---- / 1 Depending on the device, the default is "----" (e.g. RMU7x0B) or "1" (e.g. RMU7x0).
See also section 7.1.4 for information on the default "----" with the series B devices.
---- With RXB/RXL room controllers "----" indicates that the zone is "out of service" and there are no
process values transmitted from this zone (in the QAX34.3 room device, "-1" is displayed
instead of "----".
* The zone address range for the RXB/RXL room controllers is 0…63 or 0…15.
