Is there a programmable thermostat that can be set to turn the fan
on/off at set times?

Our furnace fan only comes on during the cycle unless we switch on the
fan manually. In the case of the latter, we get the high speed, which
is okay, but sometimes we forget to turn it off for the day and this
chews up lots of $$$ needlessly.

In the morning, we use the manual fan to push more cold air upstairs as
well as to generate some ambient noise so as to not wake the kids up.
It would be great if we could just have it come on automatically at, say
5:30, and switch off at 7:30.

I see the 8000 (others?) has this feature, which randomly turns on the
fan for a 35% duty cycle. This doesn't do exactly what I wanted, but
it's still worth a closer look. Thanks.

frankly its a major pain in the ass to program

I believe its designed for a certain generation, certainly not the
older folks.

Every thermostat manufacturer I know of offers several models with
programmable fan control.

Damn, I think it's loaded with features and pretty simple to program and
operate.

Have you ever played with the W/R's "Blue" version?
Talk about a POS that is hard for the installer and the end user!
