instance number = 100001.
Lock Function Setup and Examples
The 16-bit binary encoded decimal register accessed through Lock [AV17] BACnet
object and LOC engineering menu item is used to enable/disable features in the
thermostat. The first 10 bits are used (bit 0 ~ bit 9), bits 10~15 are reserved/unused.
Bits are represented by their decimal values and are added or subtracted to toggle
from "0" to "1". Add a bit's decimal value to toggle to "1" or subtract a bit's decimal
value to toggle to "0". See table below.
