A technician cannot configure Johnson Controls (JCI) packaged rooftop units (RTUs) because the supplied NS8000 thermostats are not triggering heating or cooling, likely due to deadband or occupancy settings, and the mobile app fails to connect via Bluetooth to the units.
The app cannot reliably connect to the units via Bluetooth, preventing on-site configuration changes. Additionally, the thermostats may require manual parameter adjustments (deadband, occupancy) that are not accessible through the basic thermostat interface.
Workarounds Described
- tries to use JCI Comm board app via Bluetooth but fails to connect
- searches online forums for manual configuration steps
Implied Software Gaps
- Reliable mobile app for direct Bluetooth connection to JCI unit controllers
- Commissioning tool that can read and write all unit parameters (deadband, occupancy) without laptop
HVAC Commissioning Assistant
A mobile app that provides seamless, reliable Bluetooth or Wi-Fi connectivity to HVAC equipment for on-site commissioning. It auto-detects units, downloads configuration profiles, and allows technicians to adjust critical parameters like deadband, occupancy, and setpoints without needing a laptop or proprietary software. It logs changes and can sync to the cloud for documentation.
- Reliable Bluetooth/Wi-Fi connection with auto-retry and error recovery
- Graphical interface to view and edit all controller parameters (deadband, occupancy, setpoints)
- Pre-loaded configuration templates for common unit types (JCI, Greenheck, etc.)
- Change log and report generation for commissioning documentation
