We'd found a pretty clever way to reduce the amount of heating oil that we use. Several weeks ago, we installed programmable thermostats for our upstairs and downstairs zones. These gadgets have settings that let you warm the house in the morning, let it cool while you're away at work, warm it up again in the late afternoon, and then cool down for the night. Some of the more expensive ones even give you the option to have different settings for different days of the week.
The installation process is easy. You remove the old thermostat and, taking care not to break the bulb full of mercury, set it aside.
The old one fits in the old spot, if you don't mind the fact that the old thermostat had a large, decorative plate around it and this new unit is small and rectangular. We left part of the old plate in place to cover the circle where the wallpaper wasn't. (One of us is good at patching wallpaper while the other of us is pretty good at making toast.)
If you carefully follow the wiring instructions, you won't know what you're doing.

We did and we didn't. As a result, with the thermostats carefully installed, we got no heat to those two zones of our house. We've been heating the whole house with the wood stove, almost if we'd planned it that way.
It took us a while to notice; the recent warm weather didn't require much heating in the house. After a couple mornings with the outside temperature in the 20s, though, it was time to get out my trusty
d|i|g|i|t|a|l screwdriver and fix these things.
Yes, I turned the power off before working on the wiring.
Who'd've thunk that the white wire goes into the connector that has the red jumper on it, while the red wire goes on the other side?
Yes, I (finally remembered to) turn the power back on after I'd changed the wiring.
So, now we have heat throughout the house.
Next stop? Maybe an outdoor wood furnace?
