Point Name – Description Default/Range
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’ 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.

System Cool Demand Level – The system cool demand level being received over the network.
D: 0.00
R: 0 to 3
System Leaving Water Temperature – Allows using another controller's leaving water temperature sensor
value (system water temperature), to be read over the network. The remote controller must have a network-
accessible leaving water temperature sensor value.
D: -999°F
R: -25 to 125°F
System Entering Water Temperature – Allows using another controller's entering water temperature
sensor value (system water temperature), to be read over the network. The remote controller must have a
network-accessible entering water temperature sensor value.
D: -999°F
R: -25 to 125°F
System Outdoor Air Temperature – Allows using another controller's outdoor air temperature value over
the network. The remote controller must have a network accessible outdoor air temperature sensor value.
D: -999°F
R: -50 to 150°F
System Control Setpoint – Allows using another controller's Control Setpoint value to be read over the
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

indicated by the controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Ent Water Temp Alarm – When set to Enable, any Entering Water Temperature Alarm indicated by the
controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Ent Wtr Sensor Fail Alarm – When set to Enable, any Entering Water Temperature Sensor Failure Alarm
indicated by the controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Outdoor Air Temp Alarm – When set to Enable, any Outdoor Air Temperature Alarm indicated by the
controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Outdoor Air Sensor Fail Alarm – When set to Enable, an Outdoor Air Temperature Sensor Failure Alarm
indicated by the controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Fan VFD Fail Alarm – When set to Enable, a Fan VFD Failure Alarm indicated by the controller also initiates
an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Lvg Water Temp Hi Alarm – When set to Enable, a High Leaving Water Temperature Alarm indicated by
the controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Negative DeltaT Alarm – When set to Enable, a Negative Differential Temperature Alarm indicated by the
controller also initiates an Equipment Alarm and energizes the Alarm Lamp binary output.
D: Enable
R: Disable/Enable
Service Test
Service Test – When set to Enable, any output can be overridden for up to 5 minutes. The Service Test has
a 1 hour timeout.
D: Disable
