Troubleshooting

• Display Blank: Check circuit breaker; ensure power switch at HVAC is on; verify C-wire connection; replace batteries.
  
• Heating/Cooling Not Responding: Set SYSTEM to Heat (temperature > inside temp) or Cool (temperature < inside temp); check for "Wait" (compressor protection); ensure schedule not in energy-saving mode.
  
• Temperature Won't Drop Below Setpoint: System may be in Hold/override; check continuous running due to Auto fan or schedule; manually shut off, then reset.
  
• Fan Not Running: Set to On if in Auto during Off mode.
  
• "Cool On" But No Cooling: Wait 5 minutes for compressor protection; check outdoor temp >50°F.
  
• "Heat On" But No Heat: Verify fuel supply (gas/electric).
  
• Clock/Time Incorrect: Reset using SET CLOCK/DAY.
  
• Low Battery: Replace immediately when warning flashes.
  
• General: Reset by removing batteries for 1 minute if issues persist; contact HVAC contractor, www.trane.com, or 1-800-500-2041.
