Thermostat cannot be added (included) to the Fibaro Z-Wave network.

Safety first: No mains wiring changes are needed.

Steps to resolve inclusion issues:

• 1. Exclude first:
  • Use the Fibaro controller to perform an exclusion on the thermostat, even if it was never included.
• 2. Factory reset:
  • Reset the thermostat to factory defaults following the manual.
• 3. Bring controller close:
  • Perform inclusion with the controller or a portable inclusion device within a few meters of the thermostat.
• 4. Check region/frequency:
  • Ensure the thermostat's Z-Wave frequency matches your controller's region (e.g., EU vs US).
• 5. Clear network capacity:
  • If the controller is near its device limit, remove unused nodes.

When to call a professional: For large networks or persistent inclusion problems, a Fibaro integrator can analyze controller logs and RF conditions.
