It has been suggested that the thermostat is in adaptive recovery mode
because I switched the scheduled temperatures. An I have seen the
recovery indicator on the thermostat so that must be the case.

I think I understand that while in this mode, the thermostat does NOT
call upon the aux heater. The manual says it can take about a week for
the system to adjust. But does this recovery mode only kick-in around
the time(s) that the schedule changes? It seems like that is the only
time I see the recover indicator shown on the thermostat.

I feel the cold blasts at times other than when the schedule changes and
I see the recovery indicator on the thermostat. So these may be defrost
periods. Would the thermostat in recovery mode have any effect on the
use of the aux heater during defrost?

I feel that with your help I am starting to focus in on the problem and
actually understand a little more of how my system works. Thanks again
for all your time and help. Happy holidays.

Obviously your not happy or comfortable with the way the system is
operating. We can't check it or make any needed repairs or adjustments
through the computer. Instead of screwing around on here and never *KNOWING*
if its its right or not, make the call to your favorite *competent*,
licensed, insured, professionally trained, HVAC technician to come check the
system, make any needed repairs/adjustments, and service the system. This
will remove all doubt if its right or not. Ask your servicing technician
about a prefered customer service agreement.
No, its not gonna be free, and I highly discourage using the lowest priced
contractor. The required training, education and experience are not free,
nor is the truck, nor or the spare parts inventory on the truck...for that
matter, the techs time isn't free either. Small companies are a good thing
because you know that the teck will most likely either be the owner or a
very well trained tech, as opposed to the large companies where you never
know who your gonna get.

In a non-union world, where there is no actual apprenticeship or journeyman
levels. Master level is achieved through passing SBCCI, NATE, or other
recognized equivelancy exams. Master level is *REQUIRED* to even qualify to
take the SBCCI Contractor exam. Here, the big companies only have one or 2
that are certified Masters, and most of the rest of their "techs" are
anybody that can fog a mirror. With *legitimate* small companies, its a
different matter entirely.
