1.Field selectable external output options (all possible options are shown).

2.This is the condensing unit on/off signal on split-systems.

3.Field selectable external input options (all possible options are shown).

4.DX pressures switch not installed on split-systems; this input is then wired for constant no-fault condition.

5.Not installed or wired on split-systems.

6.Optional.
