Back to the theme of this section.
I installed Evohome late November 2014 initially just installing 12 HR92s and using the control panel to operate them until the relays were installed professionally for hot water and heating. As I learned later what I was doing at first was all wrong because the control panel was the controller of temperature and not each valve.
I used a Honeywell nominated installer to wire in the relays. He had installed Evohome heating before but not heating and hot water. He left it to me to do the binding as had no experience of that. Initially hot water would not heat up. My installer came back and was puzzled as the wiring was correct. He phoned Honeywell who within seconds knew the answer. The sequence of binding was wrong. It should be temperature sensor, hot water relay then heating relay and in that order. Yes if you follow the configuration template and or follow the order of things in the manual but it does not make it clear its a must. A line to say "If you do not bind in this order the system will not work properly" would have been invaluable.
Much was learned from this forum, and still is, and eventually the proper sequence of setting up was followed as advised in these pages (again put far better than the manual does for any newcomers). Being patient and letting it settle down is worth an awful lot. Keep fiddling and the system never gets a chance to learn. Another lesson from these pages.
I hit problems with internet access at the beginning as it would not work in roaming mode. Honeywell online support was next to useless with advice suggesting I had the wrong app on one occasion. Eventually it suddenly came alive and I do not know why.
All worked until earlier this year until right at the time that Honeywell had issues with their server when again I lost roaming access but this time I could receive data in the app but could not submit changes if roaming. Issue eventually resolved with Honeywell's assistance resulting in deleting the old account and starting afresh. I still do not know what really caused it. I suspect now it may have been something my end with the router but the problem has not returned. It works now albeit in roaming mode it can be slow even with a good signal.
By then, also from these pages, I had learned it is worth while using all six set points in a schedule even if some are the same so that if anybody does an override and forgets it will only run to the next set point.
Following that being put right, and following advices here I did a factory reset of everything batteries out etc. and then gradually bound in sequence ensuring that the HR92s were the sensor. That is many weeks ago and other to increase a temperatue when needed I have not fiddled. The system, left to itself settles down well and gives a far better balanced comfort.
Also learned is that too much obsession watching the temperatures indicated leads to frustration that things are not working when they are. For example, a room set to 20 gradually comes up to that and the HR92 will eventually for a time read more, it could go up to 21.5 but mostly if I look at a separate thermostat (the new Honeywell round for example) or a room thermometer they are reading the right temperature for the comfort desired even though it may be different from the HR92. The reason I have just learned is the HR92 is apparently designed to see the temperature at its level whereas the Honeywell Round is looking at a waist height temperature.
In maintaining temperature the boiler is told to come on and off very frequently (set cycles in the settings don't seem to do anything to change this) but once a balance is achieved it settles down. However, opening a door or window can upset this balance until you have given it time to settle down again.
Overall I am a very satisfied customer, Honeywell's normal support desk not wonderful but Honeywell people in this forum invaluable. For new comers do make sure you understand the sequence of setting up, which as said ought to be clearer, look at advices in these pages on the best way to do things but above all be patient, let it develop or learn and stop fiddling despite the urge to do so. Overall, if a user has not had a system like this before, you will appreciate the tremendous difference in comfort level and balanced heat around your home. Also, the ability to turn up the heat in advance of getting home on a cold night as you leave a restaurant!
Plus, like Mavis, if you are away from home and note on your iPad husband has upped the temperature and forgotten to put it back again you can discreetly turn it off remotely even if hundreds of miles away!
I have found optimisation does not seem to work as well as you would expect. By now, in my home, it should know it only takes 30 to 35 minutes or so to get up to temperature but will usually switch on 55 or 60 minutes beforehand. Also it switches off too early such that a room has cooled more than you would want before the set time.
The system is good. A newcomer will read of frustrations on the part of some. With many the problems seem to be resolved and it does point to user or installation errors as opposed to equipment failures. I suspect some properties by their nature of construction will exhibit different times to warm up or cool down, radiator sizes may be too small or too large for a room or property and I imagine this will give some headaches. Optimisation could be more finely tuned than it is, the manual needs improving particularly for those not technically minded, I think the system is prone to cut in and out more often than is necessary to maintain a heat level.
Overall the future is bright, it's not "Orange" it's "Evohome"!
