Default:
AS
(AS AD):
The fan is on Auto during occupied periods. The Med and
High speeds operate automatically on a temperature error from the
setpoint. The Low speed operates Auto on demand. When there is
no demand, the Low speed shuts down. The Low speed is only re-
activated when there is a heating or cooling demand.
(AS):
The fan is always on during occupied periods. The fan is on
Auto during unoccupied periods. The Low, Med, and High speeds
operate automatically on a temperature error from the setpoint.
