That appears to be a file in a folder on your computer

Fair enough - that's a pretty versatile 'multi-channel' one. However, I still think you might struggle a bit to find a 2-channel one which is not labelled' as CH and HW.

You might but as it's not what you want why would you buy it?

Presumably if/because one couldn't find one labelled according to one's intended use of it - leaving one with the not-too-elegant sticky labels you kindly posted an image of!

And what's wrong with a direct drayton replacement ?

Must be the most common programmer.

or get a 722 if you want to control each day separately.

The thermostat now calls for heat when it drops past the set temperature and switches the boiler on and off as required...However the boiler still fires even when the programmable timer is set to off as I reported before

So the thermostat now works, but even when the heating is turned off on the programmer as if the programmer was turned on?

Am I correct??

Remember if you get a new programmer to get a 2 channel one.

Yes it would seem that the new thermostat is now doing its job correctly but even when the programmable timer is set to off the boiler is firing...Looks like a new programmer is my next purchase

Although having said that, you don't really need a timer for CH with modern programmable thermostats.

does it not have times and temperature set points

Never thought of that, I just went for a basic digital thermostat. In hindsight it may have been wise to invest in a fully programmable one. I have booked a visit from my heating cover provider, hopefully they can resolve the remaining issue for me (with a free programmer )

Surely you would still need a programmer for the W/H function

 

[AndyPRK]

Yes. But the hw channel on the timer is working.

Yes, probably - although I don't think we've been told so. If so, I suppose that a programmable heating stat plus half of a (presumed) half-knackered CH/HW programmer would serve the OP for the time being - but it's hardly a very nice long-term setup!

All sorted now folks. New thermostat is now working fine and a new programmer was fitted today....Just in time for the snow, thanks for all the feedback

 

[AndyPRK]

We haven't been told the hw channel us faulty. And I can't see how it could be broken.

Bypassing the ch channel is fairly typical when fitting programmable stats to avoid the confusion.
