Actuator Mounting

Trane offers a factory-mounted actuator with a 90-second

field-installed actuator may be used if desired. Actuator

shaft is ½” diameter and designed to travel clockwise to

close damper and counter-clockwise to open damper.The

indicator on the end of actuator shaft can be used to

determine position of damper.

connected from Flow Rings toTransducer.

2. Connect to controller with Rover™orTU service tool

3. Recalibrate VAV unit

4. Open up VAV damper to Max Flow and measure the

airflow

across the magnahelic.

5. Take the reading and compare it to chart on side of

VRRF

unit to get CFM value.

6. Now that you have the CFM, compare the CFM value of

the

chart on the unit to the FlowValue on the controller

that is shown in Rover orTU on the VAV Status menu.

If they are different adjust the controller to the correct

value.
