The K8015 SELF-ASSEMBLY electronic kit provides 14 different timing functions including delay timers, switching, flashing, interval, random switching, etc (see Timing Modes info sheet for full details).
Comes with two pre-programmed delays (Delay1 = 3 min, Delay2 = 30 min). A learning-mode allows you to set each delay time from 2s up to 12 days. Delay times are stored in EEPROM memory so are kept in case of power loss.
Screw terminal blocks for power input, relay and external control pushbutton (not included). On-board optional transient suppressors included for the relay contacts.
Suitable for control of incandescent lighting, halogen lighting, fluorescent lighting, fans, valves, buzzers and more.Operation Modes
|Momentary||None||The load will be switched on as long as the pushbutton is pressed||Doorbell|
|Toggle||None||Push once to turn on, push again to turn off the load||Put a virtually unlimited number of pushbuttons in parallel to control a light source or other device|
|Start/Stop timer||Delay1||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. 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||retriggerable Delay1||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, etc.|
|Dual-time staircase timer||short press = Delay1; long press = Delay2||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-retriggerable timer||Delay1||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||Delay1||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, etc.|
|Timer with early re-trigger prevention||Delay1 and Delay2||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, airco, TV, spa, movement sensor, etc.|
|Turn-off delay||retriggerable Delay1||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 (cyclical) timer||Delay1 and Delay2||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, etc.|
|Blinking circuit||fixed frequency of 1Hz||As long as the button is pushed, the load is turned on and off with a fixed frequency of 1Hz||warning lights, buzzers, etc.|
|Blinking circuit with timer||fixed frequency of 1Hz plus Delay1||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, etc.|
|Random interval timer||9 min to 2.5h between every transition||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||retriggerable Delay1||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, restroom flush control, etc.|
|Interruptible real time staircase timer||short press = Delay1; long press = Delay2||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 warehouses|
