Address Descriptor Application Description
2613
{15} HOOD SIG AI3 2601, 2602, 2603,
2611, 2612, 2613
Voltage that tells the LRC how much air the fume hood(s) is/are
exhausting.
16 VENT ALM DEL 2601, 2602, 2603,
2611, 2612, 2613
Delay period that prevents “nuisance alarms” on the air change rate.
17 VENT ALM ENA 2601, 2602, 2603,
2611, 2612, 2613
When this is set to “yes”, the VENT ALM point can drive the ALARM
DO8.
18 OCC SWIT ENA 2601, 2602, 2603,
2611, 2612, 2613
Connects Point 24 to Point 45. If this point is disabled, it does not affect
occupancy.
{19} OCC BUTTON 2600, 2601, 2602,
2603, 2611, 2612,
2613
State of the push button switch on the thermostat. The momentary
switch is only ON when the button is pushed. The value of this point
provides no information on the occupancy state of the room.
21 OCC DISPLAY 2600,2601, 2602,
2603, 2611, 2612,
2613
Occupancy state of the LRC; drives display on thermostat.
22 VOL DIF ALM 2601, 2602, 2603,
2611, 2612, 2613
Alarm point. ON means room pressurization may not be adequate.
{23} NET ALM CMD 2600, 2601, 2602,
2603, 2611, 2612,
2613
Alarm data sent in to LRC from network.
{24} DI 2 2600 State of a switch wired to the LRC.
Closed contact = ON = occupied.
{24} OCC SWIT DI2 2601, 2602, 2603,
2611, 2612, 2613
State of a switch wired to the LRC.
Closed contact = ON = occupied.
{25} BUTTON CMD 2600, 2601, 2602,
2603, 2611, 2612,
2613
LRC’s interpretation of Point 19. Records a user’s request to change
occupancy.
26 GEX P GAIN 2601, 2603, 2611,
2613
Feedback gain. Used to tune general exhaust flow control loop.
26 SUP2 P GAIN 2602, 2612 Feedback gain. Used to tune flow control loop in Supply Terminal 2.
{27} ALM SWIT DI4 2601, 2602, 2603,
2611, 2612, 2613
State of switch wired to the LRC. May be used to pick up alarm
information from some other device in the room.
28 ALM SWIT ENA 2601, 2602, 2603,
2611, 2612, 2613
When this is set to “yes”, the ALM SWIT DI4 point can drive the ALARM
DO8.
{29} NET OCC CMD 2601, 2602, 2603,
2611, 2612, 2613
An occupancy input. This value comes to the LRC from the network or
from a schedule.
{30} GEX AIR VOL 2601, 2603, 2611,
2613
Measured value of the airflow from the room through the general
exhaust terminal.
{30} SUP2 AIR VOL 2602, 2612 Measured value of the airflow from the room through the general
exhaust terminal.

31 OCC SUP MAX 2601, 2603, 2611,
2613
Maximum supply in occupied mode.
31 SUP1 MAX 2602, 2612 Maximum supply flow allowed from terminal 1.
