KMC Controls FlexStat series Operation Manual page 15

OA MAX = The maximum allowable % of outside
air damper position (40% default) for
ventilation (not cooling) purposes. The
value is determined using DCV DAMPER
SETUP.
OA PURGE = During the 60 minutes prior to
scheduled start time, the outside air
damper will open to this position (0%
default) to perform a purge of the zone.
The value is determined using DCV
DAMPER SETUP.

VENT MODE = Displays (only) in which ventilation
mode the FlexStat is functioning (see
illustration):
• Normal—Typical ventilation during
the occupied period (after Pre-purge,
Startup, or Recovery modes have
finished and returned the ventilation
rate to "normal" operation).
• Pre-purge—If enabled in the
programming (disabled by default),
the space is ventilated with maximum
outside air for 60 minutes before the
occupied start time. (See Startup.)
• Startup—If pre-purge is disabled
(default) and the motion sensor
detects motion during the 20 minutes
after occupied start time, the space is
ventilated with maximum outside air
until 20 minutes after occupied start
time.

• Standby—After the motion sensor has
not detected motion for 30 minutes,
temperature setpoints are adjusted
(down for heating and up for cooling),
and the outside air damper is closed.
• Recovery—After a period in which
the supply fan was off, the space is
ventilated with an increased percentage
of outside air (to compensate for the
previous reduced ventilation).
• Override—Ventilation override has
been manually selected from the DCV
menu, and the space is temporarily
(30 minutes default) driven to the full
ventilation position (for maximum
design occupancy) if it is not already
at that position. See DCV (Demand
Control Ventilation) on page
VENT OVRIDE (MINS) = Amount of time for
Ventilation Override operation (30 minutes
default). See DCV (Demand Control
Ventilation) on page
