Setting the correct time on a Robertshaw thermostat ensures accurate daily schedules, energy savings, and reliable program changes. This guide explains step-by-step how to set the clock, adjust for daylight saving time, and verify that your programmed temperatures follow the intended times. It covers common models used in American homes and offers troubleshooting tips if the clock won’t update. Whether you’re updating after a power outage or syncing with a new schedule, these methods help maintain precise control of heating and cooling.
Understand The Clock System And Basic Model Differences
Robertshaw thermostats come in various series, including digital programmable and non-programmable models. While many steps are shared, some models use different menus or buttons. Typical features include a Menu or Set button, arrow keys to adjust values, and a Save or Confirm function. For most units, you will access the clock settings within the main menu and set the current time, confirm changes, and optionally enable daylight saving time. Always consult the specific model’s manual if any step seems different.
Steps To Set The Time On A Digital Robertshaw Thermostat
These steps reflect common procedures found across popular Robertshaw digital thermostats. If your unit looks different, use the same principle: enter the clock or time setting, adjust hours and minutes, then save.
- Press The Menu Or Settings Button: This opens the main settings menu.
- Select Clock Or Time Option: Navigate using the up/down arrows until the clock setting is highlighted.
- Set The Time: Use the Hour and Minute selectors. Ensure the correct AM/PM if required by the unit.
- Choose 24-Hour Or 12-Hour Format: Some models offer format options; select the one you prefer.
- Save Or Confirm: Press Done or Save to apply changes.
- Exit The Menu: Return to the main screen and verify the time display.
Tip: If the unit reverts to an incorrect time after power is restored, you may need to re-enter the clock settings and re-save. Some models automatically reset after a power interruption and require a manual update.
Enabling Daylight Saving Time And Auto-Adjust Features
Many Robertshaw thermostats offer a daylight saving time (DST) setting or an Auto DST option. Enabling this feature helps the thermostat automatically adjust the clock during spring and fall changes.
- Enter Menu > Clock > DST or Auto DST.
- Enable DST Auto if available, and confirm your time zone.
- If there is a separate DST Start/End setting, verify the dates align with your region.
Note: If the thermostat lacks an Auto DST option, you will need to update the time manually when DST starts and ends. Always confirm the time zone is correct for your location to avoid mismatched schedules.
Verifying Schedules After Setting The Time
After setting the time, confirm that programmed programs align with the intended hours. Incorrect clock settings can shift when programs turn on or off, causing uncomfortable temperatures or wasted energy.
- Check Each Program: Review wake, morning, daytime, and nighttime setpoints to ensure they reflect the correct times.
- Test A Cycle: Set a temporary program to start in the next few minutes and observe the thermostat’s response.
- Review Heat/Cool Status: If the unit is not maintaining the desired temperature, re-verify the current time and program order.
Pro tip: If the thermostat offers a “Test” or “Hold” feature, use it to verify current settings without altering the entire schedule.
Common Issues And Quick Fixes
Several issues can prevent correct time display or scheduling. Here are practical fixes you can try at home.
- Clock Not Staying Correct After Power Loss: Re-enter time settings and save. If power outages are frequent, consider a unit with a backup battery or a more robust power supply.
- Time Display Flashes Or Is Inaccurate: Reset the clock by removing and reapplying power for a few seconds, then set the time again.
- DST Not Applying Automatically: Ensure Auto DST is enabled and the correct time zone is selected. If not available, manually adjust at DST transitions.
- Program Not Following Time: Revisit each program’s start times and confirm the current time is accurate. Re-load the schedules if needed.
Maintenance Tips For Reliable Time Keeping
Regular maintenance helps keep the clock and programs accurate and reliable. Simple checks can prevent timing issues from escalating.
- Periodically Confirm Time And Date: Especially after power events or renovations in the home.
- Update Software Or Firmware If Available: Some models support firmware updates that improve clock reliability and scheduling.
- Keep The Thermostat In A Climate-Controlled Area: Extreme temperatures or humidity can affect internal components and display clarity.
- Document Your Settings: Save your current schedules and time settings in a note for quick recovery after maintenance or resets.
