When these outputs are configured as Analog, PWM or floating outputs, the corresponding output
control parameters can be configured.
Analog Control: This option enables you to enter analog output mode and analog output control for
damper motor.
PWM Control: This option enables you to enter Pulse Width Modulation (PWM) period, zero scale
and full scale.
Floating Control: This option enables you to enter floating motor travel time, startup sync position,
startup delay, auto sync position and auto sync interval.
'Unocc sync Position' can be used to configure whether the floating output should be synchronized
when effective occupancy transitions to 'Unoccupied'.
'Network sync Position' can be used to configure whether the floating output should be synchronized
on an active nviFree1Dig signal.
Note on configuring reverse action for outputs:
Analog: Use the 'Analog Output control' field to configure the output ranges that map to 0-100%.
PWM: To get reverse acting PWM, configure PWM zero scale with a higher value compared to PWM
Full scale.
Floating: Use the 'Action' field to change direction of control. Alternately, the pins assigned to 'Open'
and 'Close' can be swapped in the custom wiring screen to reverse the action.
Modulate Reheat
Flow
Enables you to configure whether airflow and damper should be controlled (between minimum position
and fixed reheat position) according to the temperature control loop.
Peripheral minimum
position
This feature can be used to maintain flow in pipes that may otherwise freeze. If the outdoor air
temperature value is connected to the zone terminal, the minimum position is active when the outdoor
air temperature is below 40F.
Heating Sequence When both reheat and peripheral heat are configured, this allows you to specify the sequence in which
these outputs are controlled.
