' with very long delay time. This will ensure lights will not remain on forever if forgotten to turn them off.
1 1 0 0	Staircase timer	Push to turn on. After pre-set time has elapsed, load will turn off. A push during on-time will restart timer and stretch on-time. Applications: staircases, basements, storage rooms, front door lighting.
0 0 1 0	Dual - time staircase timer	A short push turns on with delay1* while a longer push turns on with delay2. Repeated short/long pushing during on-time will re-trigger timer accordingly. Load will turn off when time elapses even when pushbutton is held down. Applications:* same as above, but allows to select a longer time if necessary.
1 0 1 0	Non re-triggerable timer	Push to turn on. After pre-set time has elapsed. load will turn off. Pushing the button during on-time has no effect. Load will turn off when pushbutton is held down and time elapses. Application: General timing
0 1 1 0	Turn - on delay	Turn on delay starts when button is pushed. When time elapses, load is turned on until button is released. Applications: Prevent cycling of light sources operated by a motion detector on porches, front doors, driveways.
1 1 1 0	Timer with early re-trigger prevention	Push to turn on with delay1. When time elapses, load is turned off and delay2 is enabled. Load cannot be turned on again before delay2 elapses. Continuous pushing will not switch on the load when delay2 elapses. Applications: Prohibit continuous operation of heating, A/C, TV, spa...
0 0 0 1	Turn - off delay	Push to turn on load. When button is released, timer is started. When time elapses, load is turned off. Repeated push during on-time restarts timer. Applications: Allow a pump or fan to remain on for a while after a sensor detects pre-set level to prevent cycling.
1 0 0 1	Interval timer	As long as the button is pushed, the load will remain on during delay1, and turned off during delay2. Applications: Lawn sprinklers, pool pumps, compressor dehydration, ventilation, defrosting...
0 1 0 1	Blinking circuit	As long as the button is pushed, the load is turned on and off with a fixed frequency of 1Hz. Applications: warning lights, buzzers...
1 1 0 1	Blinking circuit with timer	Push to start the blinking action as described above. At release, the timer will start. When time elapses, the load is turned off. A push during on-time restarts the timer. Applications: warning lights, buzzers...
0 0 1 1	Random timer	As long as the button is closed, the system will activate the output in a random manner. (9 minutes to 2.5 hours between every transition). Initial load status at activation is also determined at random. Applications: simulate presence at home during absence.
1 0 1 1	Trigger - at - release timer	The load will be turned on when the pushbutton is released. At release, the timer is started. When time elapses, output is turned off. Pushing again during on-time will restart the timer at release of the button. Applications: Ventilation of restrooms
0 1 1 1	Reset default times	If you have changed the duration of delay1 and delay2, you can restore their default values (i.e. delay1 = 3 minutes and delay2 = 30 minutes) by entering this mode and pressing the button briefly to confirm. Entering the mode without pressing the button will not erase the delay times.
1 1 1 1	Learning mode	(*) The learning mode allows you to fix the duration of delay1 and delay2. See further instructions on how to use this mode.

LEARNING MODE
The learning mode allows you to store different delays, each from 2 up to 12 days. The delays are called delay1 and delay2. Originally, delay1 has been factory set to 3 minutes, while delay2 has been set to 30 minutes. All timer modes use delay1 unless the mode uses both delays. You can change these delays to suit your needs. The new delays are stored in EEPROM and will be kept in case of a power failure. To change the default delays, flip all dip switches SW1 to the ON position. First, you store delay1:
Push the button once
The load blinks once and turns on
The recording starts
Wait until the desired time has elapsed
Push the button again to stop recording
The load is turned off and the recording stops
The load will blink once
The confirm the record time, press the button briefly within 5 seconds after stopping the recording
The load will blink once to confirm the recorded time

Then you can store delay2
Push the button once
The load blinks twice and turns on
The recording starts
Wait until the desired time has elapsed
Push the button again to stop recording
The load will blink twice
The confirm the record time, press the button briefly within 5 seconds after stopping the recording
The load will blink twice to confirm the recorded time
HINT: Should you wish to change delay2 without changing delay1, simply enter a short 'dummy' time for delay1 without confirming it. Then you can proceed with delay2.
