View Full Version : controlling indoor blower on-off times

Can anyone recomend a thermostat that I can program to cycle the indoor blower on -off for about an hour each day. I have a customer who has condensation problems in his attic flex ducts during the winter. The system is used for A/C only during the summer months here in the northeast. Thanks.

TH8000 series thermostats can be programmed to do that, by turning the fan on during one event, and then off the next event.
However, it will cool the house down when it runs the fan in winter. Blocking the return will usually take care of condensation.

He has already blocked the return of which I suggested also. Doing some homework it seems that running the fan once a day fixes the problem. I am guessing that the cooling of the house down will come only from the cold air in the ducts that are in the attic. I would have to say " water or cool air, name your choice." Thanks beenthere.
