    Checking Guide Vane Linkage — When the chiller
    is off, the guide vanes are closed and the actuator mechanism is
    in the position shown in Fig. 37. If slack develops in the drive
    chain, do the following to eliminate backlash:
    1. With the chiller shut down and the actuator fully closed,
    remove the chain guard and loosen the actuator bracket
    hold-down bolts.
    2. Loosen guide vane sprocket adjusting bolts.
    3. Pry bracket upwards to remove slack, then retighten the
    bracket hold-down bolts.
    4. Retighten the guide vane sprocket adjusting bolts. Ensure
    that the guide vane shaft is rotated fully in the clockwise
    direction in order close it fully.

    Go into the controls test, scroll down to guide vane calibration and push select. If it fails more than likely it is the vane potentiometer.

    Yep. I had a vane pot on one of my 19XR chillers develop a "flat spot" and send back erroneous info to the PIC. A new pot solved that problem.

    Building Physics Rule #2:
    Higher air pressure moves toward lower air pressure


    Building Physics Rule #3:
    Higher moisture concentration moves toward lower moisture concentration.
