Easiest change over, get much better and consistent heat and cool. Simple changeover from present. Old mercury round one. Keeps a closer ratio for heat.

These thermostats are replacing my old Honeywell round ones, so far see a big distance. Just got a new oil delivery will see if it helps in burning less. Hope so

As always, there is no other product that is of higher quality design or function !, the same goes for all these Honeywell products. This thermostat is just what I was looking for, it maintains the setpoint as perfect as can be and the backlight is a huge plus. I could go on and on.
