Setting the Time and Day
Refer to your thermostat's specific buttons (e.g., 'Set', 'Time', 'Day') to adjust the current time and day of the week. This is crucial for accurate program scheduling.
Programming a Schedule (7-Day Programmable)
The Model 8050 allows for individual day programming with four distinct periods: Wake, Daytime, Evening, and Sleep. This enables you to set different temperatures for different times of the day and for each day of the week.
A typical programming schedule might look like this:
| P1 Wake | P2 Daytime | P3 Evening | P4 Sleep | |
|---|---|---|---|---|
| Monday-Friday | 6 am (70°F) | 8 am (62°F) | 6 pm (70°F) | 10 pm (62°F) |
| Saturday | 6 am (70°F) | 8 am (62°F) | 6 pm (70°F) | 10 pm (62°F) |
| Sunday | 6 am (70°F) | 8 am (62°F) | 6 pm (70°F) | 10 pm (62°F) |
Consult the full programming instructions in the included guide for detailed steps on setting your personalized schedule.
Temporary Temperature Adjustment
You can temporarily adjust the temperature without altering your programmed schedule. The thermostat will maintain the new temperature until the next programmed period begins.
System Modes
Your thermostat offers various system modes:
- HEAT: The system will only activate the heating function.
- COOL: The system will only activate the cooling function.
- OFF: Both heating and cooling functions are disabled.
- AUTO: The thermostat automatically switches between heating and cooling to maintain the set temperature range.
- FAN ON/AUTO: 'ON' keeps the fan running continuously; 'AUTO' runs the fan only when heating or cooling is active.
Program Lockout
The program lockout feature helps prevent accidental changes to your settings, ensuring your schedule remains consistent.
Filter Usage Tracking
The thermostat keeps track of your filter usage and provides alerts when it's time to replace your furnace filter, promoting efficient system operation and air quality.
Maintenance
Battery Replacement
Replace the 2 AA batteries annually or when the low battery indicator appears on the display. Ensure the power to the HVAC system is off before replacing batteries. The thermostat continues to power most systems even if the batteries are dead or missing, but the display and programming features will be affected.
Cleaning
Clean the thermostat's exterior with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish or internal components.
Troubleshooting
If you encounter issues with your Ritetemp Model 8050 thermostat, consider the following common solutions:
- No Display/Blank Screen: Check battery installation and replace with fresh AA batteries. Ensure power to the HVAC system is on.
- System Not Responding (Heating/Cooling): Verify the system mode (HEAT, COOL, AUTO) is correctly selected. Check the circuit breaker for your HVAC system. Ensure wiring connections are secure.
- Incorrect Temperature Readings: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its sensor.
- Programming Issues: Review the programming instructions carefully. Ensure the current time and day are set correctly.
- Thermostat Does Not Work with Heat Pumps: Note that this thermostat does not work with Heat Pumps with auxiliary heat or 110V/240V baseboard heaters.
