Taking Care of Business: Outsmarted By My T-Stat

I am stupid. I can’t even program a TiVo, so it should come as no surprise that I don’t understand the concept of a programmable thermostat.

I always assumed that when I programmed a temperature into my very nice thermostat, the thermostat would tell my furnace to start up or shut down at that precise temperature and moment.

For example, I set my temperature to 60°F at 9 p.m. and for 65°F at 5:30 a.m. It is cold at night, but that is why God invented blankets and thermal pajamas.

The thermostat clicks at 9 p.m. and shuts down the heat. I go to sleep later, but as I am prone to do, I wake up in the middle of the night. Several times I have felt the heat from the register and checked the thermostat around 3 or 4 a.m. The darn thing is on and the setting is 65°. Huh? I checked my program and it still says 60°. What gives?

It appears everything is set correctly, but the thermostat has a mind of its own.

It does have a mind of its own.

I contacted my contractor and he said a feature known as “intelligent recovery” caused this. This means that the start time in the morning is adjusted so that when my “feet hit the floor” at 5:30 a.m. it will already be 65°.

I was going to pursue a response with, “Why didn’t you tell me…” but then I read the owner’s manual. The light bulb went off over my head - as dim as I, er, it may have been.

aaahhhh how to say this? i must have a smarter thermostat than yours. mine fires up the furnace about 20 mins early. not 2.5 hrs or more early. you might try seting your 65 deg setting 2 or 3 hours later and adjust it until it suits you. you know maybe your thermostat is just plain cold and is pissed so it turns on your heat. that's it, its thermostat abuse.
