Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of your Venstar T1010 Single Day Programmable Digital Thermostat. Please read this manual thoroughly before installation and use to ensure proper function and to avoid damage to the unit or property.
The Venstar T1010 is designed for single-day programming, offering convenience and energy efficiency for your home or office environment. Its large display and continuous backlight enhance readability.
Safety Information
WARNING: Always turn off power at the main fuse or circuit breaker panel before installing or servicing the thermostat. Failure to do so could result in electrical shock or equipment damage.
- Read all instructions carefully before installation.
- Installation should be performed by a qualified technician if you are unsure about any steps.
- Do not short out the terminals on the gas valve or at the system to test the thermostat. This will damage the thermostat and void the warranty.
Setup and Installation
1. Mounting the Thermostat
- Turn off power to the heating/cooling system at the main circuit breaker.
- Remove the old thermostat from the wall.
- Label the wires connected to your old thermostat with the provided labels or by noting their terminal designations.
- Mount the new Venstar T1010 base plate to the wall using the screws and anchors provided. Ensure it is level for aesthetic purposes.
- Connect the wires to the corresponding terminals on the new thermostat base. Refer to the wiring diagram for your specific system type.

2. Initial Power-Up and Configuration
- Once wiring is complete, attach the thermostat body to the base plate.
- Restore power to the heating/cooling system at the main circuit breaker.
- The thermostat display should illuminate. Follow the on-screen prompts for initial setup, which may include setting the current time and day.
- Select your system type (e.g., Heat/Cool, Heat Pump) if prompted.
Operating Instructions
1. Understanding the Display
The large digital display shows the current room temperature, set temperature, system mode, and fan status. The continuous backlight ensures visibility in all lighting conditions.
2. Setting the System Mode
Press the "MODE" button to cycle through available system modes: HEAT, COOL, OFF. Select the desired mode for your comfort needs.
3. Adjusting Temperature
Use the "UP" and "DOWN" arrow buttons to adjust the desired set temperature. The display will show the new set temperature temporarily, then revert to the current room temperature.
4. Fan Operation
Press the "FAN" button to select fan operation: AUTO or ON. In AUTO mode, the fan runs only when the heating or cooling system is active. In ON mode, the fan runs continuously.
5. Programming a Schedule (Single Day)
The T1010 allows for a single-day program. This means the schedule you set will repeat every day.
- Press the "PROGRAM" button. The display will show the first program period (e.g., "WAKE").
- Use the "UP" and "DOWN" buttons to set the desired temperature for this period.
- Press "TIME" or "NEXT" (button label may vary) to adjust the start time for this period.
- Repeat for all program periods (e.g., "LEAVE", "RETURN", "SLEEP").
- Press "RUN" or "DONE" to save and exit programming mode.
Note: The thermostat will automatically follow the programmed schedule. To temporarily override the schedule, simply adjust the temperature using the UP/DOWN arrows. The override will remain active until the next program period begins.
Maintenance
1. Cleaning the Thermostat
Wipe the thermostat's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the internal components.
2. Battery Replacement (if applicable)
If your thermostat uses batteries (check your specific model's power requirements), replace them annually or when the low battery indicator appears on the display. Use high-quality alkaline batteries.
- Carefully remove the thermostat body from its base.
- Locate the battery compartment.
- Replace old batteries with new ones, ensuring correct polarity.
- Reattach the thermostat body to the base.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Thermostat display is blank. | No power, dead batteries (if applicable), or tripped circuit breaker. | Check circuit breaker. Replace batteries. Ensure thermostat is properly seated on its base. |
| Heating/Cooling system not responding. | Incorrect system mode, wiring issue, or system malfunction. | Verify system mode (HEAT/COOL/OFF). Check wiring connections. Consult an HVAC technician if the issue persists. |
| Temperature readings seem inaccurate. | Thermostat located near a heat source/draft, or internal sensor issue. | Ensure thermostat is not exposed to direct sunlight, drafts, or heat sources. If problem persists, contact support. |
| Programmed schedule not working. | Thermostat in "HOLD" or "OVERRIDE" mode, or incorrect program settings. | Ensure thermostat is in "RUN" or "PROGRAM" mode. Re-check program settings and times. |
