SET POINT OFFSET (T-56) — This variable displays the
degrees of offset when using a 33ZCT56SPT space tempera-
ture sensor with set point adjustment. The slidebar on the
sensor will adjust the desired temperature in that zone, up or
down, when it is moved. The Set Point Offset (T-56) variable
can disable set point offset (set to 0).

COOL MASTER REFERENCE — This variable displays
the cooling master reference from the set point schedule. This
should be the occupied cool set point when the zone is in
occupied mode or the unoccupied cool set point when the zone
is in unoccupied mode. This variable will display any space
temperature sensor slidebar offset that is being applied.

rent damper reference position.

SUPPLEMENTAL HEAT LOCKOUT — This variable dis-
plays if Supplemental Heat is locked out by the outside air
temperature or if forced. If this variable is set to Yes, then
Supplemental Heat is locked out.

HEAT MASTER REFERENCE — This point displays the
occupied heat set point if occupied, or the unoccupied heat set
point if unoccupied. This variable will display any space
temperature sensor slidebar offset that is being applied.

HEAT SUBMASTER REFERENCE — If heat is enabled,
this variable displays the desired supply air temperature calcu-
lated to heat the space. This is a result of the heating PID loop
calculation.

TEMPERATURE CONTROL POSITION — This variable
displays the airflow set point determined from the temperature
loop calculation. The zone controller compares the temperature
demand and DCV loops. The greatest of the two will become
the primary damper airflow reference.

DCV DAMPER % — This variable displays the damper set
point determined by the demand control ventilation loop
calculation. The zone controller compares the demand of the
temperature and demand control ventilation loops. The greatest
of the two will become the Damper Reference.

COOLING IN EFFECT — This variable displays if the air
source is in the Cooling mode and if the terminal is using the
cooling damper set points.
Cooling In Effect: Display Range
No/Yes

HEATING IN EFFECT — This variable displays if the air
source is in the Heat mode and if the terminal is using the
heating damper set points.

DCV IN EFFECT — This variable indicates if the DCV con-
trol is active.

CLEAR ALARMS — This variable displays the commanded
state of the Clear Alarms function. If this decision is forced to
Yes
, all alarms in the Alarm History Table will be cleared and
this decision will automatically be set back to
No
.

LOADSHED FUNCTION REDLINE — This variable dis-
plays whether the zone controller is currently participating in a
redline event and as a result has relaxed its current set points by
the amount configured in the Options Configuration Table.
Redline:
Display Range
No/Yes
Network Access Read Only
LOADSHED — This variable displays whether the zone con-
troller is currently participating in a loadshed event. If the
loadshed event was preceded by a redline event and was in
redline when the loadshed command was received, then the
zone controller will drop one stage of heat if in heating mode
and provided there is more than one stage available. If in
cooling mode, the zone controller will raise the cooling set
point by the amount configured in the Options Configuration
Table, if this will cause the space to be satisfied.
Loadshed:
Display Range
No/Yes
Network Access Read Only
LOADSHED TIMER — This variable displays the timer that
is started during a redline or loadshed event to automatically
timeout the event after a user programmable time limit. The
time limit is configurable in the Option Service Configuration
Table.
NOTE: The redline/loadshed response will be automatically
cancelled upon termination of the current occupied period.
Loadshed Timer: Display Range
0 to 240 min

Zone Commissioning Maintenance Table —
The
Zone Commissioning Maintenance Table (ZONECOMM)
displays and permits the setting of damper position for the
purpose of damper actuator transducer calibration. It also
allows the user to test the fan on series and parallel fan powered
terminals and to test the heat outputs. It displays the supply air
temperature for the heat test and will display an alarm if the
calibration fails. See Table 23.
