Hey all,

My furnace seems to be running all right, but, one thing has me
curious.
I've got a Honeywell stat that is supposed to have "smart recovery"
that learns the amount of time necessary to re heat in the morning.
It takes the furnace about an hr to get back up from 57 to the 69 I
ask for in the morning with the outside temp in the single to teen
digits (Michigan)

In the mornings the heat will turn on around 6 to have the house warm
by 7. The odd thing is that the furnace will run for about 30 minutes
or more, then it will then stop for about a minute or 2 then turn
back on continuing to heat. At the time the furnace turns off it
might have raised the temp from 57 to 65 or so, on its way to 69.

The stat has a "heat" indicator on the display and while it is
blinking "recovery" indicating that the system is trying to re heat
the house, the "heat" indicator will turn off.

The fan will run for a few minutes after the heat indicator turns
off, then the whole system will sit for a minute or too, then it will
turn back on, and work its way back up to the desired temp.

Is this normal? should the furnace not run straight thru up until it
reaches the desired temp?


I've got an older (17 yrs??) furnace Thermo Pride Furnace which I
believe has an 80% efficiency (based on btu IN/OUT calcs on the
stickers. The house is about 30 yrs old 2200 sq/ft.

Thanks for any and all comments / info
