Setting the Fan to ON, AUTO, or CIRC
The fan has 3 settings: On, Auto, and Circ. Press the
button to switch
among the three.
ON: The fan is on constantly. The room temperture, set points, and status
of the heating and cooling equipment has no effect on the fan.
AUTO: When there is a call for heating or cooling the fan will turn on.
CIRC: The fan operates in a cycle of on for 10 minutes and off for 20
minutes. When there is a call for heating or cooling the cycle stops
and the fan responds to the call. The fan circulation cycle resumes
when the call for heating or cooling is satisfied.
