DESCRIPTION
Enables or disables cooling operation.
The leaving water temperature setpoint maintained by the module.
The outside air temperature below which the module is allowed to operate.
The number of degrees that the outdoor air temperature must rise above set-
point to disable the module's operation.
Specifies the remote contact's normal logic state.
Specifies the fan's variable frequency drive run status normal logic state.
Defines the type of fan variable frequency drive output control.
The speed that the module's fans are briefly run on initial startup.
The lowest speed that the module's fan is commanded when the fans' vari-
able frequency drive is enabled.
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.

Leaving Water Temp Setpoint when bypass valve modulation is enabled and
allows access to the control loop's tuning parameter.
