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. When solder rolls off the tip, it needs cleaning.

• Thin raisin-core solder. Do not use any flux or grease.

• A diagonal cutter to t rim exc ess wires. To avoi d injury when cutting excess l eads, ho ld the le ad 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

* Typograp hical inac curacies excluded. Al ways look for possible last mi nute manual upda tes, indic ated as ‘NOTE’ on a s eparat e leaflet.

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 !

AXIAL COMPONENTS ARE TAPED IN THE

CORRECT MOUNTING SEQUENCE !

Push once to turn on, push again to turn off th e load. Applications : put a virtually unlimited num­ber of pushbut tons i n parallel to control a light sou rce or other device.

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.
Applicat ions : G eneral timing. Hint : use as ‘Toggle mode’ wi th a very lo ng dela y tim e. This will
ensure lights will not remain on forever if forgotten to turn them off.

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, bas ements, stor age rooms, fr ont door lig ht­ing, …

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 push button is held down.
Applicat ions : same as above, but allows to select a longer time if necessar y.

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. Applications :
General timing.

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, dri veways, …

turn on with delay1*. W hen time elapses, loa d is tur ned o ff and delay2* is en abled. 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, airc o, TV,
spa, …

Push to turn on load . When butto n is rel eased, timer is star ted. W hen time ela pses, load is
turned of f. Repeated push during on-time restarts timer. Appli cations : Allow a pump or fan to
remain on for a while after a sensor detects pre-set level, to prevent cycling.

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,

As long as th e button is pushed, the load is turned on and off wit h a fixed frequency of 1Hz.
Applicat ions : warning lights , buzzers, …

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.
Applicat ions : warning lights , buzzers, …

As long as the button is closed, the system will activate the output in a random manner (9 min­utes to 2.5 h between every transitio n). Initial load sta tus at acti vation is also determined at
random.
Applicat ions : Simulate presence a t home during absence

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-tim e will restart
the timer at release of the button.
Applications : Ventilation of restrooms, restroom flush control, …

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

(*) The learning mode allows you to fi x the duration of delay1 and delay2. See further for
instructions on how to use this mode.

Operating mode & Learning mode

21. 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, del ay1 has been factor y set to 3 minutes, whi le 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 pow er failure. T o change the default delays, flip all dipswitc hes SW1 to the ON- positi on.

First, you store delay1:

Push the button once. (The load bli nks 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 recordi ng 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 bli nks 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 st opping the recording
The load will blink twice to confirm the recorded tim e
Hint : Should you wish to change delay2, without changing delay1, simply enter a short ‘dummy’ tim e for delay1, without
confirming it. Then you can proceed with delay2.
