Connecting an
airflow sensor
An airflow sensor is incorporated as one of the inputs to the controller. Remove
the plugs and connect the tubing from the pitot assembly to the airflow sensor
inputs next to the drive hub. (See Illustration 2-14). The airflow sensor is
programmed as Input 1.
Connecting
power
The controllers require an external, 24 volt, AC power source. Use the following
guidelines when choosing and wiring transformers.
Do not run 24 volt, AC power from within an enclosure to external
controllers.

Use a Class-2 transformer of the appropriate size to supply power to
the controllers. Titus recommends powering only one controller from each
transformer.
