How do you program a thermostat? On almost any programmable thermostat, the steps are the same: set the current time and day, press the button labeled "Program" or "Set," then enter a target temperature for each period of the day — usually Wake, Leave, Return, and Sleep — for weekdays and weekends. Save, and let it run. The buttons and menus differ by brand (Honeywell, Emerson/Sensi, Lux, White-Rodgers), but the four-period logic is nearly universal. Below is the step-by-step for any brand, the brand-specific quirks, and why so many people give up halfway through.
If you'd rather watch than read, this walkthrough of programming a Honeywell thermostat has been viewed more than 1.6 million times — because the process is the same head-scratcher for almost everyone. Most programmable thermostats share the same layout and settings, so it's useful even if yours isn't a Honeywell.

How to Program a Thermostat: The Universal Method (Any Brand)
Strip away the branding and every programmable thermostat asks for the same five things. Get these right and you've programmed it, whatever the logo says.
1. Set the current time and day
This is the step people skip, and it breaks everything downstream. A programmable thermostat runs your schedule off its internal clock. If the time or day is wrong, your "Wake" setting fires at the wrong hour. Look for a Clock, Time, or Set button and set the exact time and correct day of the week first.
2. Enter program mode
Press the button labeled Program, Set, Edit, or Schedule. On many models you hold it for a few seconds. The display will start blinking on the first time period — that's how you know you're in.
3. Set a temperature for each of the four periods
Nearly every programmable thermostat divides the day into four periods:
- Wake — when you get up and want the house comfortable
- Leave (sometimes "Day" or "Away") — when the house is empty
- Return (sometimes "Evening") — when you get home
- Sleep (sometimes "Night") — overnight
For each period, use the arrows or up/down buttons to set the start time, then the target temperature. Press Program/Next to advance to the following period.
4. Repeat for weekends
Most units let you set weekdays (often shown as 5-2, or Mon–Fri) separately from weekends (Sat–Sun). Some higher-end models offer 5-1-1 (weekdays, Saturday, Sunday separately) or full 7-day programming. Set the weekend periods the same way — usually a later Wake time and a warmer or cooler Leave setting since you're home more.
5. Save and switch to "Run"
Press Done, Save, or simply wait for the display to stop blinking. Then make sure the mode is set to Run (not Hold). If it says "Hold," it's ignoring your schedule and holding one fixed temperature — the single most common reason a freshly programmed thermostat "isn't working."
The one setting that undoes all your work: Hold. Pressing the temperature arrows on a running schedule usually triggers a temporary hold until the next period. Pressing "Hold" makes it permanent — and your schedule stops running entirely. If your programming never seems to take effect, check for Hold first.
Brand-Specific Steps
The universal method covers the logic. Here's where the buttons and menus differ on the most common brands.
Honeywell (RTH series and similar)
Honeywell makes the most common programmable thermostats in American homes. On the classic RTH models, press Set (or the physical Program slider), then Set Schedule. Use the arrows to change each period's time and temperature, pressing Next to move through Wake / Leave / Return / Sleep. Press Done to save. On touchscreen RTH models (like the RTH8000 series), it's Menu → Edit Schedule. To cancel a hold, press Run Schedule or Cancel.
Emerson / Sensi and White-Rodgers
Older Emerson and White-Rodgers units use a Menu or Program button, then step through the periods with up/down arrows. Newer Emerson Sensi models are Wi-Fi thermostats — you program them entirely in the Sensi app rather than on the wall, which is closer to how a smart thermostat works.
Lux
On most Lux programmable models, press Prog to enter programming, use the arrows to set time and temperature for each period, and press Time/Day or Run to exit and save. Lux units often have a dedicated 5-2 or 5-1-1 switch on the back or side.
Older Nest and other digital "learning" units
If you have an older Google Nest or a learning thermostat, you generally don't program four fixed periods by hand — you adjust the temperature over the first week and it builds a schedule from your behavior, then you fine-tune it in the app. Worth noting: most of these are full smart thermostats and typically require a C-wire to run. That's a different install path than a basic programmable unit — here's what a C-wire is and why it matters.
No manual? Find your exact model's guide
Every brand posts model-specific PDF manuals online. Search your exact model number (printed on the back of the unit or behind the faceplate) plus the word "manual." The five universal steps above will still map onto whatever menu you find.
What to Actually Set It To
Programming the thermostat is only half the job. The temperatures you choose are what determine whether it saves you anything.
