Point Name/Description
Flow Measurement Units – The flow measurement output. Do not change the
default of cfm (liters/second).
Damper Motor Travel Time – The actuator's travel time from full closed to full
open. Leave this field at 205 seconds.
Direction Clockwise – If Damper Actuator is set to Built-in actuator, set this field
to the damper's position when it rotates clockwise.
Target Damper Position - The current damper position. To override normal
control for troubleshooting purposes, select Lock value to and then enter a value.
The damper moves to that position until Lock value to checkbox is cleared.
Auxheat - The current configured Reheat Min Damper Position. To override
normal control for reheat troubleshooting purposes, select Lock value to and then
enter a value. The damper moves to that position until Lock value to checkbox is
cleared.
Fan – The current value of the fan output relay. To override normal control for
troubleshooting purposes, select Lock value to and then enter On or Off. The relay
stays in that state until the Lock value to checkbox is cleared.
Cooling Max Airflow – The maximum airflow the terminal will supply when trying
to meet a zone cooling demand when the air source mode is Cooling, Vent, or
Free Cooling.
Heating Max Airflow – The maximum airflow the terminal will supply when trying
to meet a zone heating demand when the air source mode is Heating or Warm-up
and VAV heating has been enabled.
Occupied Min Airflow – The minimum airflow setpoint the terminal controls to
when the air source is operating and the terminal mode is occupied.
Unoccupied Min Airflow – The minimum airflow setpoint the terminal controls to
when the air source is operating and the terminal mode is unoccupied.
Auxiliary Heat Min Airflow – ONLY used for Single Duct units with ducted reheat.
Set to the minimum airflow specified by the manufacturer to allow the reheat to
provide optimum performance. This value is compared to the appropriate Min
Airflow value above and the greater of the two values determines the damper
position. For all other terminal types, set to 0.
Manufacturer's specified airflow at 1" water column – The damper
manufacturer's rated cfm airflow at 1" water column of velocity pressure. Refer to
the manufacturer's documentation to obtain the correct value.
Use supply air for heating when Heat Mode is ON — This must be checked for all
applications. To only use the minimum airflow in heating, set Service
Configuration > VAV Heating to Disable.
