So different from the Red Dot which shows that its within a HW schedule but not necessarily heating.

As others, I am also seeing the same this evening with warm weather saver enabled in that certain zones are greyed out and showing the Off icon and certain zones are showing normal working. All zones are set to use warm saver. However, I do appear to see some impact from Advanced Load Scaling being set on. Whilst a couple of the zones were showing as below temp and active, the boiler didn't fire. I left it for approx. 10 mins and still no boiler activity. One zone was 2 degrees below its set point. After playing around with Warm Weather Saver and not seeing an impact, I tried turning off Advanced Load Scaling and the boiler fired. I then tried turning Advanced Load Scaling back on (both full and partial tested) and the boiler turned off.
So two questions
1) When all zones are set to use Warm Weather Saver, what determines whether a zone shows as being "off - ie greyed out" and what determines that a zone should show as "normal" ie being active even if the zone is up to temp
2) Why does Load Scaling stop the boiler firing when some zones are in Weather Saver Mode?

It seems there are a number of us with “old Glow Worm boilers”. It says a lot for their long life qualities. Unlike today’s versions


I still await my beta update so am intrigued to see what it looks like.

We have an Ideal Mexico S2 that was probably 4 or 5 years old when we moved in in late 1997 - which makes it at least 25 years old and (fingers crossed) still going strong. Have been advised not to change it as there’s very little to go wrong.

I have to confess that it rarely gets a service.

Update - Conservatory zone showing as "off" dropped 0.5C below set point still showed as "off". then dropped 1C below set point and zone was automatically reactivated- rads are warming up

I am envious. I can’t wait to be able to play!

todays update - a mixed bag on the controller with some zones showing warm weather saver on (the zone greyed out and showing the off icon), other zones working as normal. A very interesting situation though is that I have two rooms adjacent where room one is on the outside of the house and due to its construction does loose heat quickly as large glass areas and quite old garden room type design, the adjacent room is protected by other rooms. Normally they behave to a degree the same so the outside room is quite cold and needs extra heat. This morning the outside room rads were full on and the inside room rad was off even though both have the same temp setting and were up to temp. Rather clever as the system had detected the different behaviour of the rooms and proactively compensated rather than the usual reactive response from evohome. Hoping this is a feature of the updates and not just a freak behaviour??

yep some very interesting and leading edge features in this update Hope you get your update soon

So, that's now both Saturday and Sunday on my controller setting my bedrooms to 35C. Today, Monday, it all seemed ok, but, I may simply not have been up in time to see it early on.

@AlexP and @roydonaldson.
I have had a conversation with the Elves and this is a known bug.
It looks worse than it actually is, the rooms will not overheat because it is reporting 35°C the target temperature is still the real setpoint.

Thanks. Good to know. Whew.
