GLOBAL SCHEDULE BROADCAST — The Global Sched-
ule Broadcast setting configures the controller to broadcast or
receive a global schedule. If set to Yes, the controller will act as
a global schedule master and its schedule will be broadcast to
the CCN. If set to No, the controller will not broadcast a global
schedule and it will receive the configured schedule number.
Global Schedule
Master:
Range: No/Yes
Default Value: No
BROADCAST ACKNOWLEDGER — The Broadcast Ac-
knowledger setting configures the controller to recognize
broadcast messages that appear on its CCN bus.
NOTE: For proper CCN bus operation, there should be only
one device per CCN bus that is configured as the Broadcast
Acknowledger.
Acknowledger:
Range: No/Yes
Default Value: No
SCHEDULE NUMBER — The Schedule Number deter-
mines which Global Occupancy Schedule that the controller
will follow. A value of 64 disables global occupancy from
CCN and will decide Occupancy from its local schedule. A
value between 65 and 99 will allow the controller to follow the
global occupancy schedule of the number broadcast over CCN.
Occupancy Schedule
Number
Range: 64 to 99
Default Value: 64
TIMED OVERRIDE HOURS — The Timed Override Hours
function is used to configure a timed override duration by
entering the number of hours the override will be in effect.
Pressing the override button on a space temperature sensor will
cause an override.
Timed Override
Hours:
Range: 0 to 4
Default Value: 0
LINKAGE THERMOSTAT — The Linkage Thermostat start
time biases allow the installer to configure the time per degree
the space should take to recover in the Heat and Cool modes
for optimum start with a Linkage Thermostat. These numbers
will be used to calculate the Start Bias time.
Cool Start Bias:
Units: Minutes/Degree
Range: 0 to 60
Default Value: 10
Heat Start Bias Units: Minutes/Degree
Range: 0 to 60
Default Value: 10
FILTER TIMER HOURS — The Filter Timer Hours config-
uration determines when the filter status will display a “Dirty”
alarm. When the Filter Timer Hours is configured to a value
other than zero and fan run time exceeds the value configured,
the filter status will display “Dirty” and a CCN alarm will be
generated. Setting the configured Filter Timer Hours value to
zero will disable the alarm condition. The value of the timer is
stored in EEPROM to protect it in the event of a power failure.
The value is stored every 24 hours.
Filter Timer
Hours:
Range: 0 to 99
Default Value: 15 (where 15*100=1500)
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.
Indoor Air Quality
Preoccupancy
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 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.
Indoor Air Quality
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
correlate to the low and high voltage readings from the sensor.
Low Reference specifies 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 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 — The Outdoor Air
Quality sensor defines the value in parts per million (ppm)
which correlate to the low and high voltage readings from the
sensor.
