AirCycler, what it does and does not do
I had stated:
>>AirCycler is at heart a Lstiburek product. It begins its "off-time" counter
>>upon the end of an AC call, so the coil gets its drying time.
>>VisionPro runs only at random so some of the time it is adding house humidity via the coil.
>>I have to wonder how quickly a coil will dry after a cooling call when sitting in an
>>enclosed cabinet with no air circulation. You might get a little air movement from
>>natural convection as the ductwork, air handler, coil, etc begin warming up at their
>>different rates, but I've seen coils hold onto their moisture for some time when
>>there's no air moving past them and the air surrounding the coil is saturated with moisture.
Good observation on the dynamics of moisture on a coil, I too wonder what is the answer. Let me emphasize that the AirCycler ensures its function is dormant for a time period following a cooling call. It does not inhibit the rest of the system from doing what it is designed to do.
In the case of Trane/A-S and its "Comfort-R" function, it is my understanding there is a period of reduced airflow following a cooling call. I don't claim to understand it all but trust that Trane engineers know what they are doing. Per my understanding, VisionPro could interfere if its random on-time happened to occur then, preventing the Comfort-R algorithm from being completed as Trane designed. AirCycler is designed so it would not interfere.
If any of this is erroneous, I would appreciate a correction. However it sounds as if you are knocking AirCycler on the basis of this, when if anything deserves a knock it is VisionPro.
