Tools and Hardware Reviews of Honeywell TH5110D1006 FocusPro 5000 Non Prog ThermostatCustomer Review: Outstanding Thermostat Summary: 5 Stars
I installed a programmable Honeywell RTH7600D thermostat in the home of my parents (who are in their late 70s) to replace an old mercury switch thermostat. It worked great, but then I started to worry about what would happen if the programming got screwed up by accident. It seemed unlikely that my parents would be able to wade through the instruction booklet, and the thermostat wasn't intuitive enough for me to talk them through it on the phone. And besides, my parents had been in the habit of adjusting the thermostat at wake-up time and at bed time for most of their lives, so the programming feature was kind of overkill for them.
As a replacement, I picked the Honeywell FocusPro 5000, and everybody has been thrilled with it. It has only 4 buttons whose functions are completely obvious (temp up, temp down, fan auto/on, and heat/cool/off. The only time you need the instructions is during initial set-up so the thermostat knows what kind of system it's controlling, but once that's over with, the instructions can go in the drawer.
This thermostat does NOT require batteries, unless it's hooked to a system that lacks a "common" or "C" wire. Most systems installed in the past 20 years have a 24 volt common wire terminal on them, in which case batteries aren't required as the thermostat takes power from the HVAC system itself. It's possible that some systems that have a 24 volt common capability didn't have it hooked up because many older thermostats didn't need 24 volt power, but if that's the case, it's pretty easy to make the connection at the furnace or air handler (turn off the power first!) and then make the connection at the other end on the thermostat using one of what are probably several wires tucked back into the wall behind the old thermostat.
The FocusPro 5000 has a huge display that even the most visually impaired person can read easily, day or night. The back light is strong and comes on for about 8 seconds once you press the temp up or temp down button. Digits and letters are dark and bold. Temperature control is precise. Yes, there is a soft click when the relays turn the fan or compressor on, but it's only minimally annoying, and I don't know how it might be avoided (unless you go back to a thermostat with a mercury switch).
My only word of caution: if you have a heat pump system that includes auxiliary or emergency heat (i.e. an electric heating coil in the air handler) then you'll need to order a FocusPro 5000 model that can handle TWO heating zones (such as the FocusPro 5000 TH5220D1029), as auxiliary or emergency heat is considered a discrete zone that a 1 heat/1 cool thermostat won't be able to manage.
