The Aube TH135-01 is a digital non-programmable thermostat designed for line-voltage electric baseboard and radiant heating systems. It offers simple temperature control, a clear display, and reliable performance for homes using 120 to 240 V circuits. This article explains its key features, technical specifications, installation steps, and common troubleshooting tips to help homeowners and installers optimize comfort and energy use without complex programming.
Overview Of The Aube TH135-01
The TH135-01 is a compact, wall-mounted thermostat that handles high-voltage heating elements directly. Its non-programmable interface makes it ideal for rooms where simple on/off control and steady temperature are preferred. The device is compatible with most baseboard and electric radiant systems and is known for straightforward wiring and dependable operation.
Because it operates on line voltage, the TH135-01 eliminates the need for an external relay or low-voltage control wiring. This reduces components and simplifies installation in many residential setups. The absence of programming features means users adjust the temperature manually to meet daily comfort needs.

- Control Type: Non-programmable, manual temperature adjustment
- Mounting: Wall-mounted with standard single-gang enclosure compatibility
- Thermostat Type: Line-voltage, direct-control thermostat for electric heating elements
Installation And Wiring Considerations
The TH135-01 installation involves wiring directly to the heating element circuit. Before starting, turn off power at the main panel and verify absence of voltage. Always follow local electrical codes and, if unsure, consult a licensed electrician.
- Wiring Configuration: Connect incoming hot and neutral lines to the thermostat per the manufacturer’s wiring diagram. Some baseboard setups may require a single-pole connection; others use a two-pole configuration. Do not connect to low-voltage circuits.
- Grounding: Ensure proper grounding as required by code and the thermostat’s instructions.
- Load Compatibility: Verify the heating element amperage and the thermostat’s rated load. Exceeding specifications can cause overheating or failure.
- Enclosure And Accessibility: Install in a suitable electrical box or enclosure with sufficient depth for wiring and easy access for future adjustments.
Programming And Temperature Control
As a non-programmable model, the TH135-01 relies on manual temperature adjustment. Users should set a stable temperature that aligns with comfort and energy goals. For consistent climate zones, place the thermostat in an area representative of the room’s average temperature and away from drafts, direct sunlight, or heat-producing appliances to avoid skewed readings.
- Setting Temperature: Use the up/down controls to select the desired room temperature. Allow time for the system to reach and stabilize at the new setting.
- Energy Considerations: Maintain a steady comfort level rather than frequently changing temperatures to maximize efficiency with line-voltage heating systems.
- Maintenance: Periodically check wiring connections for signs of looseness or corrosion and inspect the thermostat for dirt or firmware-related display issues if applicable.
Troubleshooting And Common Issues
- No Heat Output: Confirm power to the thermostat and verify that the heating element is functional. Check wiring continuity and ensure the thermostat is set to a temperature higher than the current room temperature.
- Thermostat Not Reading Correctly: If the display seems erratic, examine for loose connections, replace batteries if applicable, and ensure the unit is mounted at the correct height and away from heat sources.
- Stuck On Or Off: Inspect the internal switch mechanism and wiring for faults. If the device shows continuous heat or fails to trigger, replacement may be necessary.
- Display Dim Or Inactive: Check the power supply and look for signs of damage to the LCD. Replace unit if illumination is severely degraded.
Compatibility And Safety Considerations
The TH135-01 is designed for line-voltage heating systems, including baseboard and electric radiant heaters. It should be used only with compatible loads and within electrical code guidelines. When integrating with multi-zone setups or retrofits, confirm total load calculations and ensure each thermostat controls a dedicated circuit to prevent overloading a single line.
For safety, never bypass electrical safety features or expose the thermostat to moisture, which can compromise performance and create electrical hazards. Use only approved wiring methods and enclosure types as specified by the manufacturer and local regulations.
