The Aube TH135-01 is a digital non-programmable thermostat designed for line-voltage electric heating systems. This compact, reliable device focuses on simple, accurate temperature control without the complexity of programmable schedules. It is widely used in residential and light commercial settings to maintain comfort while delivering straightforward installation and operation. This article covers the TH135-01’s key features, compatibility, installation steps, troubleshooting tips, and practical use cases, emphasizing terms and considerations relevant to American HVAC setups.
Overview And Key Benefits
The TH135-01 operates as a basic temperature-regulating device for 240-volt heating systems, typically connected to baseboard, electric radiators, or other electric zone heating components. Its major advantages include:
- Simple User Interface: A clear digital display and a single control knob or button allow quick and precise adjustment without programming.
- Accurate Temperature Control: The device provides stable setpoint temperatures, reducing temperature swings and improving occupant comfort.
- Reliability: Built for line-voltage environments, it resists interference and is durable under typical American household electrical conditions.
- Compatiblity With Line-Voltage Systems: Specifically designed for 120/240 V circuits used in baseboard and resistance heating, making it a practical replacement for older mechanical thermostats.
Because it is non-programmable, the TH135-01 excels in scenarios where a fixed temperature setting is sufficient and ease of use is prioritized over scheduling capabilities. It is important to verify the thermostat’s voltage range and load compatibility to ensure proper operation and safety.

Installation And Wiring Guidelines
Proper installation ensures accurate temperature control and electrical safety. The TH135-01 is generally installed by a licensed electrician or a skilled HVAC technician following local electrical codes. Key steps include:
- Power Off: Shut off power at the circuit breaker to prevent shock during wiring.
- Remove Existing Thermostat: Take off the faceplate and detach wires carefully, noting each connection.
- Identify Wire Functions: Typical connections include line (hot) wires and heat call wires. Some setups use a jumper or specific terminals as indicated by the manufacturer’s wiring diagram.
- Connect To TH135-01: Attach wires to the corresponding terminals on the thermostat base. Ensure tight, secure connections to prevent arcing or loose contact.
- Mount And Test: Secure the thermostat to the wall, restore power, and verify display and setpoint function. Adjust temperature to confirm the heating element responds correctly.
Note: Some installations may require a C-wire or common wire in certain setups, but line-voltage models like the TH135-01 typically operate without a low-voltage transformer. Always refer to the included manual for exact terminal designations and wiring diagrams specific to the TH135-01 version you purchase.
Wiring Diagrams And Compatibility
Understanding compatibility is crucial for safe operation. The TH135-01 is designed for line-voltage heating systems and is not suitable for low-voltage (24 V) or smart heating configurations without appropriate adapters or intermediate relays. Before purchasing or replacing a thermostat, verify:
- Voltage Alignment: Confirm the system uses 120/240 VAC, not 24 VAC or battery-powered controls.
- Load Assessment: Ensure the heater load falls within the thermostat’s rated amperage, preventing overheating or switch failure.
- Wiring Path: Confirm that the wiring path from the breaker to the heating element is uninterrupted and that the thermostat can handle the circuit’s current draw.
If uncertain, consult the TH135-01’s official wiring diagram and consult with a licensed electrician to avoid electrical hazards.
Operation Best Practices
To maximize comfort and energy efficiency with the TH135-01, consider these practices:
- Proper Setpoint: Choose a comfortable, energy-conscious temperature and avoid frequent manual adjustments. A fixed setting reduces cycling and wear on the heating system.
- Location Considerations: Install the thermostat away from direct sunlight, drafts from windows or doors, and heat-producing appliances to prevent false readings.
- Maintenance: Periodically inspect wiring connections for signs of wear or looseness and ensure the display remains legible.
- System Compatibility Check: If the existing heating system includes zone controls or thermostatic radiators, ensure the TH135-01 integrates correctly with the overall control strategy.
For specific energy-saving strategies in homes with electric baseboard heating, consider pairing non-programmable thermostats with lifestyle-based usage patterns, such as turning down heat during unoccupied hours and using ceiling or space heaters only as needed for comfort in occupied rooms.
Troubleshooting Common Issues
Common issues with the TH135-01 can generally be addressed through methodical checks. The following quick-reference guide covers typical symptoms and remedies:
- Thermostat Not Powering On: Confirm line power at the circuit breaker and verify that wiring connections are secure. Replace any blown fuses or tripped breakers.
- Display Blank Or Incorrect Readings: Check for loose wires, faulty terminals, or damaged display components. If necessary, replace the thermostat.
- Heater Not Responding: Ensure the thermostat is properly set to a temperature above the room temperature. Inspect the heater element and circuit for continuity and safety.
- Inaccurate Temperature: Calibrate or adjust the setpoint within the thermostat’s range. Check for drafts or external heat sources skewing readings.
- Intermittent Operation: Inspect wiring for loose connections and ensure the thermostat is firmly mounted to avoid movement.
If problems persist, consult the product manual or contact the manufacturer’s support line for model-specific advice and warranty considerations.
Maintenance And Longevity
Routine maintenance helps extend the life of a TH135-01 installation. Consider these steps:
- Regular Visual Inspections: Look for signs of wear, corrosion on terminals, or frayed wiring.
- Clean Installation Area: Keep the thermostat clear of dust and debris that could affect airflow around internal components if applicable.
- Professional Checkups: Schedule periodic checks with a licensed electrician, particularly after major electrical work or building renovations.
With proper care, the TH135-01 can provide reliable, straightforward temperature control in electric heating systems for many years.
