Frame
The fifth byte selects a particular zone that is to respond to this message. Each of
four bits represents a zone; thus, four zones are defined. Zones can be individually
addressed or in any combination.
Reserved
ZONE<3:0>: Zone Select
0000 = No zones
0001 = Zone 1
0010 = Zone 2
0011 = Zone 1 and 2
0100 = Zone 3
0101 = Zone 1 and 3
0110 = Zone 2 and 3
0111 = Zone 1, 2 and 3
1000 = Zone 4
1001 = Zone 4 and 1
1010 = Zone 4 ad 2
1011 = Zone 4, 1 and 2
1100 = Zone 4 and 3
