The Lightstat TME has a visual alarm to indicate that there is a problem with the
Roof Top Unit (RTU). This is a eld option. You might not have this option with
your specic RTU.
Use #18 gauge 2-conductor cable between the Lightstat TME and the RTU. The
alarm is unaffected by wire runs of up to 1000 feet.
If the alert does not function correctly, verify proper installation of wiring
and jumper.
