When routing the temperature probe cables, do not run them in or along the same
conduit as AC-power lines. Follow the guidelines on page 12.
 You can extend probe cables up to 500 feet. For more information, read To

below.
 You can monitor and average the temperatures in four zones. For more
information, read

Replace damaged probes as soon as possible. If there is no probe present or
working properly, the TVS shuts off stage 3 and operates variable stages 1 and 2 at
idle speed.

To extend probe cable
You can extend temperature probe cables to lengths of up to 500 feet. Follow the guidelines below

equivalent. Extension cable is also available from Phason. For more information, contact your
dealer or Phason.
 Join the extension cable to the temperature probe cable as shown in the following diagram.
