  • Maximum number of timed events 7.

  • 1 switched output.

  • 1 event on LED indicator.

  • 1 button for event and time programming.


At initial power up, the time is set for midnight (0:00) and the 'on' time events will display 7?:00. The 'off' events will show 00:00. The seconds will be running.


Each menu option has a timeout period of approximately 20 seconds, before returning to the default screen, the top line of the display will show the current time, and on the second line the next programmed event time.


The clock is a 12 hour clock, midday is shown as 12:00 and midnight as 00:00

The switch, on and off times display alternately every 4 seconds.

Holding the button down for 1 second or more will advance the menu options .

The menus cycle around.

To set the time, the button is pressed for approximately half a second.

Loss of power will result in all settings being lost.

To enter the time or programmed times a press and hold of the button will advance the menu. A short press will increment the menu choice. Each menu choice waits for a button press for 20 seconds before returning to the default screen. The menu can only be advanced, and cycles through all options before returning to the default screen.


Press and hold the button.


The LCD will display the word Set on the left of the lower line on the LCD, and the word HOUR


A short press of the button will now increment the current time (hour) , at switch on the hour will be at 00 ie: Midnight.


Press and hold the button.


Menu will increment to Set MIN continue as above. Note that the seconds are reset on each increment.


Press and hold the button.


Menu will change to Set +HR the lower line will change to display


SET +HR 00 Ev x


A short press of the button will increment the programmed on hour time for event no (1....7).


The menu cycles in the following order:


Set HOUR sets the current time (hour)

Set MIN sets the current time (minute)

Set +HR Ev sets the progam ON time (hour) for event Ev (x) where x = 1..7

Set +MN Ev sets the program ON time (minute) for event Ev (x)

Set -HR Ev sets the program OFF time (hour) for event Ev (x)

Set -MN Ev sets the program OFF time (minutes) for event Ev (x)

Set Ev increments the event number this will cycle round from 1 -> 7 -> 1

Once a programmed event has been set it can only be reprogrammed, it can only be returned to a no program exists state (7?) by resetting the controller. To make the controller ignore an event the ON and OFF times just need to be made equal.

Adjustment of the clock for BST will need to be accomplished manually.
