Unknown
Device Detected
The thermostat when NOT in conguration mode has detected an unknown device. Typically the
thermostat will send a command to the unknown device and place the device into a soft disable
state. The soft disable control will indicate so as follows:
• On air handler, furnace and outdoor controls, the soft-disabled state is displayed by double
horizontal lines on seven-segment display.
• On the damper control module, the green LED will ash 3 seconds on and 1 second off.
• On the equipment interface module, the green LED will ash 3 seconds on and 1 second off.
• A new communicating device has been added to the system since the original conguration
setup was completed.
• Go to menu > settings > advanced settings > view dealer control center > equipment
and press reset all equipment. This will allow the system to auto-detect any Lennox
communicating devices attached.
Clear alert code by reconguring the
system.

Thermostat did not nd an indoor unit. Make sure there is an Lennox communicating indoor unit
on the system.

• Check R, i+, i- and C connections at mag-mount or subbase, smart hub and all attached
communicating components.
• Ohm wires for electrical continuity.
• Cycle power to both indoor unit rst and then thermostat.
• Verify that equipment interface module (if applicable) is congured as either an air handler or
furnace when used with a non-communicating indoor unit.
• Go to menu > settings > advanced settings > view dealer control center > equipment
and press reset all equipment. This will allow the system to auto-detect any Lennox
communicating components attached.
• Replace indoor unit control if there is no response.
