Description
MTR2 POS
{53}
2
2963, 2965
The current position of the Motor 2 actuator in percent of full
travel (for use as an auxiliary slave point). This value is
calculated based on motor run time. See
MTR2 TIMING .
GEX FLO COEF
54
2963
The calibration parameter for airflow sensor.
AOV3
{55}
2963, 2965
Displays the voltage signal to AO3.
PRS1DIF STPT
56
2963
The volume differential setpoint used to provide desired
pressurization.
PRS2DIF STPT
57
2963
The volume differential setpoint used to provide desired
pressurization.
REHEAT END
58
2963
Determines how the reheat modulation will be sequenced while
in heating mode. When HTG LOOPOUT is below this value,
then the reheat modulates downward.
TOTL SUPPLY
{59}
2963
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 PRC.
GEXDUCT AREA
60
2963
Area, in square feet (square meters), of duct where the air
velocity sensor is located. This value is calculated by the
portable operator’s terminal or by the field panel depending on
duct shape and size. It is used in calculating all points in units
of cfm, CF, lps, and L.
OTHER SUP
{61}
2963
The value of any supply airflows not connected to the PRC.
Must be entered to the controller to account for flows it cannot
detect.
VOL DIFFRNC
{62}
2963
The difference between measured airflow into the room, and
measured airflow out.
CLG P GAIN
63
2963
The proportional gain value for the cooling temperature control
loop.
DIS TEMP AI5
{64}
2963
Actual reading from a 10K ohm thermistor connected to the
controller's AI 3 input. When a thermistor is connected at Al 3,
DI 3 is not available.
DIS TEMP MIN
{65}
2963
The minimum value to which DISCH STPT can be set by the
room control loop.
TEMP OFFSET
66
2963, 2965
The room temperature offset is a user-adjustable offset that will
compensate for deviations between ROOM TMP and CTL
TEMP.
HTG P GAIN
67
2963
The proportional gain value for the heating temperature control
loop.
VENT ALM
{68}
2963
Calculates the airflow level that triggers the ventilation alarm.
DISCH STPT
{69}
2963
The discharge temperature setpoint.
AI 3
70
2963, 2965
The biasing of the heating temperature control loop.
SUP P GAIN
71
2963
The proportional gain value for the supply flow control loop.
HTG I GAIN
72
2963
The integral gain value for the heating flow control loop.
PPCL STATE
{73}
2963, 2965
An indicator that customized programming has been added in
addition to the normal control strategy of the application being
used. This point is read as LOADED or EMPTY. A status of
LOADED indicates that there is PPCL programming in the
controller, and it is providing unique control to meet a
customer's job specification. A status of EMPTY indicates that
no unique programming is present.
