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.

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
