    OK, so let's say it is 20 degrees outside and the return temp is 65 degrees. If the device is pulling in 80 CFM from outside and 140 CFM from inside, that would give the machine a mixed temperature...

    Thanks for the quick reply, TB. The dehumidification function would be great. However, all of the Ultra-Aires note that the inlet temperature needs to be 49F Min, 95F Max - so in wintertime, I...
