Compared with basic non-programmable thermostats, the TH115 Series offers better scheduling, better energy management, and more precise temperature control. Against Wi-Fi smart thermostats, it trades app-based control for greater simplicity and lower installation complexity, which is often a better fit for dedicated electric heating systems.

How to Set Up the TH115 Series Thermostat: Step-by-Step Installation Guide

Before installation, turn off power at the breaker and verify the circuit is de-energized. Remove the thermostat faceplate from the wallplate, then mount the wallplate securely to the electrical box. Connect the load and power supply wires according to the model diagram, and connect the floor sensor if your version supports radiant floor control. Reinstall the faceplate, restore power, and then configure the internal switches for the correct mode, display format, and early-start settings if available.

Next, set the clock and program the schedule. Most TH115 models let you program comfort and economy periods for each day, or copy settings across multiple days for quicker setup. For radiant floor systems, choose the correct sensor mode to avoid overheating the floor. If the thermostat does not power up, recheck wiring, breaker status, and load compatibility. If the display shows unusual readings, confirm that the sensor is properly connected and that the system is set to the right control mode.

Safety warning: The TH115 Series is a hardwired line-voltage thermostat. Installation should be performed only by a qualified person if local electrical codes require it. Do not exceed the thermostat’s rated current or load capacity.

Troubleshooting the aube technologies TH115 Series Programmable Thermostat

If the thermostat is not heating, start with the basics: confirm that power is on, the breaker has not tripped, and the setpoint is above room temperature. If the floor is not warming on a radiant system, check the floor sensor connection and verify the thermostat is in the correct floor or ambient-plus-floor mode. If the screen is blank, inspect line-voltage wiring, breaker condition, and any disconnected lead.

Problem: No heat output. Fix: Raise the setpoint, verify wiring, and confirm the heater itself is functional.
Problem: Incorrect temperature reading. Fix: Ensure the sensor is installed correctly and not pinched or damaged.
Problem: Frequent tripping on protected models. Fix: Check for moisture, wiring faults, or a heater issue before resetting.
Problem: Programming lost or schedule ignored. Fix: Review time, day, and mode settings after power interruptions.

Most TH115 thermostats do not use complex error-code systems, so troubleshooting usually involves checking wiring, sensor input, load size, and configuration switches. Preventive measures include using the correct thermostat model for the heating type, avoiding load overload, and inspecting terminal connections during seasonal maintenance. Warranty terms vary by seller, but support is typically available through the manufacturer, distributor, or electrical supplier. Keep your model number and installation details ready when requesting help.

Faqs

How do I set up the aube technologies TH115 Series Programmable Thermostat for the first time?

Start by turning off power at the main panel, then remove the thermostat faceplate and wire the unit according to your heating system type. After mounting the wallplate, set the configuration switches before reinstalling the faceplate and restoring power. Once powered, set the day, hour, and minute, then choose Manual or Automatic mode. For the best first-time setup, confirm whether your model is in A, F, or AF mode so the thermostat matches your floor or ambient heating system.

What does the A, F, and AF mode mean on the aube technologies TH115 Series Programmable Thermostat?

The TH115 Series uses three control modes to match different heating setups. A mode controls ambient air temperature only, which is useful for standard room heating. F mode controls floor temperature with an external sensor, making it ideal for radiant floor systems. AF mode controls room temperature while also keeping the floor within set limits, giving you comfort and protection from overheating. Choosing the right mode is important for performance, safety, and accurate temperature control.

How do I program the aube technologies TH115 Series Programmable Thermostat for different days of the week?

Use the PGM button to step through each program period, then set the day, hour, and minute for each schedule entry. You can program up to four periods per day, which gives you flexibility for morning, daytime, evening, and night temperatures. If you want the same schedule all week, hold the Day button for a few seconds to apply settings to all seven days. This makes the TH115 Series ideal for saving energy while keeping a predictable comfort routine.

Why is my aube technologies TH115 Series Programmable Thermostat not heating even though the display is on?

If the display is active but the system is not heating, check whether the thermostat is in Standby or Manual mode and verify that the set temperature is higher than the current room temperature. Also confirm that the heating system has power, wiring is secure, and the thermostat is configured for the correct mode and voltage. If your model uses a floor sensor, make sure the sensor is connected properly. A mismatch in configuration is a common cause of no-heat problems.

How do I switch the aube technologies TH115 Series Programmable Thermostat between Manual and Automatic mode?

Press the Mode/Ret button to switch between Manual and Automatic operation. Manual mode keeps a fixed temperature until you change it, which is useful for temporary comfort changes or troubleshooting. Automatic mode follows your programmed schedule and is better for energy savings and daily convenience. If the thermostat seems to ignore your schedule, check whether it was left in Manual mode, since that will override programmed periods until you switch it back.

What is the best way to calibrate or optimize the temperature settings on the aube technologies TH115 Series Programmable Thermostat?

For better comfort and efficiency, start by setting realistic Comfort and Economy temperatures rather than using very large temperature swings. If the room feels too warm or too cool, adjust the setpoint gradually and allow time for the floor or room to stabilize. The TH115 Series uses short heating cycles, so small adjustments usually work better than large ones. In floor-heating setups, also check the minimum and maximum floor limits to avoid uncomfortable surface temperatures.

Is the aube technologies TH115 Series Programmable Thermostat compatible with floor heating systems and external sensors?

Yes, the TH115 Series is designed for electric heating and works with floor heating when used with the proper sensor and configuration. In F mode, the thermostat reads the external floor sensor to control floor temperature directly. In AF mode, it uses the sensor to protect the floor while still controlling room comfort. Before installation, verify that your heating load, voltage, and wiring match the specific TH115 model you own, since compatibility depends on the exact version.

How should I maintain the aube technologies TH115 Series Programmable Thermostat for reliable long-term use?

Maintenance is simple but important. Keep the thermostat faceplate clean and dry, and dust the vents gently so airflow and display visibility are not affected. Check the wiring connections periodically if you notice inconsistent performance, especially after renovations or floor work. If the unit is not used for long periods, switch it to Standby only if recommended for your model and heating system. Also review your schedule seasonally so the programmed temperatures still match your comfort and energy goals.
