INDOOR AIR QUALITY PRIORITY LEVEL — The Indoor
Air Quality Priority Level, when set to Low, ensures that com-
fort is not being compromised by bringing in too much outdoor
air to maintain IAQ set point. When an override condition
takes place, IAQ control is disabled, and Economizer Mini-
mum Position is set to the user configured value MDP. When
set to High, IAQ control is always active regardless of indoor
comfort conditions. The controller will temper cold air OAT
<55 F to prevent cold blow.
Indoor Air Quality
Priority Level: Range: High/Low
Default Value: Low
INDOOR AIR QUALITY PREOCCUPANCY PURGE —
The Indoor Air Quality Preoccupancy Purge brings in fresh
outdoor air before the Occupied mode begins. The IAQ Pre-
Occupancy Purge is used to lower carbon dioxide levels below
the IAQ set point before Occupied mode starts.
The Purge is started two hours before the occupied time and
lasts for the specified duration.

Purge: Range: Disable/Enable
Default Value: Disable
INDOOR AIR QUALITY PURGE DURATION — The
Indoor Air Quality Purge Duration specifies the duration of
IAQ Pre-Occupancy purge. The Purge is started two hours
before the occupied time and lasts for the specified duration.
Indoor Air Quality
Purge Duration: Display Units: Minutes
Display Range: 0 to 60
Default Value: 5
INDOOR AIR QUALITY DELTA SET POINT — The
Indoor Air Quality Delta Set Point specifies the highest
Indoor Air Quality level (measured in ppm) allowed within the
space whenever unit is in Occupied mode (or Supply Fan On
for units with Thermostat control) and Indoor Air Quality
sensor is installed.
Indoor Air Quality
Delta Set Point: Display Units: PPM (parts per
million)
Display Range: 1 to 5000
Default Value: 650
INDOOR AIR QUALITY MAXIMUM DAMPER POSI-
TION — This point displays the upper limit of the Indoor Air
Quality minimum damper position calculated by the IAQ
control.
For example, IAQ is calculating 100% Minimum Damper
Position, but this decision is set to 50%, IAQ Minimum Damp-
er Position will be clamped to 50%.
NOTE: When IAQ priority is set to HIGH, this value must
reflect the maximum outdoor air percent that the equipment
can heat or cool at worst conditions.

Maximum Damper
Position: Display Units: % Open
Display Range: 0 to 100
Default Value: 50
INDOOR AIR QUALITY SENSOR — The Indoor Air Qual-
ity sensor defines the value in parts per million (ppm) which
correlates to the low and high voltage readings from the sensor.
Low Reference specifies the Low Point of the Indoor IAQ
Sensor Range in ppm.
Low Reference: Units: PPM (parts per million)
Range: 0 to 5000
Default Value: 0
High Reference specifies the High Point of the Indoor IAQ
Sensor Range in ppm.
High Reference: Units: PPM (parts per million)
Range: 0 to 5000
Default Value: 2000
OUTDOOR AIR QUALITY SENSOR (NOT USED) —
The Outdoor Air Quality sensor defines the value in parts per
million (ppm) which correlates to the low and high voltage
readings from the sensor.
Low Reference specifies the Low Point of the Outdoor IAQ
Sensor Range in ppm.
Low Reference: Units: PPM (parts per million)
Range: 0 to 5000
Default Value: 0
High Reference specifies the High Point of the Outdoor
IAQ Sensor Range in ppm.
High Reference: Units: PPM (parts per million)
Range: 0 to 5000
Default Value: 2000
OUTDOOR AIR QUALITY LOCKOUT POINT (NOT
USED) — When set to non-zero value, the IAQ algorithm
will compare the Outdoor IAQ reading against this decision
and disable the IAQ control whenever the value of OAQ
exceeds this configured value.
Outdoor Air
Quality Lockout
Point: Range: 0 to 5000
Default Value: 0
SERVICE PASSWORD — The Service Password function
defines the password needed to access the controller via the
Navigator interface.
Service Password: Range: 0000 to 9999
Default Value: 1111
PASSWORD ENABLE — The Password Enable function is
used to require a password when attempting to access the con-
troller via the Navigator interface.
Password
Enable: Range: Enable/Disable
Default Value: Disable
METRIC DISPLAY — The Metric Display function is used
to toggle the Navigator display between US and Metric units.
Metric Display: Range: On/Off
Default Value: Off
Occupancy Maintenance Screen —
The Occupan-
cy Maintenance screen is used to check the occupied schedule.
Information concerning the current occupied period is dis-
played. See Table 14.
