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’ variable

frequency drive is enabled.

D: 20%

R: 0 to 100%

Fan Speed PID

– This BACnet Object calculates the amount of fan speed required to satisfy the

Leaving

Water Temp Setpoint

and allows access to the control loop's tuning parameters.

NOTE

: The following default values should be changed only by a technician trained in tuning PI

D Loop algorithms.

network. The remote controller must have a network-accessible point.

D: -999°F

R: -20 to 65°F

System Occupancy

– Allows reading and using another controller's occupancy status value over the

network. The remote controller must have a network-accessible Occupancy Status point.

D: Unoccupied

R: Unoccupied/Occupied
