It's blowing and snowing like crazy here in Michigan!
Got home from dinner, and I found the house at 66 with thermostat set
at 71. Furnace would not light, but I suspected the combustion air
was restricted, which was the case (inlet capped w/ snow). Fifteen
minutes later, we had heat.
My wife said she was glad I discovered this at 9PM instead of 1AM ...
me too, then it hit me.
If the thermostat is set at 71, and the temperature is always
maintained between, say, 69 and 71, then anytime the house temperature
falls to 68 (let alone 66), it would be abnormal. Is there such thing
as a thermostat with a low (or high) temperature alarm that is some
offset from the setpoint (e.g. +/- 3 degress)?
Yes it's called an alarm company. They install their own stat and monitor
your house for you when your gone away, vacation ect...
Why would you need an alarm in your thermostat? Isn't it fairly obvious when
there is no heat?

Intake was turned down with 90 and bird screen (which capped over with
snow). Exhaust was straight out.
In short, no, it is not obvious. If there is no heat at bedtime when
it is 0 outside (which was nearly the situation when I posted), the
house will get cold quick before it wakes anyone. I'd prefer to have
as much notice as possible.
Good thought ... thanks for sharing.
Not a bad idea. I have not seen one but it should be a fairly simple
enhancement to any digital thermostat. A little piezo buzzer that
beeps when the unit is on but the air temp has deviated from the
setting by more than x degrees. It would alert you that the unit was
not working properly. Suggest it to some thermostat manufacturers.
