I was hosed! Do not trust BuyPlumbing I need this right away and I was told twice it was in stock. I paid extra to second day ship it then I get an e-mail saying it's on back order for at least two weeks. They did NOTHING to try and solve the problem.

This excellent thermostat is exactly as advertised and much easier to install and operate than other reviews would have you believe.
1 Amazing Thermostat December 14, 2009
David Benevy (Pennsylvania)
I've installed over a dozen of these in various applications and I am very very happy with them. The 7 day programming feature is very easy to use, I don't have to keep a manual handy and follow it step by step as is the case with many other units. One of the best aspects of programming to 722e is the COPY button. Once I have settings for four time points for one day I can copy them to any other day, MON-FRI, SAT-SUN or ALL DAYS. Even if you aren't running the most complex devices, i.e. multi stage heat pumps, it's still a good choice. I have some controlling a single zone of heat.
To control elecric baseboard heat I use a DPST Contactor relay with a 24VAC coil powered by a 24VAC transformer. One transformer can control several relays. By doing so, and placing the thermostat away from the heater you can obtain very good control of your temperature.
In applications where I am paying for the heat, but someone else is using it, the LOCK feature beats one of those boxes that locks the thermostat up. I can disallow the tenant to alter the settings by locking the thermostat with a code of my own choosing. In one application, since I don't know the hours the tenant will be using the heater, the 722e allowed me to program a maximum temperature, allowing the tenant to set any tempearture they want, so long as it is 70 degrees or less.
The 722e lets you program the "swing", the range that controls on and off. I used this to control a steam oil system which serves as a worst case backup for an electric system. The steam system takes over 30 minutes to produce heat and I only want to use it when the electric system can't keep up. So whereas my main heat is set for 69 degrees with a .25 degree swing I programmed the oil thermostat at 66 with a 2 degrees swing. This way it will not come unless the temperature falls below 64 degrees, and it will stay on until it has reached 68 degrees.
The final icing on the cake, for those trying to understand energy use are the energy used readings. These give you the heating and cooling hours of operation, today, yesterday and cummulatively since you last reset the counter. With them I can see how long each heating or cooling unit is running on a daily basis, which gives me feedback to see if I should alter my programming. All in all this is a fine thermostat that is easy to use and can save you a lot of money if you use it right.
Good Thermostat -- Takes Some Programming and Skill October 21, 2009

Good thermostat, once I got it programmed.
I'm good with electronics .. I would not recommend this thermostat for someone who is not familiar with heating and cooling system, how they work, and what makes them tick...!!!!
I had no problem with getting it programmed, however, and it works great.
The best feature I like is the ability to program the fan to run for certain periods, regardless of whether the thermostat is calling for heat or cooling... We set the fan to run in the morning during our morning shower time, so that we can move the moisture throughout of home, and not have it trapped in the bathrooms only during shower time....the fan runs, regardless of whether the thermostat is calling for heating or cooling, or no haeating or cooling at all. A great feature...
A great thermostat for those who understand heating/cooling system terminology and theory of operation...

This is NOT the programmable thermostat you're used to. If you have a good idea of how your system works, this stat will do anything --- anything --- you might require. The BEST feature (to me) is the separately-controllable blower feature. Instead of waiting for heating/cooling demand, this unit can be programmed to trigger the blower unit for varying amounts of time through program periods that do NOT have to be the same as the demand periods.
Sound complicated? It really isn't. If you have forced-air, it's nice to have the air moved around periodically, even if you don't need heating or AC. This assists in keeping the temperature even throughout the living spaces --- as well as improving filtration, a really important feature.
This fan feature really shines in the summer, since air movement makes a slightly higher temperature more comfortable --- so the AC can be kept a couple of degrees higher. We have another "bonus" --- a very large, very cool finished basement. The blower cycling periodically helps to "scavenge" cool air from the lower region and move it through the house. The result is that the AC unit cycles far less, especially at night. (This is the main reason I purchased this thermostat.)
Heating/cooling controls are precise and are fully-controllable, with quite a few available settings that you might want to read a bit about first. (The potentially critical settings are well-buried in the menu, and there is a lock-out feature that can be handy with inquisitive kids.)
