Defective or loose module
Replace module in zone 1-4 position
- Try a different module. You could have a defective module.
- Modules must be installed from left to right with no open module positions in between modules.
- AC must be present before the controller will recognize newly added modules. Make sure the panel is tightly closed and the 9V battery is not connected and try again.
- If none of the above works, try a Total Reset of the controller as explained in section 7.1 of your manual.
