The Sensi Touch ST75 also features geofencing that uses your smartphone location and adjusts the temperature when you are at home or away. This feature automatically sets the thermostat to energy-saving “away” mode when your smartphone location exceeds three miles perimeter. Likewise, it resets your desired temperature when your smartphone position returns to that radius. According to Emerson, Sensi Touch can save up to 23% on your HVAC energy usage. In addition, the Sensi app provides smart alerts if it detects extreme temperature and humidity levels in your home. You will also receive a usage report that includes daily and monthly heating, cooling, and fan runtimes.

Final Words

Emerson thermostats can offer great benefits depending on the models. Different people have different needs and budgets. Some people prefer that the thermostat should be connected to the internet and allow them to control it through smartphones or tablets. For them, Emerson Sensi™ Wi-Fi Smart and Sensi™ Touch Thermostat are good options. For the people who are opting for a basic programmable or non-programmable thermostat and do not want anything fancy, Emerson Conventional Thermostat and Easy-Reader 7-Day Programmable Thermostat are our recommended choices. However, we believe that our reviews on the best 4 Emerson thermostats will help you to choose the best one based on your needs.


01. How to install Emerson thermostat?

There is a step by step easy DIY installation instructions on the Sensi™ App to install Sensi ST55 and Sensi touch ST75. You will find two options in the apps, “No, it needs to be installed,” or “Yes, it is on the wall.” If your thermostat is not yet installed and you want to install it yourself, choose the first option. It will guide you in each step of your DIY installation process. If your thermostat is already installed and you just need to connect it to WiFi, choose the second option. You can download the Sensi app on your smartphone or tablet to get the installation guidelines. For the non-wifi thermostats, an installation guide is provided that includes step-by-step instructions for easily installing the device.

02. How to reset Emerson thermostat?

If you notice that your thermostat is not working properly or shows erratic activities, you may need to reset your thermostat. To reset, press both the up and down arrows and the time button simultaneously for about 10 seconds until the display is blank. This procedure removes all the previous setting changes and put it back to the default ones. Remember, the system switch must be in heat or cool.

For resetting the Sensi™ Emerson thermostats, there is a different way. Remove the faceplate from the wall by pulling on both sides of the thermostat. Then remove the two batteries. When the display screen becomes blank, put the batteries again and push the faceplate back onto the wall. After you listen to the faceplate snap in place, the thermostat will be reset after a minute.

If your thermostat still not working properly after resetting, just contact your nearby heating/cooling service professionals or place of purchase.

03. How do I unlock my Emerson thermostat?

To unlock the Emerson digital thermostat, you need to press the MENU key first on the thermostat. Then select the thermostat lock option using the navigation keys from the settings menu. Then press the Unlock option located in the lower right side of the display, and you will be asked to enter the three-digit secret password that you had set earlier. Finally, enter the password and press the Unlock option again, and your Emerson thermostat will be unlocked.

However, you need the Sensi™ app to unlock multiple thermostats individually on the Emerson Sensi™ smart thermostats. Open the Sensi™ app and choose the thermostat which you want to lock from the dashboard screen. Then navigate to the setting and disable the keypad lockout by using the “On/Off” Lock Thermostat Display switch.

04. Do I need to install a common wire (c-wire) for Sensi™ Smart Emerson thermostat?

Sensi™ Smart thermostats work with a considerable range of heating and cooling systems without the c-wire. But, c-wire is required for heat-only, cool-only, and heat pump systems and Apple HomeKit. In contrast, Sensi™ Touch Smart (wifi) thermostat always needs a c-wire to install.

05. What is the difference between Emerson Digital programmable and non-programmable thermostat?

The Emerson programmable thermostat lets you set pre-programmed settings for comfort and energy saving. The temperature of your home’s hot and cooling system will change according to the pre-programmed settings for various times of the day. On the other hand, Emerson’s non-programmable thermostat will stay at the same temperature 24 hours a day that has been set. If any adjustments are needed in the temperature, it must be made manually every time.

06. How to replace the battery in Emerson thermostat?

You have to remove the faceplate from the sub-base to replace the battery. Just use your two hands to pull the faceplate straight towards you. Once the faceplate is detached from the sub-base, remove the old batteries from the faceplate and wait until the front display goes blank. Inset new batteries and place the faceplate back into the sub-base. You will hear a snap when the faceplate attached to the sub-base securely. Wait 1-5 minutes; the thermostat will automatically reconnect to WiFi.
