We have a Busch-Wächter '250 Master' light sensor at the back of our
(UK house, but no operating instructions. I think the sensor is
triggered by night-fall, when it switches on three exterior lights
around the front, side and back of our house. It is labelled Art. Nr.
6874.

There are two visible controls. One control has a sun and a moon
symbol at either end of the scale; the other control has 'Min - 1 - 5
- 10 - 16' marked on the scale; there is a symbol next to this second
control that may indicate 'elapsed time'.

The controls are currently set to 'moon' on the first control and to
'min' on the second control. I have no idea what these controls are
for.

The lights come on when it gets dark, but they stay on until well
after dawn; I'd really like them to switch off as soon as it starts
getting light. I'd also like to know if there is a way of disabling
the sensor altogether, so that it doesn't switch the lights on at all.

All ideas (and/or instructions) gratefully received! Thanks, Steve

The usual controls are ambient light (to stop it coming on in the day),
sensitivity (so cats don't set it off) and time. HTH.

I'd guess the one with the moon and sun sets the sensitivity at which it
triggers - moon darker, sun lighter.
The 1-16 the time it stays on after triggering.

To disable it you'll need a switch - probably easiest on the feed to it.
