Timer For Lighting Circuit

[jumpin jax]

Ask the customer wether they want a digital or analogue timer, fitted a digital timer (£15) last month and the old codger said he couldnt work it so his son paid £80 for an analogue. If you do fit an analogue one make sure it has a battery back up in case of power cuts. The analogue ones take up 2 ways so you will have to fit an enclosure

Reel 'em in

yup! exactly! thats why i was thinking an override switch..

So you would need a programmer with the ability to have different settings for each day and have to remember to leave all the light switches on a minute before the sabbeth day, or alternatively wire a second switch wire to each fitting that would be controlled by the timer unit. I don't see how timing the main feeds would be an effective method as the switches would have to be in the on position and need turning on anyway.

Jumpin jax... the cusomer has asked me to quote on both analogue and digital.

Skykraps... Yes the timer would need to have a 7 day cycle, unless I could attach an override switch that bybasses the timer during the other 6 days Ive already informed my customer that they would have to have all relevant light switches in the on position for this to work, but this can be done before the sabbath starts. Granted not the most efficient way of doing it, but considerably cheaper that running additional switch wires!

contactors would allow you to use timers to switch loads larger than their rated current capacity.[/QUOTE]

Or multiple circuits from the same controller :0

What if they forget to leave the light switches on? Most people have lamps they would be better off with a plug in timer.

I recently saw a system where a central heating timer had been used to control 2 lights (so one was connected to the "heating" output and the other was connected to the "water" output) - and the overide was courtsey of the +1 hour button. The bonus I guess of using such a device is that it would have battery inside so in the event of a power failure the clock wouldn't stop.
