Controller Wiring
Notes: 1. The Digital (triac) Outputs are isolated from all other internal circuits.
2.
The Analog Outputs and Digital Inputs have the same “common” as the 24 VAC
Power Supply.
3.
The Analog Input “common” is the same as the internal logic circuit common, but is
isolated from the 24 VAC Power Common.
4.
The System 91 N2 Communications Bus is isolated from all other internal circuits.
