Watch out for “Smart Response Setting” I had to replace an older cheaper Honeywell that decided it didn’t know what time of day it was.I decided to go with this more expensive model– but I had reservations after having read some reviews and comments elsewhere where some people complained that the furnace was always on, or they were burning more oil or gas than before. . .I found the reason–It’s called ‘Smart Response Technology’It’s ‘ON’ by default if you do the quick DIY install.To turn it ‘OFF’ you have to download the FULL MANUAL from the Honeywell site to see how to get into the ADVANCED Settings of the device. The pamphlet you get in the package is just your BASIC setup.I bought the programmable Honeywell to control my oil usage and keep the furnace from heating the house in the dead of the night when everyone is in bed. And I would set the Program to turn the Furnace ON and reset the Temp back to 70 degrees at 7 AM. In short– The Furnace turns…

I chose Honeywell as they have always gave great life and service. I am using this on a steam heat system only, so I needed to connect only two wires. I did leave the jumper in as directed in the manual. I did power off my heating equipment (very important) we don’t want surprises. This thermostat has a large display which can be back-lit simply by quickly pressing one of the control buttons. I only needed to program morning and night settings, you simply skip over the times you don’t want to program. When in operation it displays both set temperature and room temperature. I would have to say it is accurate within +/- 1 degree as I compared it with three other thermometers. I installed the batteries before I attached it to the wall base and did all setting and programming ahead of time. The batteries are easy to replace when needed as they fit in a flip out holder from…
