Overview of Product Range

Totaline is owned by the global company Carrier which is a large parts and supplies company for heating, ventilation, air-conditioning, and refrigeration systems.

Totaline produced a good number of thermostat models during their run. They’d have a specific model with different features according to your needs.

Check if your product is included in the list below. Let’s start with the Battery Powered Totaline thermostats. These are part of the Star brand. These models have a similar, modern-looking, neat design with Mode and Fan switches.

The Star brand is a line of programmable and non-programmable thermostats, identified by their P474 number. Models are tagged programmable if they have the “-1xxx” or “-2xxx” suffix. The designs from this series depend on the time of release. Most include separate Mode and Fan switches.

The FlatStat models use the numbers P374 and use screens with Thermoglow technology. These models have a visible sensor on the lower-left area. Sharing also the P374 line are Heat Cool & Heat Pump models using a different design, separated by commercial or residential products.

More features can be found further in the P3xx models:

  • P310 Basic series
  • P320 Easy series
  • P330 Smart series (not to be confused with smart thermostats)
  • P340-1xxx Deluxe, includes touchscreen functionality

The Gold product line by Totaline is a series of programmable thermostats, all sharing a similar design with a thermostat cover you can flip to open. Some of the models have a wide display screen with extra buttons, others have square displays and fewer buttons.

You also have the P7 product line:

  • P710 Performance Series
  • P720 Signature Series
  • P730 Premier Series

How to reset a Totaline thermostat?

Resetting is a common thing to consider when troubleshooting some issues. 

By resetting your thermostat, you won’t be simply powering it OFF and ON. You are resetting it to its factory default settings. Consider this carefully before doing the steps below. You might want to note down some of the settings or schedules before continuing.

  1. For four-button thermostats, press and hold the Mode button. While doing so, do the same for the Down button.
  2. Do this for up to 5 seconds, until some changes with the display. It might flash or display all icons.
  3. Press and hold either the Fan or Override button until the display changes again.
  4. To finish the process, press the Mode button two times.
  5. If your thermostat has more than four buttons including a Fan button, press and hold the Mode and Fan buttons for seven seconds.
  6. Release both buttons, then press and hold the Fan button until the display changes.
  7. Press the Mode button twice to finish.
  8. For thermostats with the Program switch, slide it to Set.
  9. Press and hold the Next button, until the display changes.
  10. Then, press the Next button. Afterward, press and hold it again until “Fd” is displayed.
  11. Press Next three times.

How to unlock a Totaline thermostat?

You might want to lock your Totaline thermostat to prevent any unauthorized access or accidental changes. Locking the thermostat keeps any keypad presses from activating it. Totaline thermostats include the functionality to set a keypad lockout.

You’d want to try this functionality if you have kids around the home who can’t resist pressing the thermostat buttons. Or you just want peace of mind with keeping your thermostat secure.

If you’ve forgotten the steps to unlocking your thermostat, don’t worry. Unlocking it takes only a few, easy moments of your time. Follow the steps below:

  1. Start by pressing and holding the Mode button.
  2. With the Mode button still pressed, press both the Up and Down buttons together.
  3. The locked icon will disappear and you’ll be able to operate the thermostat normally. The thermostat might not notify or display any changes after being unlocked. Try operating it to check if it is unlocked. To lock the thermostat again, just repeat the same steps. Press and hold the Mode button. Then, with the Mode button still held, press both of the direction buttons together. You’ll probably find it hard to forget the steps, seeing how easy it is.

How to set a Totaline thermostat?

Here we review common functions like setting the clock, changing operation mode or scheduling a program of temperatures.

Clock
  1. If the thermostat has a Program switch, skip to Step 5.
  2. If none, press and hold Mode, then press and hold Override for 2 seconds.
  3. Use the direction buttons to set values. Press Mode to proceed.
  4. Repeat Step 2 to finish.
  5. For models with a Program switch, slide to SET.
  6. Use the direction buttons to set values, then Next for the next setting. Slide the Program switch from Set to finish.
Operation mode
  1. Check for a Mode switch for Heat, Cool, or Off. Skip to Step 10 if none.
  2. Select your desired mode.
  3. Adjust the temperature using the direction buttons. If Program is in Run, you’ll override the schedule.
  4. For models without Mode and Program switches, press the Mode button.
  5. Adjust the Heat setting using the direction buttons, or proceed to the next step.
  6. Press Mode again to toggle the next options: Cool, Auto, Program On, or Off.
Programming
  1. Check for a Program switch. If none, skip to Step 17.
  2. Slide the Program switch to Set.
  3. Toggle the options using the Next button, while using the directional buttons to change the values.
  4. Slide the Program switch to Run to finish.
  5. For models without a Program switch, press and hold Mode.
  6. While still holding, press and hold the Up button for 2 seconds.
  7. Use the direction buttons to change values, and Mode to toggle the next settings.
  8. After setting your preferences, repeat Steps 17-18 to finish.

How to remove a Totaline thermostat?

When removing your Totaline thermostat, it’s recommended to power down your HVAC system for safety.

The steps for removing or detaching your Totaline thermostat depends on its type, according to how it’s powered. Check if your thermostat uses batteries as the main power source, or if it’s wired to your system and using batteries as a backup. These two types usually have different panel or attachment designs.

  1. If you have a battery-powered thermostat, a flat head screwdriver will be of help. You’ll be using it to insert the head into the slots to detach the thermostat.
  2. Locate the slots, which will likely be at the top area.
  3. Insert the screwdriver head to the slot, then twist the screwdriver to unsnap the attachment.
  4. Repeat Step 3 on the other slot.
  5. Pull the front panel starting from the sides with slots, then all the way.
  6. If you have a wired thermostat, the steps above might not work. First, get a good grip on your thermostat from the sides.
  7. Pull the panel off towards you, checking which side it budges. Try wiggling a little as you pull.
  8. If it doesn’t dislodge well, try detaching it vertically starting from the bottom then upward.

The Verdict

If you’ve lost the user manual for your Totaline thermostat, you don’t have to spend cash and call an expert yet. You’ll still be able to locate an online copy. Hopefully with the information we have here, you were able to troubleshoot your device.

    Hello,
    I love my Totaline RF thermostat so this morning when the room temp showed to be 54* (actual 73*) and furnace ran non stop. I replaced batteries. no change. I took unit outside and it did responded to o/s temp 42. but back inside doesn’t go above 54. as a last ditch effort do you think
    reset settings would help? sounds like, should not be done w/o serious consideration. I’m shocked at the cost for a replacement on-line $$$$$.
    appreciate your help! thank you

      Hi Gianeen,

      It is possible that there is a dust build up inside the thermostat which is stopping it from correctly measuring the temperature. You can use a soft brush to remove any dust or debris that could have built up. Ideally this is done with the cover removed however if your are not comfortable with that, then I recommend seeking the assistance of a professional.

      If that doesn’t work then I am afraid it may be time for a replacement as not correctly measuring the temperature is a major fault in the device. Newer smart thermostats can actually save you money in the long run so its worth considering either way.

      Hope this helps

        I kept checking my email for a response so, glad I found it here.
        thank you. I used canned air on it but did not help.
        So you don’t think doing the RESET would be of any value?
        My concern is could doing a reset make it worse? at least I can limp along as it is until i can find a replacement. really appreciate your input on this Thank you g

          A reset may work, however if it doesn’t you could end up with no heating controls at all. Probably best to leave it until you can get a HVAC professional in to repair or replace it.

          We work with Networx who could price up the job for you if you like – they give up to 4 quotes for the job. More details here

          Sorry can’t be of more assistance
