reads the settings of these configuration jumpers at
startup. After 200 hours of main valve operation, the relay
module locks the jumper settings into internal memory. If
these jumpers are changed after the 200 hours occur, the
relay module locks out. This safety function assures that
the relay module cannot be modified after it is installed in
a particular location.
If JR3 (Airflow Switch) is intact (no Airflow Switch), then a
jumper must be installed between terminals 6 and 7. If
JR3 is clipped (Airflow Switch is present), the relay module
locks out if it detects a jumper between terminals 6 and 7.
