timer switch

[Johnjo]

Is it possible to get a 12 volt timer switch?
Bought a coolbox back in the summer works o.k,
Problem is overnight, bring the tempature right down late evening,
In the morning it's crept right up again,
Need something to switch it on and off at night.
Batteries are not a problem,have plenty of amps to spare.

If amps ain't a problem why not leave it switched on and let the thermostat turn it on and off?

Answer to that is,
It does not have one fitted.

Yes; that seems to be a pretty good reason.

Eberspacher now use a programmer on their heating systems just like the ones we use at home. They must run on 12 volts so perhaps that's your answer? Try Krueger on 01425 619869 they are very knowledgeable and helpful and they can spell.

It won't be cheap but ask.

Thanks for that will give them a call.

There is also Farnell and another that escapes me at the moment to look at.

Re: Could that be...

That was another I forgot about. I have ordered from them in the past.
The other one I was thinking about was Maplin.
Thanks Steve.

An old idea but works ....

Many moons ago the Convoys had what was called the Convoy Clock......

It was a standard Ships Bridge clock all brass etc. Around the face was a metal ring insulated from the clock face. On this ring were adjustable pointers that pointed just a little into the face of the clock. The minute hand had a piece if wire extended of its end that bruyshed against the pointers ... causing a bell to ring ... indicating time to zig-zag or whatever.

Now taking this idea a step further ..... an old wind up or quartz clock, with the HOUR hand suitably amended with said wire, a set of pointers around the outside face .... and bingo - a DIY timer. It does not have to be wired direct to the cool-box ... a relay can do that, click on - click off.

OK OK ignore me - It was only a thought !!!!

Eberspacher timer switch

The one you want is part number 5010002. Red positive, brown negative, yellow switched output. This part number has an internal battery that saves your programming settings. The other one, 5010001, needs a separate supply to power the memory.

As someone else suggested, this is not a cheap option. From memory mine cost a good deal more than 50 pounds!

Nigel
had same idea myself,
But could not think of a way to stop it all welding itself together,
Good idea with the relay, Got to be honest did not even enter my head,
So simple,yet so far away.
