Best Heating Schedule for a House Empty During the Day: 5 Thermostats That Cut Waste
The best heating schedule for a house empty during the day is a simple set-back pattern: warm and comfortable before departure, lower while the house sits empty, and back to comfort shortly before the household returns. The thermostat is what makes that pattern automatic, and the five models below cover the range from a basic weekday/weekend unit to a Wi-Fi smart thermostat with remote control. Budget-conscious households, renters replacing an old dial unit, and owners of multi-stage HVAC systems each get a clear pick in the overview below.
The Picks at a Glance
| Product | Key Spec | Best Use | Price Tier |
|---|---|---|---|
| RTH20B Programmable Thermostat | 5-2 day schedule, 1 heat/1 cool | Simple weekday set-back on a budget | Budget |
| Honeywell Home RTH7600D | 7-day touchscreen | Different schedule every day of the week | Mid-range |
| Honeywell Home RTH7560E | 7-day flexible, extra-large backlit display | Easy reading and easy programming | Mid-range |
| LTX9100U Universal Programmable Thermostat | 7-day, 2-heat/2-cool | Heat pump and multi-stage systems | Budget |
| Honeywell Home RTH9585WF1004 | Wi-Fi smart color, 7-day, Alexa Ready | Remote scheduling and monitoring | Premium |
1. RTH20B Single-Stage Programmable Thermostat — Best Budget Pick
Schedule Type: 5-2 day (weekday/weekend)
System Compatibility: 1 heat / 1 cool, single-stage
Display: Digital, white housing
Programmability: Programmable set-back periods
Price Tier: Budget
This is the entry point into automatic scheduling. The 5-2 format splits the week into one Monday-to-Friday pattern and one Saturday-Sunday pattern, which fits the classic empty-house scenario almost perfectly: one set-back block for the workweek, a different one for the weekend. Installation is aimed at single-stage equipment only, so a conventional furnace and air conditioner pair is the target. The white housing is plain and unobtrusive, and the interface is built around buttons rather than a touch panel.
Households that leave at the same time every weekday and want the heat down without paying for a smart device are the natural buyers here. The pick earns its place on price and simplicity — there is nothing to configure beyond the two weekly patterns. The caution is flexibility: a household with rotating shift schedules or a midweek day off will find a 5-2 unit fighting them, and there is no app to override it remotely.
Trade-off: The 5-2 schedule cannot express a different pattern for each day, so irregular routines will need manual overrides.

2. Honeywell Home RTH7600D 7-Day Programmable Touchscreen Thermostat — Best for Varied Weekly Routines
Schedule Type: 7-day programmable
Display: Touchscreen
Programmability: Independent daily schedules
Mounting: Wall-mounted, standard wiring
Price Tier: Mid-range
Honeywell Home RTH7600D 7-Day Programmable Touchscreen Thermostat
Moving to a 7-day schedule means every day of the week can hold its own set of heating and cooling periods. That matters for households where someone works from home two days a week, or where a partner leaves at a different hour. The touchscreen replaces physical buttons and gives a cleaner face on the wall, and the unit is designed for standard low-voltage thermostat wiring.
This is the pick for a household whose week is not uniform but that still wants a set-and-forget solution without a network connection. It sits in the middle of the price range, above the budget single-stage unit and below the smart model, and the touchscreen is the main thing that separates it from the cheaper option. The caution is the interface itself: touch panels demand a deliberate press, and cold or dry fingers sometimes need a second attempt.
Trade-off: The touchscreen adds cost and complexity over a button interface without adding remote access or app control.

3. Honeywell Home RTH7560E 7-Day Flexible Programmable Thermostat — Best for Readability
Schedule Type: 7-day flexible programmable
Display: Extra-large backlit
Housing Color: White
Programmability: Flexible daily periods
Price Tier: Mid-range
The headline feature here is the extra-large backlit display. A thermostat is read in passing, often from across a hallway and often in poor light, and a large illuminated screen removes the squint from checking or adjusting the set-back. The 7-day flexible programming gives the same day-by-day control as the model above, and the white housing keeps it visually quiet on the wall.
Buyers who find small LCD readouts hard to read — or who simply want the schedule legible without walking up to the unit — are the right audience for this one. It earns its slot on usability rather than on features, since the scheduling capability is comparable to the other 7-day model. The caution is that a backlit screen is one more thing drawing a small amount of power and one more component that can fail; it is a reasonable trade for readability, not a free upgrade.
Trade-off: The large backlit panel is the main selling point, and buyers who do not need it can save money with a plainer display.

