Staging occurs as follows for heat pump (AC = 1) units and
(AUXOUT = 3) configured for reversing valve:
If Heating PID STAGES = 2
(HCAP = 50% capacity) energizes CMP1 and CMP2,
then 2 seconds later energizes H3_EX_RVS.
(100% capacity) energizes HS1 and HS2.
If Heating PID STAGES = 3
(33% capacity if) energizes CMP1 and CMP2, then
2 seconds later energizes H3_EX_RVS.
(66% capacity) energizes HS1
(100% capacity) energizes HS2
AUXILIARY OUTPUT — The Auxiliary Output function is
used to define the specific use of the Auxiliary Output on the
controller board.
The output will be energized or deenergized by the appro-
priate algorithm that uses that specific output.
Auxiliary Output is displayed as one of the following:
0 = None 2 = Heat Stage
1 = Exhaust Fan 3 = Reversing Valve
Auxiliary Output: Range: 0 to 3
Default Value: 3
UNOCCUPIED FREE COOL (NOT USED) — The Unoc-
cupied Free Cool function is used during unoccupied periods to
pre-cool the space using outside air when outside conditions
are suitable.
Unoccupied
Free Cool: Range: Disable/Enable
Default Value: Disable
DEMAND LIMITING — The Demand Limiting function is
used to limit operating capacity of the unit to prevent system
overloads. Both Heating and Cooling capacity is limited.
When the Demand Limit option is enabled, the control will
respond to the Loadshed Controller commands, such as Red-
line Alert, Shed, Unshed, and Redline Cancel. If equipped with
the expansion I/O board, the control will also respond to the
Loadshed Hardware input.
Demand
Limiting: Range: Disable/Enable
Default Value: Disable
LOADSHED GROUP NUMBER — The Loadshed Group
Number function defines the Loadshed table number (LDSH-
DxxS, where xx is the configured loadshed group number) that
the controller will respond to when a broadcast for Redline/
Loadshed has been detected on the CCN bus.
Unoccupied
Free Cool: Range: 1 to 16
Default Value: 1
CCN, BROADCAST OAT, ENTHALPY, OAQ — Config-
ures the controller to CCN broadcast any or all of the point
values for Outside Air Temperature (OAT), Enthalpy (ENTH),
and Outdoor Air Quality (OAQ).
Example: To broadcast OAQ and ENTH but not OAT, the cor-
responding bitmap is 110; the binary equivalent of the decimal
number 6. The configuration decision would then be set to a 6.
CCN Broadcast, OAT, Enthalpy,
OAQ Allowable Entries:
0 — None 5 — OAT and OAQ
1 — OAT Only 6 — ENTH and OAQ
2 — ENTH Only 7 — OAT, ENTH and OAQ
3 — OAT and ENTH
4 — OAQ Only
Default Value: 0 (disabled, no broadcasts performed)
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 de-
gree) 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)
