Fan Control: Includes On (continuous) and Auto (cycles with heat/cool) modes. Temperature Ranges: Cooling: 45°F to 98°F. Heating: 43°F to 96°F.

Memory: Retains programming in permanent memory during power interruptions, though the clock may need resetting after long outages. Installation & Troubleshooting

The BAYSENS019C is a communicating sensor that uses DC voltage (typically 24–32 Vdc). This distinguishes it from standard 24VAC thermostats.

Wiring: It typically uses a numbered terminal configuration (e.g., terminals 1 to 1, 2 to 2) rather than standard lettered terminals (R, W, Y, G).

Mounting: Install on an interior wall approximately five feet above the floor, away from direct sunlight or drafts.

Compatibility Note: Because it operates on DC communication, it is not directly interchangeable with standard aftermarket thermostats like Honeywell unless a Conventional Thermostat Interface (CTI) board is installed in the HVAC unit.

Testing: To verify a sensor is working, check the DC voltage across terminals 11 and 12; it should read between 28 to 32 Vdc when disconnected and flash at a 0.5-second rate when connected.

For detailed technical guidance, you can refer to the BAYSENS019 Installer's Guide or the BAYSENS119 Troubleshooting Guide, which often covers similar programmable models.

The Trane BAYSENS019C is a remote room sensor used with Trane commercial heating and cooling units. It allows you to monitor and control indoor temperatures from a distance, typically working in conjunction with a central Voyager or Precedent rooftop unit. Quick Setup & Functionality

Purpose: It acts as a thermistor-based sensor that communicates the local temperature back to the unit controller.

User Controls: Most versions of the 019C series feature a Cancel/Timed Override button and a Status LED to show if the system is running or if there is a "service" required.

Temperature Adjustment: Depending on the specific configuration, it may have a thumbwheel for local setpoint adjustment (typically +/- 3 degrees or a specific range like 50–90°F). Wiring & Terminal Connections

To install or troubleshoot the sensor, the following terminal connections are standard: Terminal 1: Ground / Common. Terminal 2: Temperature Sensor Signal.

Terminal 3: Setpoint Potentiometer (used to communicate the desired temp).

Terminal 4: LED / Status Signal (usually for the "Service" or "Filter" light).

Terminal 5: Override Button (sends a signal to the controller to switch from Unoccupied to Occupied mode). Troubleshooting Tips

"Service" Light Is On: This usually indicates a fault at the main HVAC unit (like a tripped high-pressure switch or a dirty filter) rather than a problem with the sensor itself.

Inaccurate Readings: Check for drafts behind the sensor. If the hole in the wall where the wires come through isn't sealed, air from the wall cavity can skew the temperature reading.

Sensor Failure: You can test the sensor with an ohmmeter. At 25°C (77°F), the resistance should be approximately 10k Ohms. Manual Resources

Because Trane equipment is often proprietary, the most detailed instructions are found in the Trane Voyager or Precedent Installation Manuals. You can search for Trane document ACC-SVN02A-EN (Sensor Installation Guide) or RT-SVN04G-EN (Programming Guide) for specific resistance charts and wiring diagrams.