The US Department of Energy's guidance is specific: you can save up to 10% a year on heating and cooling by setting your thermostat back 7–10°F from its normal setting for 8 hours a day — for example, while you're at work and while you sleep. A common starting point:
- Winter Wake: ~68°F Leave/Sleep: ~60–62°F
- Summer Wake/Return: ~78°F Leave: ~83–85°F
This matters more than it sounds, because heating and cooling is 52% of a typical US home's energy use — the single biggest line on your energy bill, according to the EIA. Getting the setbacks right is the highest-leverage thing a thermostat does.
Here's the catch the DOE's own data exposed: the savings only happen if the setbacks actually run. The EPA suspended its ENERGY STAR program for programmable thermostats in 2009 after field studies couldn't confirm any real-world savings — because so many people override the schedule, hold a fixed temperature, or never finish programming at all.
Or: The Version Where You Never Do This Again
Step back and look at what programming a thermostat really is: standing at a wall, pressing arrows through four periods, twice, hoping you didn't leave it on Hold — and then repeating the whole thing every time your routine changes or Daylight Saving Time shifts.
It would be a lot easier if you could just program it from your phone. That's what CliQ is: a programmable thermostat you control from your phone.
You set your Wake / Day / Evening / Night schedule once in the app, with real numbers you can see instead of a blinking wall display. Change of plans? Adjust it from the couch, the office, or the car. Leaving for the weekend? One tap puts it in Away mode instead of you re-programming around a trip. And because the schedule lives in the app, it doesn't reset when the batteries change or the clock drifts.
The reason people don't get the DOE's 10% isn't that setbacks don't work — it's that manual programming is annoying enough that the schedule quietly stops running. Move the schedule to your phone and the savings stop depending on your patience with a wall unit.
| Task | Old Programmable Thermostat | CliQ |
|---|---|---|
| Set a schedule | Arrows on the wall, 4 periods × 2 day types | In the app, numbers you can see |
| Change it after a plan changes | Walk to the wall, re-enter | From your phone, anywhere |
| Leaving for a trip | Re-program or override | One-tap Away mode |
| Install | Already on your wall | Minutes, no C-wire, often no tools |
| Price | $25–$60 | $69.99 |
CliQ installs without a C-wire by design — it runs on two AAA batteries, and the connectivity lives on a small hub that plugs into a wall outlet. If you have a compatible Honeywell RTH wall plate, CliQ clicks right onto it with no tools. If you're weighing the upgrade, this guide covers it in depth: the best smart thermostat for programmable thermostat owners.
Tired of programming a wall? CliQ is the programmable thermostat you control from your phone — set it once, change it from anywhere.

How do I program a thermostat step by step?
Set the current time and day first, press the Program or Set button, then enter a start time and target temperature for each of the four daily periods (Wake, Leave, Return, Sleep), repeat for weekends, and save. Finally, make sure the thermostat is in Run mode, not Hold — Hold ignores your schedule and holds one fixed temperature.
Why won't my thermostat follow its program?
The most common reason is that it's set to Hold, which overrides the schedule and keeps one fixed temperature. Press Run Schedule or Cancel Hold to fix it. Other causes: the clock or day is set wrong, or dead backup batteries wiped the schedule.
What temperature should I set my programmable thermostat to?
The US Department of Energy suggests setting back 7–10°F from your comfort temperature for 8 hours a day (while away and asleep) to save up to 10% a year. A common winter schedule is about 68°F when home and 60–62°F when away or asleep; in summer, about 78°F when home and 83–85°F when away.
Are all programmable thermostats programmed the same way?
Mostly, yes. The buttons and menu names differ across Honeywell, Emerson/Sensi, Lux, and White-Rodgers, but nearly all use the same four-period logic (Wake, Leave, Return, Sleep) for weekdays and weekends. Learn the logic once and you can program almost any brand.
Can I program a thermostat from my phone?
Not a basic programmable thermostat — those are programmed only at the wall. A smart thermostat like CliQ lets you set and change the schedule from an app on your phone, toggle Away mode with one tap, and adjust the temperature from anywhere. CliQ costs $69.99 and needs no C-wire.
Do programmable thermostats really save money?
They can — the DOE's 10% savings figure is real — but only if the setbacks actually run. The EPA suspended ENERGY STAR certification for programmable thermostats in 2009 because field studies found people frequently override or never properly set them. Automating the schedule (and controlling it from a phone) is what makes the savings reliable.