4. LTX9100U Universal Programmable Thermostat — Best for Heat Pumps and Multi-Stage Systems
Schedule Type: 7-day programmable
System Compatibility: 2 heat / 2 cool
Type: Universal replacement
Price Tier: Budget
7-Day Universal Programmable Thermostat LTX9100U Programmable 7-Day Thermostat, 2-Heat/2-Cool
The 2-heat/2-cool rating is what makes this unit different from the single-stage budget pick. Systems with a heat pump, a second heating stage, or separate heating and cooling stages need a thermostat that can address them, and this one is built as a universal replacement for that job. It still carries full 7-day programming, so the empty-house set-back pattern works exactly as it would on a single-stage unit.
This is the pick for a household replacing an old thermostat on a system more complex than a basic furnace and AC pair, especially where the budget does not stretch to a smart model. The universal labeling means it is intended to cover a wide spread of wiring configurations rather than one brand’s ecosystem. The caution is installation: multi-stage and heat pump systems need the wiring checked carefully, and a universal unit asks more of the person installing it than a direct single-stage swap.
Trade-off: A universal multi-stage thermostat demands correct wiring identification at install, and a mistake there is a service call rather than a settings fix.

5. Honeywell Home RTH9585WF1004 Wi-Fi Smart Color Thermostat — Best Smart Pick
Schedule Type: 7-day programmable
Connectivity: Wi-Fi, Alexa Ready
Display: Color touchscreen
Rating: Energy Star
Housing Color: Gray
The premium pick adds a network connection to the 7-day schedule. Wi-Fi means the set-back can be adjusted from a phone when plans change mid-day, and Alexa readiness opens voice control for quick changes. The color touchscreen is the most visible upgrade, and the Energy Star rating speaks to the efficiency intent of the product. The gray housing is a deliberate departure from the usual white.
This suits households that want the empty-house schedule to be adjustable remotely — the ones who come home early, travel, or want to confirm the heat came back on before walking in. It earns the top slot on capability rather than value. The caution is cost and dependency: this is the most expensive unit here by a wide margin, and its best features depend on a home network and an account setup that the simpler models never require.
Trade-off: The smart features carry a premium price and depend on Wi-Fi, so a network outage or router change removes the remote control that justified the cost.

Before You Buy
- Compatibility: Count the heating and cooling stages on the existing system before choosing; a single-stage thermostat will not control a heat pump or a two-stage system.
- Schedule format: A 5-2 unit covers a fixed weekday pattern; a 7-day unit is needed for a different routine on each day.
- Display: An extra-large backlit screen matters in a hallway or a dim room; a touchscreen matters for a clean wall face but not for function.
- Connectivity: Wi-Fi and voice control add remote adjustment and add setup work, a network dependency, and price.
- Wiring: Replacing an existing thermostat means reusing low-voltage wires; photograph the old terminal connections before disconnecting anything.
- Heating type: Homes with a heat pump or multi-stage equipment should confirm the thermostat lists that configuration before buying.
- Recovery time: The schedule is only as good as the set-back timing, so allow enough lead time for the system to bring the house back to temperature before anyone arrives.
Frequently Asked Questions
-
What is the best heating schedule for a house empty during the day?
A common pattern is a comfortable temperature for the morning, a set-back of several degrees during the hours the house is empty, and a return to comfort shortly before the household gets home. The exact set-back depends on the home’s insulation and the outdoor temperature. -
Is a 5-2 or a 7-day thermostat better for an empty house?
A 5-2 unit is enough when every weekday follows the same pattern. A 7-day unit is the better fit when the week is irregular — for example, someone working from home on some days. -
Does a smart thermostat save more than a programmable one?
A smart thermostat saves mainly through convenience: remote adjustment, scheduling from a phone, and easy overrides. A basic programmable unit already captures most of the set-back savings if the schedule is set correctly. -
How far can the heat be set back while the house is empty?
The safe amount depends on the home and the outdoor climate. A modest set-back protects pipes and plants while still cutting run time, and a heating professional can advise on the limit for a specific house. -
Can a thermostat with 2-heat/2-cool compatibility replace a single-stage one?
A universal multi-stage thermostat is built to cover a wider range of systems, but the wiring must be identified correctly at install. The reverse — putting a single-stage unit on a multi-stage system — is the combination to avoid. -
Does a Wi-Fi thermostat still work if the internet goes down?
The schedule stored on the unit continues to run, but remote control and voice commands stop working until the connection returns.
Bottom Line
For most households leaving an empty house every weekday, the best heating schedule is a 5-2 set-back pattern, and the RTH20B delivers it at the lowest cost with nothing to configure beyond two weekly programs. Households with irregular weeks should step up to a 7-day model, and anyone replacing a heat pump or multi-stage system should start with the LTX9100U’s 2-heat/2-cool compatibility. The Wi-Fi smart model is the pick only when remote adjustment is worth the premium.
