Programable Thermostat with Fan timer?

[OKnewguy]

Hey gang, I have been searching the web and am not having much luck. I thought I would ask the TBN brain trust.
Here is the deal. We have a 1965 house and over the years have done a ton of things to help the efficiency (new windows, doors, heat and air, tons of insulation). We are saving a ton of money now and everything is working pretty darn well. This winter (the first with the new attic insulation) we have an issue with the house getting cool in spots but not in the central part where the thermostat is. We never had this problem before, because the heat would run more often and equalize the air temp.
Is there a thermostat that I can program to have the blower fan come on once on hour for 10 minutes?
Thanks everyone!
Dave

i personally have never seen one like that, doesnt mean it doesnt exist. My Honeywell has a circulate mode that runs the fan 30% of the time at random. So it runs about 18 minutes an hour. but i cant set the time it runs or when it kicks in.

Personally i know how to build a circuit that i could add to your heater board with a timer, but id have to actually build it with a contactor and a timer. As to one already out there//////???????

Is yours one of the high end touch screen units? I just found a touch screen unit that will run the fan for 10 min every 30 minutes. This will work fine, but for close to $200 that is a bunch! I could care less about all the touch screen stuff, our current thermostat is a programable unit about 10 years old that was around $30 or $40 and does everything I want except this.
Thanks, Dave

ya, its a touch screen. most good units are now days. I cant complain, as it works flawless.

that was one of the ones I just found. That would work well, I also found an ip unit that seems pretty cool. Thank you so much for your post. Your phrasing of the fan (circulation mode) is what got me on track to finally get some hits.
Thanks GANG!

my son in law just installed a separate thermostat, to control the blower, nothing else, he has a wood stove, an it gets pretty warm close to it, unless he runs the central units blower, but he has to go turn it on and off, so he installed a thermostat close to the stove, that controls the blower...you might put a thermostat in the area thats cool, to do the same thing??? i don't have a clue how he hooked the thing in..heat pumps are a mystery to me anyway...i think they are right up there with the bumble bee flying...ain't suppose to...
heehaw

So I got a unit this unit http://www.white-rodgers.com/wrdhom/pdfs/instruction_sheets/0037-6814.pdf and for the most part it does work, but when it trips the heat on while it is in circulating mode it goes will just run the fan forever, thinking that it turned the heat on. If it calls for heat with out the circulation mode on everything works well. It seems like it stop the startup cycle of the furnace. Does anyone have any idea's. I called their help line, but never got an answer because it being the weekend.
Any idea's?
Thanks everyone

Here is an idea. Thermal heat guns can be bought for not a large amount of money compared to a few years ago. The guns are fast and quick. Make a check of the cooler areas that you feel are cool. The laser dot is NOT NEEDED to make them work.
I took a thermagraphy course and temperature is read in colour or black and white ( black is the hottest ) that really messes up the brain These thermal guns were $15K

I think I got it figured out finally, there was a adjustment in the menu that was not described in the manual. It switches the unit from furnace to heat pump mode. All seems to be good now. Thanks gang! BTW, on the thermal guns, I have a infrared thermometer and have checked the walls with it, and between that and the remodeling I have done, I have discovered that this house was originally built very well for its time. It was built in 65, but has full insulation in the walls, with house wrap, and it had rock wool in ceiling. The rock wool had settled and then I remodeled and lost a lot of it in area's replace sheetrock and moving walls. So between the new windows and the insulation I added we are about as good as you could expect for a 46 year old house.
I thinks we are good to go, thanks again.
