Programmable fan must be enabled in the Installer Setup.

Thank you for the prompt reply, assume I can access the “installer setup”

Recently have noticed during the “wake period” the fan kicks into high
which sounds like a 747 just above the roof line. I assumed this to be
normal since it would switch back to a lower speed after a two degree
increase in temp. However now I have noticed the high speed roar during
the day with a duration of seconds before switching to a lower speed.
This sequence would repeat itself several times before either shutting off
or remaining at a lower speed.
