How to check the existing piping settings
You can check whether the existing piping settings are enabled.
1. Check that the LED displays are placed in their initial status. If not, place them in the initial status.
2. Hold down SW01 for at least 5 seconds, and check that D804 flashes slowly. (Fig. 9)
3. Press SW01 four times to set the LED displays (D800 to D805) to the "LED displays for existing piping settings"
shown below. If the setting is enabled, D802 lights and D804 and D805 flash rapidly. (Fig. 10)
4. Hold down SW01 and SW02 simultaneously for at least 5 seconds to return the LED displays to the initial status.

When restoring the factory defaults
To restore the factory defaults in situations such as when relocating the units, follow the steps below.
1. Check that the LED displays are placed in their initial status. If not, place them in the initial status.
2. Hold down SW01 for at least 5 seconds, and check that D804 flashes slowly. (Fig. 11)
3. Press SW01 14 times to set the LED displays (D800 to D805) to the "LED displays restored to factory defaults"
shown below. (Fig. 12)
