Service Configuration Selection Screen — The Service Configuration Selection screen is a menu of Service screens which can be accessed by the user. The following screens are available: Airflow Service Configuration, Terminal Service Configuration, Option Service Configuration, and Sec- ondary Damper Service Configuration.

AIRFLOW SERVICE CONFIGURATION SCREEN — The Airflow Service Configuration Table is used to configure the pressure independent and backup pressure dependent set points. See Table 9.

Pressure Independent — Pressure Independent (PI) set points should be configured for pressure independent operation applications.

Cool Minimum (PI) — This configuration is the minimum airflow the terminal will control to when the equipment is in Cooling mode (or Fan Only mode) or free cooling. The space requirements for cooling must be at a minimum, or the terminal is a fan powered terminal and the space requirements are for heat.

Cool Minimum: Units

CFM

Range

0 to 9999 (Limited by

the High Velocity pressure limit alarm)

Default Value

0

Cool Maximum (PI) — This configuration is the maximum airflow the terminal will control to when the equipment is in Cooling mode (or Fan Only mode) or free cooling and the space requirements for cooling are at a maximum.

Cool Maximum: Units

CFM

Range

0 to 9999 (Limited by

the High Velocity pressure limit alarm)

Default Value

4000

Terminal Reheat (PI) — This configuration is for single duct units with ducted reheat. The desired airflow is configured at which the reheat will provide optimum performance. This val- ue is compared to the Minimum Cool value and the greater of the two values is used to determine the airflow set point.
