Proper sensor placement is critical for accurate temperature readings. Choose an , approximately five feet above floor level, where air circulates freely. Avoid:
Behind doors or in corners where air cannot circulate freely.
Use the and DOWN arrows to set the start time for that period.
The BAYSENS019C is not a simple thermostat; it's a high-voltage, electronically complex component. All installation and service must be performed by a qualified HVAC technician. Attempting to service the unit yourself, especially by bypassing any safety interlocks, could cause serious injury, death, or severe damage to the equipment.

Common causes include high-pressure switch trips, clogged filters, or fan motor failures. Clean any dust accumulation out of the sensor side vents.
To lock or unlock the keypad (if Option 14 is enabled), press and TIME – simultaneously for four seconds.
When first installing the BAYSENS019C, you must configure it to match the physical equipment installed on the roof. Entering the Installer Setup Mode incorrectly can prevent your compressor or heating elements from engaging. Entering Installer Mode:
The BAYSENS019C utilizes the system status LEDs or specific display characters to indicate system faults reported by the Reliatel or Microelectronic board. This comprehensive guide serves as an operator and
: The sensor typically displays current time, temperature, fan status, and overall system status.

Trane BAYSENS019C is a programmable zone sensor designed primarily for commercial HVAC systems, such as Precedent™ Voyager™ Odyssey™
| | Condition | |----------|----------------| | HEAT | Solid = heating mode active; Flashing = heat failure | | COOL | Solid = cooling mode active; Flashing = cool failure | | ON | Colon (:) flashes = system on; Colon steady = system off | | SERVICE | Solid = service required; Flashing = fan failure | | TEST | Unit is in test mode | | CHECK FILTER | Accumulated runtime exceeds the interval set in Option 12; press ERASE to reset |
: The main ReliaTel or Voyager control board has detected a system failure (such as a dirty filter switch, fan failure, or compressor lockout). Check the diagnostic LEDs on the main unit control board.
