I/O Modules Expansion Modules & Wiring Adapter
Introduction
The I/O modules are advanced expansion devices designed to integrate with a variety of Honeywell controllers. These are available in 17 models to cover all your application requirements.
The I/O modules can co-exist with the legacy Panel Bus™ I/O module on the same bus, thereby eliminating the need to replace all legacy Panel Bus™ I/O modules in the panel.
The I/O modules connect directly to the controller using touch flake connections, which provide the power and communication bus. The Wiring Adapter also provides power and communications, typically used to extend the power and communication bus to an additional row of I/O modules or to a remote panel. The Wiring Adapter can be powered with the same or a separate power supply as the controller. The I/O modules are programmable using the Optimizer Workbench, Comfort & Energy Workbench, or ComfortPoint Open Studio Tool. Software updates, configuration, and commissioning are done automatically by the controller.

Service Button
The I/O module has a physical service button to reset the device to factory default. This is the recommended method, often achievable while keeping power on.
With Power On (Recommended method): Press and hold the service button for 10-15 seconds until the service LED blinks Green, then release the button and short press the service button within 5 seconds to confirm the reset.
With Power Off (Alternative method): Press and hold the service button, then turn power on to the I/O module. Continue holding the service button for 10-15 seconds until the service LED blinks Green, then release and short press to confirm the reset.
The reset performs the following operations:
- Resets the local I/O configuration.
- Keeps the current firmware version.
- Erases historical data.
