Field Configuration
The following configurations must be set in the 09FC controls per
the site application for proper operation.
LEAVING WATER SETPOINT
OUTDOOR AIR SETPOINT
The Table 14 below is a reference for the major points in the con-
trol. For a detailed list see appendix B.
Table 14 — Field Configuration
POINT NAME DESCRIPTION DEFAULT/RANGE
Cool Enable Enables or disables cooling operation. D: Enable
R: Disable/Enable
Leaving Water Temp Setpoint The leaving water temperature setpoint maintained by the module. D: 44°F
R: 15 to 75°F
Outdoor Air Temp Setpoint The outside air temperature below which the module is allowed to operate. D: 50°F
R: –20 to 80°F
OAT Offset Setpoint The number of degrees that the outdoor air temperature must rise above set-
po
int to disable the module’s operation.
D: 3°F
R: 1 to 10°F
Remote Contact Normal Logic
State
Specifies the remote contact’s normal logic state. D: Open
R: Open/Closed
Fan VFD Run Status Normal Logic
State
Specifies the fan’s variable frequency drive run status normal logic state. D: Open
R: Open/Closed
Fan VFD Output Type Defines the type of fan variable frequency drive output control. D: 0-10V
R: 0-10V/2-10V
Fan Initial Start Speed The speed that the module’s fans are briefly run on initial startup. D: 100%
R: 0 to 100%
Fan Minimum Speed The lowest speed that the module’s fan is commanded when the fans’ vari-
able frequency drive is enabled.
D: 20%
R: 0 to 100%
Fan Speed PID The BACnet Object calculates the amount of fan speed required to satisfy the
Leaving Water Temp Setpoint and allows access to the control loops tuning
parameters.
NOTE: The following default values should be charged only by a technician
trained in tuning PID loop algorithms.
Action direct
Update Interval 1:00 mm:ss
Proportional 15
Integral 5
Derivative 0
Deadband 0
Bias 0
R: 0 to 100%
Bypass Valve PID This BACnet Object calculates the amount of bypass required to satisfy the
Leaving Water Temp Setpoint when bypass valve modulation is enabled and
al
lows access to the control loop’s tuning parameter.
NOTE: The following default values should be changed only by a technician
trained in turning PID Loop algorithms.
Action reverse
Update Interval 1:00 mm:ss
Proportional 10
Integral 2
Derivative 0
Deadband 0
Bias 0
R: 0 to 100%
Lvg Wtr Temp Setpoint OA Reset En
ables OA reset of the leaving water temperature’s setpoint. D: Disable
R: Disable/Enable
Maximum LWT Setpoint OA Reset The highest leaving water temperature setpoint reset allowed by the outdoor
air temperature.
D:
10°F
R: 0 to 25°F
