FAQ & troubleshooting
Why does the light switch timer not turn lights on and off? (‘n’
shaped inserts required)
The gap between the switch and the control wheels is too
large. In order to reduce this gap please use the clear ‘n
shaped’ inserts. This will allow the wheels to contact & roll
over the complete face of your switch.

Remove the cradle by loosening the screws on the switch by a
few turns
• Insert the “n” shaped insert into
the recess of the cradle as shown.
• Re install the cradle.
• Re-tighten the screws and insert
the unit
Note the Inserts sit between the wall and the switch plate –
moving the switch forwards allowing the wheel to make
contact.
Why does the light switch timer do the opposite desired action
(turns lights on when they should be off and off when they
should go on)?
To turn lights on a switch is pressed ‘down’
To turn lights off a switch is pressed ‘up’
If this is not the case on your current set up, then your switch

plate may have been installed upside down. You will need to
rotate your switch 180 degrees. Upon doing so your light
switch timer will function as intended.
How do I reset the timer?
To reset the timer and erase all pre-set programmes, use a
pointed object, such as a straightened paper clip, to gently
press the rest button. The display clears. The LCD will show AM
12:00, MON (Monday), OFF and current room temperature.
NOTE: After resetting you will need to reset the current time
and day.
Why is the light switch timer showing an Error message?
When "Err" (error) displays on the LCD,
Check and remove any obstacles that may be stopping the
back plate from moving.
Remove the batteries from the unit
Wait one minute before reinserting the batteries.
The clock should now show 12:00 and the timer should now
operate as expected. In the unlikely event that you the Error
message reappears your unit may have developed a fault and
will need to be returned to the retailer.

Will the light switch timer work on a 2 way circuit switch plate?
When using the timer on a 2 way circuit it is important to note
the on /off position of the switch will change and as a result
the unit may not operate as expected.
Ensure the switches are in the correct orientation when using
on a two way switch.
