Description

Applications

Momentary Action

The load will be switched on as long as the pushbutton is pressed.

Doorbell

Toggle Action

Push once to turn on, push again to turn off the load.

You can put a virtually unlimited number of pushbuttons in parallel to control a light source or other device

Start/Stop

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.

General timing. 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.

Staircases, basements, storage rooms, front door lighting.

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.

Same as above, but allows to select a longer time if necessary.

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 no effect. Load will turn off when pushbutton is held down and time elapses.

General timing.

Turn-on delay

Turn on delay starts when button is pushed. When time elapses, load is turned on until
button is released.

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.

Prohibit continuous operation of heating, air conditioning, TV, spa, etc.

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.

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*

Lawn sprinklers, pool pumps, compressor dehydration, ventilation, defrosting,

Blinking circuit

As long as the button is pushed, the load is turned on and off with a fixed frequency of 1Hz.

Warning lights, buzzers ...

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.

Warning lights, buzzers..

Random timer

As long as the button is closed, the system will activate the output in a random manner (9 minutes to 2.5h between every transition). Initial load status at activation is also determined at random.

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.

Ventilation of restrooms, rest room flush control.

Interruptible
Real Time
staircase time

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.

Staircase light control, attics, basements, stores and warehouse

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
