A350R, can I switch the warm weather shut down setting when the controller is powered up?

Johnson Controls System 350 Reset Controller warm weather shutdown

We recommend powering down the controller when changing jumper settings.

The jumper block on the base mounted circuit board is used to select warm weather shutdown setpoint. Setpoints available are Off, 60°F, 64°F, 68°F, and 72°F. If any other setpoints are desired, use a separate controller like the A19
