Product Review: Honeywell Home RTH221B1021 RTH221B Programmable Thermostat

 

This is fairly easy to install. The instructions are easy to follow and as long as you are not totally colorblind, you should not have problems with connecting any of the wires. Why I give this such a low rating is that it had to be replaced in less than a year. Basically, it worked fine until it did not, and neither of the others that have been installed since then (the basic digital one that Xcel replaced this one with or the new programmable one I installed to replace that one) has failed so whatever broke in this one was not due to faulty wiring.
