Occupied Cooling (31) Ð Indicates that the unit is in the Cooling mode to satisfy its Occupied Cooling set point.

Occupied Fan Only (32) Ð Indicates that the unit is main- taining set point by using a mixture of outside and return air only. No mechanical heating or cooling is being used.

Nighttime Free Cooling (33) Ð Indicates that the supply fan is on and using outside air to precool the space served by the unit. Unit must be con®gured for nighttime free cool-

ing ( ). (This mode is enabled by .)

Smoke Pressurization (34) Ð Indicates that the unit is in the Pressurization mode. This mode is issued from the ®re system panel. Refer to Table 15 for the state of the items controlled.

Smoke Evacuation (35) Ð Indicates that the unit is in the Smoke Evacuation mode. This mode is issued from the system panel. Refer to Table 15 for the state of the items controlled.

Smoke Purge (36) Ð Indicates that the unit is in the Smoke Purge mode. This mode is issued from the ®re system panel. Refer to Table 15 for the state of the items controlled.

Fire Shutdown (37) Ð Indicates that the unit is in the Fire Shutdown mode. This mode is issued from the ®re system panel or local smoke detector. Refer to Table 15 for the state of the items controlled.

Quick Test (38) Ð Indicates that the unit is in the Quick Test mode. It allows the user to test all inputs and outputs con- nected to the PIC controller. All control routines are deac- tivated when the unit is in this mode. This mode can only be initiated manually when the supply fan status is OFF. (HOA switch is in OFF position.) In order to reactivate all

the con®gured control routines, press and then press .
