In my flat there are two time controllers, one for allowing a specified time
the front passage door is open to allow postman to deliver post
This is a normal controller with a 24hour clock and is easy to set up.
The second controller has a face which has 12 sectors of 2 hours each and I
have no idea how to set this up. This controller operates the common stair
lighting and should operate in times of darkness. There is also a switch on
the face with 3 positions. Up for on all the time, down for operating
according to the time settings and in the middle for what purpose?
I did notice that when in the middle position all the lights were on apart
from two and when the switch was operated in the up position two additional
lights came on.
Can anyone sort out this mystery
Seems like the Smiths rotary timer or a Japanese alternative.
The 3 position switch switch is normally UP on constant.
DOWN on timed.
to set the timer look for little sections around the edges of the face,these
push in (or pull out) to set the on time.
Another type uses little steel pins that push into holes around the face.
You say that in the mid position all but 2 lights are lit ,this may be that
the lit lights are actually not controlled by the timer but operate from a
switch (2way or 2 way and intermediates) allowing tennants to turn the
lights on at night ,these sometimes have delay switches to turn off the
lights after a few minutes.
This would then leave the property in total darkness hence the 2 lights
controlled by the timeswitch.
IME this is common in apartment blocks flats etc to save money on undue
lighting and whilst some on group may argue that energy saving lamps can
save as much or starting flouresent lamps costs more than running for
numerous hours it comes down to the old adage "thats the way its always been
And all the best to all on group for a Happy & Prosperouse New Year.
Thanks I think you have solved the problem with your clear explanation.
There are little sections round the edges which can be pushed up to set the
The problem is instead of a 24 hour straight clock this has 12 segments each
showing two hours so if I wanted it to operate at 7am where is 7am on this
I intend to take a photo of this and let you see.
I have attached photos of the clock- Not very good I'm afraid but it does
show each segment divided into 6,12 and 18 with different symbols. The
clearest one is Me, We, Mi
I did a check and the switch on the timer does control only the two lights.
The remaining lights are either on or off ,operated by using the RCD switch
in the fuse box which appears rather strange.I would have expected a normal
switch to do this. There is a switch below the timer which appears to do
Can you explain this odd marking and how I use it?
From your picture looks like a 7day timer not a daily 24hr timer .
This furthers the reason of only 2 lights probably to act a deterrent rather
It seems the rest of the lights may be controlled elsewhere.
Try looking outside for a photocell.
These vary but common ones are dome shaped and can be wall mounted or on a
This would facilitate dusk to dawn lighting and if faulty could account for
the lights being lit all the time.
Rewiring is an option but further investigation may prove this is not
needed,it goes without saying electricity is dangerous so please turn off
the breaker before trying to trace wiring and make sure the lights ARE off.
As a last option find the feed from the mains consumer unit and fit a 24hr
time switch close to the mains in the feed to the lights.
I can't understand the reason for controlling two lights presumably to come
on in hours of darkness and leave the others on all the time
It would make more sense to control the other lights and only leave the two
lights on all the time as a minimum of light.
