Have Drayton, the heating control and valve people, gone out of business?

Lots of take overs... but I find lots of links when plugging "+drayton

Have a look at Invensys

My Tempus 1 is the "old" style, about 12 - 14 years old. Since I sent that first post this morning I, too, have found Invensys and downloaded the Tempus 1 pdf. However, this relates only to the latest model which is different from mine.

My problem is setting the on/off times. I cannot set any preferred combination of the two on/off times that the programmer will accept. Either the ON1 and OFF2 flash alternately, or I just cannot step the OFF2 time past 10:00 pm (I push the button, the time flashes, but doesn't increment). I seem to recall that it was a PITA to set the times anyway, which is why I haven't adjusted them for years. Then, yesterday morning, I thought I'd change the early morning setting to come on later and go off earlier, as it is so much warmer these days, and since then the only combination I have been able to set that is, kind of, acceptable to me (and what the programmer will accept) is ON1

But it would be really nice to be able to read that ruddy instruction booklet which I've lost! I suspect that the programmer may be broken, but how does a solid-state device get broken?!!

Does anyone have a Tempus 1 booklet for the model of roughly anno

Do bear in mind that the current Tempus 1 is a completely different animal to the earlier model, which is probably the one you have - the newer model is white rather than brown/mushroom. I had the earlier model Tempus 7, and when it packed up I fitted the later model. I liked it so much, I installed one when we moved house a couple of years ago. Maybe you should treat yourself!

The 1 sort of indicates this is a single channel device for the heating only? If it's a two channel jobbie, ie does both HW and CH is it in "gravity" mode and therefore won't let you set CH times that are outside the HW times. Just a thought, I've been caught by that before now.

Well it's a micro controller maybe it's "confused" rather than "broken". Is there a "reset" to factory defaults hole anywhere. Or you could try removing all power to it for a few minutes. Has it battery backup, though that might just keep the clock running.

Yes, it's for heating only. This is a Servowarm-installed system, with a mechanical valve in the airing cupboard to switch between hot water and heating or a partial setting at any stage between. I think you could be right that the programmer is stopping me from setting the OFF2 time for a reason (rather than being broken), because I can remember reading somewhere that it wouldn't allow a time before midnight (i.e. yesterday) to be set.

However, the kind folks at Invensys are in the process of sending me a printout of the instruction manual! I am getting a very good response from their custmer service.

It does have a battery, although this is a really strange thing: the product is at least 12 years old and I have never replaced the battery! In fact, the battery must be buried deep inside it somewhere, because there is no access flap to it from the outside. I assume it's the kind of battery that is fitted to PCs to have them maintain their date/timestamp for years. If I unplug the programmer (It's fed from a

In any case, I now realise that if it is broken, a new replacement is only about 30 quid, so it's not quite the horror story I initially envisaged.

Thanks for the feedback.
