WritesQuoted Text HereHoneywell really are the kings in this game in terms of sophisticationand ease of use eg CM907 (wired) CM927 (wireless) but they are priced tomatch and I still have a few niggles with them:1. The relay on the 907 makes a ridiculously loud pinging sound when therelay is energised, not a problem for me as I am using it with a remoteroom sensor but it would be really intrusive in a living room or bedroom(for multizone).2. You can't turn off their proportional control system which (when inproportional temp range) insists in breaking each hour into 3 or 6segments, firing the boiler for a time which it thinks is right duringeach of those periods. Proportional should be more accurate but I'dprefer to have the option for on-off control to limit the cycles on mycontrol valves and repeated boiler starts.3. I've had a couple of 927s lose the wireless tying to their relayunits following power failure requiring re-tying by an obscure and wellhidden service option. Very inconvenient as I had to travel a bit to getto them.Agreed the Danfoss doesn't look that pretty but its proportional mode(they call it chrono-proportional mode) can be switched off.
I see theyalso do a remote sensor version TP7000A but that's a bit more pricey,67quid was the cheapest I could find it with 80quid being the norm.That 5+2 programming option is nice, copying days on the honeywells iseasy but and 5+2 option would be simpler.

The display has a little up or down pointing trianglewhen an overide is in operation. There is the +1 +2 +3 extenstion tothe current set temp as well. I think the TP7000 is the currentversion.Quoted Text HereWhy?
Programmable stats are far nicer as far as comfort is concerned.Programmable stat!= wireless.

On theprogrammers I've had that simply switches the zone on for an hour.That would have the same effect as using the temp up/down buttons,except that lasts until the next set point time.Perhaps your customers have trouble understanding programmable statsbeacuse the explantion being given to them isn't clear or simpleenough?
B-)The biggest difficulty maybe getting over the fact that you no longhave dedicated periods of 'on' or 'off' with a single temperature.The heating is basically always 'on' but if the house is warm enoughit doesn't demand any heat. The temperature is controlled to what is.actually required. for at a particular time.
Quoted Text HereThe trouble is that almost nothing comes with instructions which arecomprehensible to the target audience.A very large proportion of instructions are, of course, written inChinglish, but even if we ignore those ones, most of the remainder arelittle better in the end of the day.The percentage of instruction manuals written from the point of view ofthe typical end user is tiny. Comprehensive concrete examples of howto achieve common desired outcomes are few and far between.Of course, to move a little bit OT, some manufacturers do it to ensurethat the only people who are likely to be able to program theirequipment are those who have been on expensive company-run courses -Panasonic telephone exchanges are a case in point.
