For heating applications, Heating Fan is set to Auto
by default but can be disabled if needed (such as for
an FCU that is factory wired to run at a xed speed
or for a baseboard heater without a fan). The Heating
Fan selection is only available when the application
supports heating and either Occupied fan or Unoc-
cupied fan is set to Auto.
NOTE: For a Fan Fail Alarm, see Sensor Setup on
page 9 and Alarms on page 23.

NOTE: If a dehumidication option is enabled, the
Space Humidity Alarm will also be enabled.

NOTE: To see the dehumidication option in the
Additional Setup menu for a HeatPump
application, select an Aux. Heat option
other than None (the default).

A motion/occupancy sensor may be enabled (the
default) to trigger occupancy override (enabled by
default, but only functional during scheduled o
times) and occupancy standby in relation to the
scheduled on and o times. (See the chart.)
During scheduled OFF (unoccupied) times,
temperature is controlled according to the seing of
the appropriate heat or cool setback (see Setpoints
on page 25). Occupancyoverride (for 1 hour as a
default) starts when the sensor detects motion.
Temperature will start being controlled according
to the appropriate setpoint. Occupancy override will
end (with the default seing) 1 hour after motion
was last detected. The length of occupancy override
is congurable in the System menu. See System
Modes on page 25.
During scheduled ON (occupied) times, temperature
is controlled according to the seing of the appro-
priate heat or cool setpoint. If enabled, occupancy
standby sets the temperature back or up (according
to the heating/cooling mode) by the Oset amount
when no motion is detected for the Timer amount (30
minutes by default). The normal setpoint is restored
when motion is detected twice (to reduce false detec-
tions) within three minutes.
NOTE: Occupancy standby, when activated, lets
the temperature go down or up (according
to the relevant mode) by the Oset amount
(3° by default), not the Setback seing in the
Setpoints menu (which usually has a larger
temperature dierential meant for a longer
o time).
NOTE: When the Advanced DCV mode is selected,
Standbyisenabledbydefaultandwhen
