Aube Thermostat How To Use: Complete Programming And Operation Guide
Mastering an Aube thermostat requires understanding its specific button layouts, heating cycles, and programming modes to balance home comfort with energy efficiency. This comprehensive guide covers daily manual adjustments, 7-day programming schedules, advanced system settings, and troubleshooting steps for popular Aube residential heating controls.
Pre-Operation and Equipment Checklist
Operating an Aube electronic thermostat, such as the popular TH135, TH140, or TH115 series, relies on understanding its electronic interface rather than traditional mechanical dials. Before attempting to program or adjust your unit, it helps to understand the foundational equipment requirements and system scope.
- Essential Gear and Tools: Standard small flathead screwdriver (if accessing battery compartments or wiring baseplates), fresh AA or AAA alkaline batteries (depending on the specific Aube model), and a soft microfiber cloth for cleaning the LCD screen and housing.
- Mandatory Prerequisite Knowledge: Identification of your heating system type (line voltage electric baseboard, low-voltage conventional forced air, or hydronic heating), understanding the difference between manual hold mode and automatic programmed mode, and locating the system's circuit breaker for safety during maintenance.
- Benchmarks and Scopes: Programming a full 7-day schedule takes approximately 10 to 15 minutes. Battery replacement should occur annually before the heating season begins to prevent memory loss during power interruptions.
Step-by-Step Aube Thermostat Operating Workflow
Step 1: Navigating the Interface and Basic Manual Temperature Adjustment
Every Aube thermostat uses a specific arrangement of physical buttons beneath a protective door or directly on the faceplate. Locate the Up and Down arrow buttons, which control the setpoint temperature. Press either the Up or Down arrow once to illuminate the display and show the current setpoint temperature. Press the arrows repeatedly until your desired target temperature appears on the screen. The thermostat will automatically save this manual adjustment and display the ambient room temperature after five seconds of inactivity.
Pro-Tip: If your thermostat is locked or unresponsive, look for a small recessed button labeled "RST" (Reset) or check if the keypad lock feature is enabled via a combination of pressing both arrow keys simultaneously.
Step 2: Setting the Real-Time Clock and Day of the Week
Accurate timekeeping is critical for automated heating schedules to function correctly. Open the thermostat door or access the menu interface and locate the button labeled "Time" or "Day". Press the "Day" button until the correct day of the week appears at the top of the LCD screen. Next, press the "Hour" and "Minute" buttons to advance the clock to the exact local time. Press the "Mode" or "Return" button to exit the clock-setting menu and lock in your adjustments.
Warning: If your Aube thermostat loses power or its batteries die completely, the internal clock will reset to default, halting all programmed schedule cycles until time and day values are re-entered.
Step 3: Programming Daily and Weekly Heating Schedules
To maximize energy savings, switch your Aube thermostat from manual mode to automatic schedule mode by pressing the "Mode" or "Prog" button until the schedule icon appears. Most Aube models allow you to program four distinct periods per day: Wake, Leave, Return, and Sleep. Select the day you wish to program, then choose the period (Wake). Use the arrow keys to set the desired target temperature, followed by the "Hour" and "Minute" buttons to set the exact time that period begins. Repeat this process for the Leave, Return, and Sleep periods across all days of the week, or copy schedules to adjacent days if your model supports batch programming.
Step 4: Overriding Schedules Temporarily or Permanently (Hold Mode)
When your daily routine changes, you can override the programmed schedule without deleting your custom settings. Press the "Hold" button on the unit. The word "Hold" will appear continuously on the LCD screen. Use the Up and Down arrows to set your desired temporary temperature. The thermostat will maintain this exact temperature indefinitely until you press the "Hold" or "Run" button to return to the pre-programmed schedule.

Aube Thermostat Technical Specifications and Operating Modes
| Parameter | Manual Mode | Automatic Schedule Mode (PROG) | Early Start Feature (Adaptive) |
|---|---|---|---|
| Temperature Control | Constant fixed setpoint until manually changed | Variable setpoints based on 4 daily time periods | Automatically calculates heating start times |
| User Intervention | High (requires manual changes for sleeping/leaving) | Low (fully automated after initial programming) | Zero (automatically optimizes comfort vs. efficiency) |
| Primary Application | Guest rooms, irregular schedules, workshops | Standard residential living spaces, bedrooms | Energy-conscious households wanting precise timing |
| Override Capability | None required | Temporary or permanent manual hold overrides | Can be enabled or disabled in advanced settings |
Common Aube Thermostat Failures and Field Fixes
- Symptom: The screen is blank, completely unresponsive, or fading during temperature calls.
- Root Cause: Depleted internal batteries, loose battery contacts, or a tripped thermal cut-off switch in line-voltage models.
- Actionable Fix: Open the front cover, remove the battery carriage, and replace the old batteries with fresh high-capacity alkaline cells. Ensure proper polarity orientation. If the unit is a line-voltage model without batteries, verify that the dedicated circuit breaker in your electrical panel has not tripped.
- Symptom: The heating system does not turn on even when the setpoint is significantly higher than room temperature.
- Root Cause: The thermostat is stuck in Manual Hold mode at a low temperature, the heating cycle configuration is mismatched to your equipment, or the anticipator setting is incorrect.
- Actionable Fix: Press the "Run" button to cancel any active manual holds. Verify that the heating indicator icon (such as a flame graphic) is actively displayed on the LCD screen, confirming that the relay has engaged to send voltage to your heating elements or furnace.
- Symptom: The temperature in the room swings wildly before the heater turns on or off.
- Root Cause: Improper proportional-integral (PI) cycle length setting in the advanced configuration menu.
- Actionable Fix: Access the advanced configuration menu by holding the designated setup buttons (refer to your specific model's manual for pinholes or key combos) and adjust the temperature cycle rate to match your heating type—shorter cycles for forced air, longer cycles for electric baseboards or hydronic radiant systems.
Frequently Asked Questions
How do I unlock my Aube thermostat keypad?
Most Aube thermostats feature a keypad lock to prevent unauthorized changes by children or guests. To unlock the unit, press and hold both the Up and Down arrow buttons simultaneously for approximately five to seven seconds until the lock icon disappears from the LCD screen.
What do the 4 schedule periods (Wake, Leave, Return, Sleep) mean?
These four distinct time blocks allow you to tailor your home climate to your daily habits. Wake sets the comfort temperature for morning routines; Leave lowers heating when the house is empty for work or school; Return restores comfort before you arrive home; and Sleep reduces the temperature overnight for optimal sleeping conditions.
Can I use rechargeable batteries in my Aube thermostat?
It is strongly recommended to use standard, high-quality alkaline batteries rather than rechargeable batteries. Rechargeable cells often output a lower nominal voltage (1.2V instead of 1.5V), which can cause premature low-battery warnings, erratic LCD screen behavior, or sudden loss of programmed memory.
How do I change the temperature display from Celsius to Fahrenheit?
To switch between temperature units, access the advanced configuration menu or remove the thermostat faceplate to locate the internal configuration jumper switch. Flip the switch or toggle the software setting labeled °C/°F, then reinstall the faceplate and press the reset button if required.
What is the Early Start feature on my Aube thermostat?
Early Start is an advanced algorithmic function that calculates the exact time your heating system needs to turn on so that the room reaches your target temperature precisely at the scheduled time (such as when you wake up). This eliminates the need to manually program your heating schedule to start an hour early.
