Actual indication of the status of the override switch (not
physically available on all temperature sensor models) at the
room temperature sensor. ON indicates that the switch is
being pressed. OFF indicates that the switch is released.
Valid input: ON or OFF.
OCC.UNOCC

All
Indicates the mode that the controller is operating in with
respect to the override switch. NIGHT indicates that the
switch has not been pressed and the override timer is not
active. DAY indicates that the switch has been pressed and
the override timer is active. The controller then uses a day
mode temperature setpoint. This point is only in effect when
DAY.NGT indicates night mode.
VOL DIF ALM
{22}
2931
Alarm point. ON means room pressurization may not be
adequate.
NET ALM CMD
{23}
2931, 2997
The alarm data sent in to PRC from the network.
OCC SWIT DI2
{24}
2931, 2997
Actual status of a contact connected to the controller at DI 2
(screw terminals 15 and 16). ON indicates that the contact is
closed; OFF indicates that the contact is open. If a wall
switch is used, it is connected to DI 2.
DI 2

2931
An occupancy input. This value comes to the LCM from the
network or from a schedule.
NET OCC CMD
{29}

Indicates the mode in which the controller is operating.
Occupied temperature setpoints will be used in DAY mode.
Unoccupied temperature setpoints will be used in NGT
mode. This point is normally set by the field panel.
GEX AIR VOL
{30}
2931, 2997
Measured value of the airflow from the room through the
general exhaust terminal.
AIR VOLUME 2
{30}
2997
Measured value of airflow in cfm (lps).
OCC SUP MAX
{31}
2931
The maximum amount of air in cfm (lps) to be supplied to the
space during occupied periods.
OCC SUP MIN
{32}
2931
The minimum amount of air in cfm (lps) to be supplied to the
space during occupied periods
OCC GEX MAX
{33}
2931
