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 oftenon 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 goodconnections. When solder rolls off the tip, it needs cleaning.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they
cannot fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• Small blade and Phillips screwdrivers. A basic range is fine.
For some projects, a basic multi-meter is required, or might be handy
1.2 Assembly Hints :
⇒ Make sure the skill level matches your experience, to avoid disappointments.
⇒ Follow the instructions carefully. Read and understand the entire step before you perform each operation.
⇒ Perform the assembly in the correct order as stated in this manual
⇒ Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
⇒ Values on the circuit diagram are subject to changes.
⇒ Values in this assembly guide are correct*
⇒ Use the check-boxes to mark your progress.
⇒ Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute manual updates,indicated as ‘NOTE’ on a separateleaflet.

Assembly hints
1.3 Soldering Hints :
1- Mount the component against the PCB surface and carefully solder the leads
2- Make sure the solder joints are cone-shaped and shiny
3- Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE ONE AT A TIME !

The unit is equipped with a transient suppressor to reduce contact
wear. With very small loads, it might be necessary to omit the shunt.

Operating mode

SW1 OPERATION
MODE DESCRIPTION
Momentary
mode The load will be switched on as long as the pushbutton is pressed.
Applications : doorbell, …
Toggle mode Push once to turn on, push again to turn off the load. Applications : put a virtually unlimited num-
ber of pushbuttons in parallel to control a light source or other device.
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 a very long delay time. This will
ensure lights will not remain on forever if forgotten to turn them off.
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 light-
ing, …
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 retrigger 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.

9
Operating mode
Non-retrigger-
able timer
Push to turn on. After pre-set time has elapsed, load will turn off. Pushing the button during on-time
has noeffect. Load will turn off when pushbutton is held down andtime elapses. Applications :
General timing.
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, …
Timer with
early re-trigger
prevention
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, airco, TV,
spa, …
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.
Interval timer As long as the button is pushed, the load will be turned on during delay1*, and turned off during
delay2* Applications : Lawn sprinklers, pool pumps, compressor dehydration, ventilation, defrost-
ing,
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, …

10
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, …
Random timer
As long as the button is closed, the system will activate the output in a random manner (9 min-
utes to 2.5h between every transition). Initial load status at activation is also determined at
random.
Applications : Simulate presence at home during absence
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, restroom flush control, …
Interruptible
Real Time
staircase timer
Press briefly to activate interval 1, a prolonged push will activate interval 2. The charge will
be neutralised after the interval, even if the button remains pressed down. Pressing the
button briefly while the charge is activated will immediately neutralise this charge.
applications : staircase light control, attics, basements, stores and warehouses
Learning
mode (*) The learning mode allows you to fix the duration of delay1 and delay2. See further for instructions on how to use this mode.
Operating mode

11
Operating mode & Learning mode
The learning mode allows you to store two different delays, each from 2s 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 dipswitches 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
To confirm the recorded 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
To confirm the recorded 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.
