Operation modes 

 

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. 

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, …
