Well, I got tired of waiting (and having many good heat harvesting days wasted). I came home today to a 93 degree attic! So, I setup the controller a little differently. It currently does not monitor the kitchen temperature. Once the attic gets to 23C / 73F it kicks on. Once it drops to 21C / 70F it kicks off. That is above the temperature the house is kept at (20C / 68F).
Currently, I am monitoring my kitchen's temperature to see what effect the fans have.
As for noise, there is a bit of electric motor hum that is coming down the chimney and the sound of rushing air a little. However, its quieter than when the furnace kicks on.
