UNOCCUPIED HIGH — The Unoccupied High set point de- scribes the high temperature limit of the space during Unoccu- pied mode.
Unoccupied High: Units: | Degrees F (Degrees C) |
Range: | 45.0 to 99.9 |
Default Value: | 90.0 |

| Default Value: | 65.0 |
UNOCCUPIED OAT LOCKOUT TEMPERATURE — The Unoccupied OAT Lockout Temperature describes the low- est Outdoor Air Temperature allowed for Unoccupied Free Cooling operation. This function is also used by IAQ Pre- Occupancy Purge control to determine the minimum damper position for IAQ Purge.

Service Configuration Selection Screen — The Service Configuration Selection screen is used to configure the service set points of the PremierLink™ controller. See Table 14.
COOLING PID — The PremierLink controller reads the space temperature sensor and compares the temperature to he current high set point. If it exceeds the set point, and cooling is configured and available, the controller then calculates the re- quired supply air temperature to satisfy the given conditions.
The Cooling PID (Proportional/Integral/Derivative) in- cludes the following set points: Proportional Gain, Integral Gain, Derivative Gain, and Starting Value.
Proportional Gain: | Range: | 0.0 to 40.0 |
| Default Value: | 6.0 |
Integral Gain: | Range: | 0.0 to 10.0 |
| Default Value: | 3.0 |
Derivative Gain: | Range: | 0.0 to 20.0 |
| Default Value: | 5.0 |
Starting Value: | Units: | Degrees F |
| Range: | 40.0 to 90.0 |
| Default Value: | 70.0 |
