Correlation groups programming
A correlation group is a collection of inputs and outputs (input
devices, output devices, NACs, and zones). Correlation groups link
input devices to output devices. The input devices in the correlation
group are associated with the output devices in the correlation
group. Activation of an input device in the correlation group turns on
every output device in the correlation group. For example, if you
assign a zone with five input devices and five output devices to
Group 1, whenever one of the input devices activates in Group 1, all
five output devices in Group 1 turn on.

A correlation group can contain any combination of input devices,
output devices, NACs, and zones. Input devices, output devices,
NACs, and zones can be assigned to more than one correlation
group. There are 32 available correlation groups.
