Address Descriptor Application Description
68 UOC GEX MIN 2601, 2603, 2611,
2613
Minimum general exhaust in unoccupied mode.
{69} TOTL SUPPLY 2601, 2602, 2603,
2611, 2612, 2613
Point 35 + Point 61. This is the measured value of the airflow delivered
to the room by the supply terminal plus the value of any supply airflows
not connected to the LRC.
70 SUP P GAIN 2601, 2603, 2611,
2613
Feedback gain. Used to tune supply flow control.
70 SUP1 P GAIN 2602, 2612 Feedback gain. Used to tune the flow control loop.
71 UOC SUP MAX 2601, 2603, 2611,
2613
Maximum supply in unoccupied mode.
72 UOC SUP MIN 2601, 2603, 2611,
2613
Minimum supply in unoccupied mode.
73 DO DIR.REV 2600, 2601, 2602,
2603, 2611, 2612,
2613
Makes it possible to reverse the action of the output TRIACs.
{74} GEX MAX 2601, 2603, 2611,
2613
Currently active maximum general exhaust.
{75} GEX MIN 2601, 2603, 2611,
2613
Currently active minimum general exhaust.
{76} SUP MAX 2601, 2603, 2611,
2613
Currently active maximum supply.
{77} SUP MIN 2601, 2603, 2611,
2613
Currently active minimum supply.
{79} TEMP LOOPOUT 2601, 2602,
2603, 2611,
2612, 2613
Value calculated by the room temperature PID algorithm. It indicates
the thermal load on the room.
{81} SUP DMPR CMD 2601, 2603,
2611, 2613
Tells the supply damper how fast to move. Positive means opening.
Negative means closing.
{83} VOL DIFFRNC 2601, 2602,
2603, 2611,
2612, 2613
Difference between measured airflow into the room, and measured
airflow out. Equal to Point 53 - Point 69
84 TRACK METHOD 2601, 2603,
2611, 2613
Details. When the value is STPT, the supply flow follows the GEN EXH
STPT. When the value is FLOW, the supply flow follows GEN EXH
VOL.
{85} GEX FLO STPT 2601, 2603,
2611, 2613
Desired value of the general exhaust. The controller selects the lowest
value that will lead to adequate supply flow, and correct pressurization.
{85} SUP2 STPT 2602, 2612 Desired value of the supply 2 set point.
{88} VOL DIF STPT 2601, 2602,
2603, 2611,
2612, 2613
Desired value for the flow difference. This value can be selected and
adjusted to achieve room pressurization.

{89} OTHER EXH 2601, 2602,
2603, 2611,
2612, 2613
Value of any exhaust airflows not connected to the LRC. Must be
entered to the controller to account for flows it can not detect.
90 OC V ALM LVL 2601, 2602, Ventilation alarm level in occupied mode.
