Intelligent-recovery doesn't save any energy; it's just a marketing feature. Even the savings from non-intelligent setback is debatable. "Up to 1% per degree of setback", yeah right, the magic word is the "up to".

programmable therostats

Anyone know about the Honeywell programmable thermostat with the smart reponse technology. Its supposed to take into consideration the air temp, wall temp, and the time of day that you want the room to be a certain temp. Supposed to be a energy saving feature. is this true ,or is this a bunch of B.S. Thanks.

It's called \"adaptive intelligent recovery\"...

and it's a standard feature on our TH8300,TH8100, and TH6110 series VisonPro programmable stats. It's been used since the Chronotherm 3 in the 1980's. It "remembers" what the temperature was for the past 3 days, and starts the recovery based on having the space at the comfort setpoint at the time the period begins, not just turning the system on like the old mechanical clock units did. In other words, it "ramps up" the temperature gradually so that you are comfortable when you get out of bed or come home. Only the stats I mentioned have this feature. The TH4110 and all the non-programmbles do not have it.

On an extremely cold night, you may notice the system coming on earlier than normal, but that is the Adaptive Intelligent Recovery ramping up the temp. For more info go to www.customer.honeywell.com. These stats are available from your professional heating & cooling contractor. By the way, the wiring hole should be sealed so that the stat will not be influenced by the wall cavity temperature.

Since the VISIONPro 8000 came out 2 years ago, we've installed nothing but. We love them and so do our clients! Easy to program, good looking, and great energy savings!

The intelligent response feature works quite well.

How much setback to use is much more complicated. It depends on the structure, its' construction, its' insulation, its' infiltration, outdoor and indoor temps, etc.

In general you want your boiler or furnace to kick on at least once during the setback periods. If it only kicks on to "recover" use less setback. If it's kicking on numerous times you can use more as comfort dictates.

The are almost perfect

but need to be able to control heat pump and 2 stage backup to be perfect!

The TH8320 Vision Pro..

is good for up to 3 stages of heat, 2 stages of cool on a heat pump. The TH8110 is good for 1 stage heat/ 1 stage cool on a heatpump, both are also compatible with steam, hydronic and scorched air.

3 stages

from what I see and was told by the support people, the 3 stages mean 2 stages of compressor plus backup. I want 1 stage compressor and 2 stages of backup. I can do it with a Totaltouch sold by Bryant & Carrier suppliers but don't see how it can be done with the 8320.

Last year I picked 2 of there CT3451 models to replace the old sun dial type I had. They work great, easy to use and install. They ran about $45 each and after programming them I saw a nice decrease in my oil bill. These things pay for themselves.

John, you are right.

It can't do that.
