Are there any thermostats (any type) that are smart enough not to
turn on the heat at 10:55 when they are programmed to set back at
11:00? It seems wasteful and hard on the equipment to do so.

So make your setback 10:55. No wait then it might come on at 10:50.

So if it wants to come on at 10:50, let it but don't shut it down
until 11:00. If it wants heat at 10:55, don't bother.

Or if the thermostat demands heat at 10:59:59, turn the heat on,
but run it for X minutes even if the setback occurs.

If the point is to prevent short-cycles, either of the above would
do it. If the point is to save energy, set it back at noon. ;-)

Even if the furnace is running almost continuously, this in
only going to save you 1 extra start/stop cycle a day,
during the heating season. What's the point of even
worrying about it?
