Hello,
I just purchased my mom house in Florida and she had a list for leaving the home vacant,
but my question is while I am here. The system has a humidistat wired in series along with
the thermostat. At first it appears the system is working fine, but I notice at night when
things are quiet that the tstat fan is constantly running. If I get up on a chair I can feel
a gentle air flow at all times.
Is this normal or something to be concerned about?

Thanks,
Joe
