My Alpha Boiler thermostatic controller isn't doing what it should be doing ...

[tellmewhenthespaceshiplandscoz]

Morning MN, wonder if anyone can help ...

So we've a combo boiler (housed in airing cupboard upstairs) and a wall mounted thermostatic controller downstairs which "talks" to it according to settings.

In terms of heating settings you can either do clusters and of days (Mon-Fri) and (Sat-Sun). Or do individual times for individual days. I prefer the latter as our schedule is different throughout the week.

Yesterday we had the display notification to change batteries. So did that.

We always use the individual day settings and that’s worked fine although I think historically the cluster settings are in the background. I have a vague memory that this has once in the past interfered (cannot for life of me remember what the solution was that engineer gave for his 15 minutes and £65 fee 😳). annoyingly, you can’t turn one type of setting off completely although you can change the times within the cluster setting to the same I.e Come on at 6am and off at 6am so in effect it doesn’t come on.

I hope I’m making sense so far.

So this am I woke at 7am boiling hot as the heating had come on. Weird as Sundays setting was 8am.

I’ve been trying to work out what’s up with it so I can continue to use the individual settings however -

1.	With the cluster settings set as I’ve described above (so they don’t kick in at all) this seems to override my day settings so the heatings not coming on at all. 
2.	If I put the cluster settings on to come on at the same time as Sundays settings but turn off half an hour before the Sunday setting it ignores Sunday and listens to the cluster.

Heating works fine if I manually turn I on and off.

So - in summary, I can either leave it to just do cluster settings but it gives us no flexibility to tweak each day, or

I just manually turn on and off. Which means if we’re out we can’t have the house warmed up before getting back or have to leave it on when out which is a pain.

So a total first world problem as we do have heating but it’s annoying me that I can’t use it as I have been.

I can’t find any specific advice online other than what’s in the user manual which has no help at all.

For some reason the reset button is dong nothing either.

Any advice?

Forgot a pic

Assuming you haven't got the instruction manual to help you, there are lots of You Tube videos and the instruction manual for Alpha Central heating controls available online.

I'm sorry but all I could pick out in your post as relevant is this part:

Have you checked your BST settings?

I have the user manual which has no trouble shooting section and online versions are PDFs of this

I've tried googling the make and model and a few words to describe issue but nothing helpful returns

Yes! That did occur to me and clock times are all as they should be!

Was it changing the batteries that seemed to trigger it? I just know that when the batteries go in my Mum's thermostat, the system does all sorts of strange and unexpected things. Last time the temperature setting was all over the place with the radiators getting hotter than they should.

It might just be worth changing the batteries again and ensuring that you are using brand new batteries out of a new pack. Some electronic items can be very fussy about batteries. My wired in smoke alarm back up battery system doesn't recognise anything but crisp new Duracell!

It's a quick thing to try just in case.

Oooh so I've just spotted (see first two pics) that it's showing day of the week as 6 when it's day 7. I did set yesterday's heating to come in earlier so wondering if that's the problem. I'll feel like a right knob if it is

So set to day 7 and timer should kick in later this afternoon so I'll wait and see (DH has insisted I patiently wait as apparently my constant messing with it this am may be messing things up more. Can't help it - if a problems needs sorting I have to attend to immediately!).

@ForPearlViper that's a good call actually and I've had that with other appliances in past.

If issue persists I'll get some decent ones not £land spesh.

You tube has lots of great tutorial videos regarding household appliances.

Yup and I've tried finding one for this make and model for this very specific issue.

If it's just got itself in a mess I agree with taking out the batteries again, leaving it for a few minutes to make sure it's fully de-powered and then restarting it. Is there an on/off switch you can turn off before removing the batteries so it hopefully turns on dead and doesn't get a power glitch as the batteries go in?

Also good suggestion ... I'll wait and see at the next program time (2.30pm) what it does.

If no joy I'll turn off before taking batteries out (we didn't do this yesterday) wait 5 then pop back on time on and see.

Hoping changing day number will have fixed it.

Thanks all!

Mine loses time and was 18 hours out so heating started coming on at 3 AM! Re-set the date and time and all is well.

Sorted it! Think something has messed the date up so I changed that and it came on at 2.30 as programmed.

Thanks for replies folks

That's a great update! My next suggestion was to get a big hammer... 😂

.... I would have been open to that suggestion early this am
