Trane thermostats are a customer favorite for settlers like you and us that can’t get enough of self-set temperature and all the good consequences it brings. But in case there are issues with the heating and cooling, such that you can do no more with your current schedule, you may need to know how to reset your Trane thermostat.

If you didn’t know already, Trane offers you both programmable and non-programmable thermostats with easy-to-use interfaces that make resetting much more comfortable than it has to be. Without further ado, here are the steps you are looking for.

How to reset Trane thermostat for Pump System:

You could lose the power to your heating or cooling system. In that condition, you will probably wonder if your pre-set settings will remain once you turn it back on. Generally, if you have a furnace and air condition connected to your thermostat, and it loses power when power returns, it will go back to default settings. However, if your heating/cooling system is a heat pump system, and now the traditional one, chances are the settings will act up.

Here is a step by step guide for you to reset the stat on a Trane 624:

  1. On the home screen at the center, you will find the Menu button. Start by pressing it. Next, press the Next button and keep doing it until you see Service being displayed on the screen.
  2. Once you get that, press the Select button. Keep pushing till you get to the point where it says Installer Setting. Now, again press Select.
  3. There should be a display of Equipment Type on your screen. Press Select.
  4. When you find Outdoor Select Type, press Select again. This will help you choose between the units AC and HP. The default is usually AC, but if you have a heat pump, pick HP. Once you are done, press Done.
  5. Then you will need to press Next. This will take you to Outdoor Unit Stages. Press Stage 1 or Stage 2 according to the type of unit you have. Then press Done and then Next.
  6. This next screen will take you to the Indoor Unit Type point. By default, it is set to oil or gas. In case you have a gas furnace system, you can keep it as is. But since we are talking here of heat pump systems, chances are you will probably want to change it, because there are electric air handlers with heat pumps. So you will have to keep searching for when it says Electric in the settings in place of Gas/Oil. Press Done, then Next.
  7. If you guessed it right, we should now opt for Indoor Heat Stages. Once you press Select, you may see Stage 1. This is actually what you have been set up for so long. Make sure that you’re confirmed of what you have set and then press Next. There should be a display of Indoor Blower Type. Pick it as Non-variable. Then press Next.
  8. Now, the Energizing Reversing Valve will be displayed. It should say With Cool. Lastly, press Next.
  9. Now you should be back at square one, but with everything changed. Now, you will have to press Done until you reach the main screen.

How to reset Trane thermostat after a Power Outage:

Now, there could be other reasons for your HVAC to lose power than your main power supply. It is possible during winter. During wintertime, it isn’t uncommon to have power outages for very long. Getting your thermostat back up after the agonizing winter outage can seem like a massive task, but someone has to do it! And no, it does not have to be a professional. You yourself can do it! But don’t you think after a power outage, everyone in the neighbourhood is attempting to turn on all their devices at once? Do you know what may happen for this? Another outage!

So you will need to slow down to turn the thermostat on well and safe. Then, follow these steps:

  1. Press the System button on the home screen of your thermostat.
  2. Set it to Heat. If it works, great. If not, your thermostat may be set at a higher temperature than what is in the room. So change the temperature to bring things back to normal.
  3. If it is summertime and faced the outage, set the system to Cool. If your room does not cool naturally, in that case, you may have it at a lower temperature than what is in the place. Change that, and you’ll be ok.
  4. If these don’t work, check the circuit breaker and turn it on and/or reset it. That should reset the thermostat too. Then you can wait a couple of minutes before changing the temperature settings.


You may need to reset your thermostat in these two circumstances: if the heat pump doesn’t work correctly and if there is a power outage. Of course, there could be several other reasons, but we chose to discuss these two for now.
