programmable thermostat with fan control
Need some help. A long time ago I found some items. These items where programmable thermostats with a fan schedule. So I could turn on only the fan with time/days.
Any one have some links to these?
the Honeywell 8000 has a feature called circulate.............it cycles the blower on and off and will run about 35% of the time
Just my personal preference, is Robertshaw 9700/9800 series...with 6 programmable periods per day, including period run of the fan, or intermittent run as well.
Hopefullt the link works.
Not to knock Honeywell too badly since I do'nt have one, is how theirs operates on a "Cycles per hour" rather than actual temperature differential for turning the furnace on and off. With the Robertshaw, i can tell the thermostat 1.5F differential and that's what it runs within (2nd Stage @ 2F or30 min).
Hope this helps rather than confuses.
Any Honeywell VisionPro will work, you can program the blower to do diffrent things..
