Notifications (Alert Codes)

These screens provide information on active notifications and previously cleared 

notifications. When selecting either a cleared or active notification a brief description 

and alert code will be displayed. Notifications are categorized by system, indoor 

unit (air handler or furnace), outdoor unit (air conditioner or heat pump), zoning 

control (if installed) and thermostat.

To expand a specification notification to access a more detail description of the 

alert code, press the down arrow to expand the description.

•  Critical alerts are displayed on Home (user) screen, in the Homeowner alert 

button, and in the Installer alert button. Critical means that a service call is 

needed to get the system running.

•  Minor and Moderate alerts are found only in the Installer alert button.
What does minor and moderate mean?
•  Minor is information only, helps Lennox interpret test results, understand 

complicated behavior.

•  Moderate means that the system will likely recover on its own, no action 

necessary.

Communication System: When communication controls are operating in a 

communication system, all jumper and link setting on controls are ignored. Jumpers 

and link setting are treated as defaults and would only be active if the system was 

converted to a non-communicating system.
