Update Your Thermostat Schedule
Updating your thermostat schedule is one of the simplest ways to lower your energy bill without sacrificing comfort. Whether you run a central heating system, furnace, heat pump, or air conditioner, you need a way to adjust your indoor temperature as the seasons change, higher ranges heading into winter, lower ones through summer. Here’s how thermostat scheduling actually works, and what a properly set schedule can genuinely save you.

A Brief History and What “Thermostat” Actually Means
Where the Name Comes From
Before thermostats existed, there was no practical way to manipulate indoor temperature automatically. The word itself comes from two Greek roots: thermos, meaning heat, and statos, meaning standing or status, together describing a device that keeps heat at a consistent level.
The Four Types of Thermostats
Non-Programmable Thermostat
The most basic option, offering manual controls for temperature and fan settings with no ability to pre-program schedules.
Programmable Thermostat
The near-opposite of non-programmable models, allowing you to set specific temperature and fan schedules for individual days or an overall pattern across the week. These may include a touchscreen with added functions or simple manual buttons.
Wi-Fi Thermostat
Still a programmable thermostat at its core, but with Wi-Fi connectivity added, allowing you to access and adjust settings remotely from a computer, tablet, or smartphone.
Smart Thermostat
Also programmable, but with automation layered on top. Smart thermostats connect with other smart home devices and use built-in learning capabilities to adjust temperature, humidity, and fan settings automatically based on your habits, often with voice control support through assistants like Amazon Alexa or Google Assistant.
How Thermostat Scheduling Actually Works
The Schedule Button
Every programmable thermostat includes a schedule button. Pressing it brings up the days of the week, letting you choose which days to program individually or as a group.
The Four Daily Periods
Each day typically breaks into four time periods you can customize:
- Wake: the period when you get up in the morning
- Leave: the time you head out for the day
- Return: when you typically come back home
- Sleep: when you go to bed for the night
For each period, you set both a heat and cool target along with the specific time it applies, and the thermostat follows that pattern automatically until you change it.
Overriding and Holding Your Schedule
Temporary Overrides
Your schedule runs automatically, but you can override it for a specific period. If you come home and the set temperature feels too low for a winter evening, you can adjust it temporarily until your sleep period begins, after which it returns to the regular schedule.
Temporary vs. Permanent Holds
Pressing the hold button once typically locks your thermostat at a permanent hold using the current setting. Pressing it twice usually lets you set a temporary hold for a specific number of hours, useful for short-term changes or an extended hold while you’re away on vacation or a business trip.
Understanding Fan Settings
Your thermostat’s fan settings are tied directly to your HVAC system’s blower, with three common options:
- ON: Runs the fan continuously
- AUTO: The most energy-efficient setting, especially in winter, since the fan only runs when heating or cooling is actively on
- CIRCULATE: Runs the fan for roughly 30% of every hour to help even out indoor temperature without running continuously
The Real Benefits of a Thermostat Schedule
Genuine Energy Savings
According to Natural Resources Canada, a properly used smart or programmable thermostat can save close to 8% on annual heating and cooling costs, with the U.S. Department of Energy citing up to 10% savings specifically from a 7-10°F setback maintained for 8 hours a day. These are real, verified figures, not the inflated 20-30% numbers sometimes seen in older marketing material.
Consistent Comfort
Rather than manually cranking your system up or down throughout the day, a proper schedule maintains a steady, comfortable temperature automatically.
Less Wear on Your Equipment
A well-set schedule keeps your system running efficiently rather than working in constant, manual bursts, which can reduce wear and tear and lower long-term maintenance costs.
Less Time Spent Adjusting
Once your schedule is set correctly, you’re not stuck manually adjusting temperature, fan, and humidity settings throughout the day and night.

FAQs
How much can a thermostat schedule actually save me?
Roughly 8 to 10% on annual heating and cooling costs, according to Natural Resources Canada and the U.S. Department of Energy, not the 20-30% sometimes cited in older marketing materials.
What's the difference between a programmable and a smart thermostat?
A programmable thermostat follows a manually set schedule you create. A smart thermostat also follows a schedule but uses automation and learning to adjust settings on its own based on your habits.
What does the AUTO fan setting actually do?
AUTO runs your fan only when your heating or cooling system is actively running, which is generally the most energy-efficient setting, especially in winter.
What's the difference between a temporary and permanent hold?
A permanent hold locks your thermostat at the current setting indefinitely. A temporary hold lets you set a specific temperature for a defined number of hours before returning to your regular schedule.
Can Vacu-Man help me program my thermostat?
Yes. Our heating and cooling technicians can set up your schedule based on your household’s routine and walk you through basic troubleshooting if needed.
