Controller Wiring
Notes: 1. The Digital (triac) Outputs are isolated from all other internal
circuits.
2. The 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.
