Code Sets, Zone IDs, and Logical Zones
NOTE: The terms Code Set, Zone ID, and Logical Zone are synonymous.
The terms Code Set, Zone ID, and Logical Zones are synonymous, however various contexts
typically use a specific terminology.
NOTE: Code Sets, Zone IDs, and Logical Zones are referred to by number. For example,
there are 9 default Code Sets / Zone IDs / Logical Zones configured in a CT 610. The
default Code Sets are as follows: 0, 3, 4, 11, 12, 13, 14, 15, and 16.
Code Sets
As in earlier B&K Components devices there are system parameters to allow command and
control of individual Zones (ZA and ZB, previously Z1 and Z2). The term Code Set is primarily
used in conjunction with command and control of a device via RS-232, Infra Red remotes and
keypads. A Code Set is essentially a product ID associated with an IR remote or keypad. A single
Code Set may be assigned to control a single Hardware Zone Group or a Grouping of Zones (see
Groups above). This implies that multiple remotes and keypads may uniquely control the same
Hardware Zone.
NOTE: Code Sets are referred to by number. For example, there are 9 default Code Sets in
the CT 610:
One Whole House Code Set: 0
Two Code Sets assigned to control multiple Hardware Zones: 3 and 4
Six Code Sets assigned to control individual Hardware Zones: 11, 12, 13, 14,
15, and 16
Zone IDs
The term Zone ID is used basically in the same context as a Code Set. However, Zone ID is not
commonly associated with Infra Red remotes and keypads, but thought of as purely a mechanism
to assign Logical Zones to Hardware Zones.
The importance of the term Zone ID has lessened, and it is typically referred to as a Code Set.
Recall, a single Code Set may be assigned to control a single Hardware Zone or a Grouping of
Zones. This implies that multiple remotes may uniquely control the same Hardware Zone.
