Override — The Override parameter is used to configure the number of hours and minutes the override will be in effect. The user initiates override by pressing the override button on the space temperature sensor. This will cause the schedule to enter into the Occupied mode. If global scheduling is used, all zones using the global schedule will enter Occupied mode. Pushing the override button during Occupied mode will have no effect.
If the occupancy override is due to end after the start of the next occupancy period, the mode will transition from occupan- cy override to occupied without becoming unoccupied, and the occupancy override timer will be reset.
NOTE: If using the tenant billing function, the override hours set point must be configured between 1 and 3 hours.
Override: | Units | Hours: Minutes |
| Range | 00:00 to 24:00 |
| Default Value | 00:00 |
Broadcast Acknowledger — This configuration defines if the zone controller will be used to acknowledge broadcast messag- es on the CCN bus. One broadcast acknowledger is required per bus, including secondary busses created by the use of a bridge.
Broadcast |
|
Acknowledger: Range | No/Yes |
Default Value | No |
Set Point Group Number — The Set Point Group Number is used to define the current zone controller as a part of a group of zone controllers which share the same set points. All zone con- trollers with the same Set Point Group Number will have the same set points. The set points are broadcast to the group by the zone controller defined by the Global Set Point Master config- uration. A value of 0 is a local schedule. Values 1 to 16 are used for global scheduling.
Set Point |
|
Group Number: Range | 0 to 16 |
Default Value | 0 |
Global Set Point Master — This configuration defines if the current zone controller will broadcast its set point values to the other zone controllers which are made part of the same group by configuring the Set Point Group Number.
Global Set Point |
|
|
Master: | Range | No/Yes |
| Default Value | No |
Maximum Offset Adjustment — This configuration deter- mines the maximum amount that the set point will be biased (up or down), by adjusting the slide bar on the space tempera- ture sensor (if installed).
Maximum Offset |
|
|
Adjustment: | Units | delta F (delta C) |
| Range | 0 to 15 |
| Default Value | 2 |
Control Options — The Control Options configuration deter- mines whether the zone controller will use a humidity sensor or an indoor air quality sensor. A configuration of 0 means no sensors are used. A configuration of 1 means a Humidity Sen- sor is used. A configuration of 2 means an IAQ Sensor is used.
Control Options: Range | 0 to 2 |
Default Value | 0 |
Humidity Control — These configuration values define the calculation parameters for determining the airflow needed to correct a high humidity problem in the space. The Maximum Output Value is measured in percentage of nominal terminal cfm.
Proportional |
|
|
Gain: | Range | 0.0 to 9.9 |
| Default Value | 1.5 |
Integral Gain: | Range | 0.00 to 9.99 |
| Default Value | 0.30 |
Maximum Output |
|
|
Value: | Range | 0.0 to 100.0% (max cool |
|
| cfm) |
| Default Value | 100.0 |
Indoor Air Quality Control — These configuration values de- fine the calculation parameters for determining the airflow needed to correct a high incidence of air pollution contami- nants in the space, such as CO2. The Maximum Output Value is measured in percentage of nominal terminal cfm.
Proportional Gain:Range | 0.00 to 9.99 | |
| Default Value | 0.10 |
Integral Gain: | Range | 0.00 to 9.99 |
| Default Value | 0.03 |
Maximum Output |
|
|
Value: | Range | 0.0 to 100.0% (max cool |
|
| cfm) |
| Default Value | 100.0 |
→IAQ Sensor Low Voltage — This configuration defines the lowest voltage which should be read from the air quality sensor.
IAQ Sensor |
|
|
Low Voltage: | Range | 00.0 to 10.0 |
| Default Value | 0.0 |
IAQ Sensor High Voltage — This configuration defines the highest voltage which should be read from the air quality sen- sor.
IAQ Sensor |
|
|
High Voltage: | Range | 00.0 to 10.0 |
| Default Value | 10.0 |
IAQ Low Reference — This configuration defines the value in parts per million which correlate to the low voltage reading from the air quality sensor.
IAQ Low |
|
|
Reference: | Units | ppm (parts per million) |
| Range | 0 to 5000 |
| Default Value | 0 |
IAQ High Reference — This configuration defines the value in parts per million which correlate to the high voltage reading from the air quality sensor.
IAQ High |
|
|
Reference: | Units | ppm (parts per million) |
| Range | 0 to 5000 |
| Default Value | 2000 |
SECONDARY DAMPER SERVICE CONFIGURATION SCREEN — The Secondary Damper Service Configuration screen is used to configure the secondary damper settings. See Table 12.
Zone Pressure Control — The Zone Pressure Control config- uration determines whether the primary and secondary control- lers will be configured for zone pressure control.
Zone Pressure |
|
|
Control: | Range | Dsable/Enable |
| Default Value | Dsable |
Dual Duct Type — The Dual Duct Type setting configures the secondary controller for the correct dual duct type. A value of 0 configures the type to None. A value of 1 configures the type to Second Inlet (Hot Deck). A value of 2 configures the duct to Total Probe (terminal outlet).
Dual Duct Type: Range | 0 to 2 |
Default Value | 0 |
800 | 42 |
