I found that when I changed the number of hours it had to relearn from scratch - ie the next time it switched on it came on at exactly the set time.

Not sure if this is the right page in the forum to mention this but I noticed last night that if you manually change a temperature setting on the HR92 very close to a controlled time schedule change your override seems to go on beyond that until the next time schedule. My bedroom radiator is set to drop temperature at 23:00, at 22:55 I turned up the temperature to give the room a little boost thinking that 5 minutes would do it (often does) and expecting that the 23:00 schedule change would then put it back to the normal overnight temperature. I go to sleep within minutes (often seconds!), woke up at 12:30 a.m. feeling rather warm! Have checked the time setting on the controller and that is correct. Lesson learned!

Must say I have been caught out by that but have never got to the bottom of it. So I added in the second shut down that Richard recommended which is roughly 1 hour after the room set normal set down point and that pretty much guarantees that whatever happens that shutdown point will be applied. Be interesting to know why this situation can occur though?

No, I checked my clock and it is OK. I can only think it is the very close proximity to the set change that caused it to be ignored. It it had a brain probably it would be saying "No idiot would make this change at this time, he must mean it to be operative to the next set change so I'll delay it until then." Except one "idiot" did want to make a change 5 minutes away from a programmed one!
I set up the maximum of 6 changes for each zone generally making them 07:30, 10:30, 13:30, 16:30, 19:30 and 22:30. The daytime temperatures though are all the same, currently set to 18C and I use a custom menu to effect an over ride if I want one in more than one zone. The main bedroom final time of the day is 23:00. Perhaps I better change the bedroom ones so that the final one is say 00:10 in the bedroom. It is the only zone where we way want to override the setting - for a short time!
This highlights another issue. I have set up the customisable menu, called it "Custom 21" as it sets the temperature in designated zones to 21C, but you can only make the change to run for one day or more whole days ahead. Nicer if you could set it for a few hours as well.

Reading through this thread - and others - how does Honeywell expect to educate the masses on the nuances of its smart heating controls? Not everyone has the time or inclination to pour over forums for advice on what should really be a 'set up and forget' system. I just wonder how manufacturers are going to address the steep customer learning curve? I am a retired pilot and when we first started getting flight management systems on our aircraft we used to have a saying on the flight deck 'what on earth is the computer up to now?'. I am feeling a touch of déjà vous coming on.

Give it a week or 2...You'll notice the start time gradually being delayed...Assoc IHVE; Matthew Hall Satchwell MW Kellogg CompAir; posts are personal and my own view
