Hi;
I had an April Aire 650 Whole House humidifier installed in my house. It is a bypass model. They ran a thermocouple outside and I am not quite grasping why. I am not questioning the install, I am just trying to understand the concept. I can see where the unit would like to know the temperature of the air so it can figure out the relative humidity, but to take that reading outside doesn't seem logical since it is using the return air in the house. It would seem to make more sense to me to place the thermocouple in the return air duct. Am I missing something? Please explain if you have the time. Thanks Pat |

Thanks Pat You set the unit till you see condensation somewhere, usualy on glass, then back it off till there is no condensation and leave that setting, it tracks the right amount of moisture you can have based on outside temp so no damage occurs to your home from over humidifying, which leads to mold and rot. You have a great humidifier. |

When it gets very cold line -20º you don't want the interior humidity to be as high as you might want it when it is say 40º. If you tried to maintain 60% humidity when it is -20º outside, you would tend to get a lot of moisture freezing on windows, condensing in wall insulation etc. You go Joe :-) |

Bravo Meester Meehan. I've had to explain that to a lot of customers, but methinks I will just print your answer out on little cards... ;-] |
