  2. Remove the two AA batteries and wait until the display screen goes blank.
  3. Reinsert the batteries and place the face plate back on the wall. You should hear the face plate snap in place on the sub-base connected to the wall.

If the buttons or display are still not operating properly after resetting the thermostat and replacing the batteries, please return it to the place of purchase for a replacement.

Sensi Thermostat Not Turning On AC

The Sensi thermostat is not cooling. They have tried doing different things, but the thermostat just doesn’t seem to work at all.

How You Can Fix the Sensi Thermostat Not Cooling Is Here Below?

Checking Power

If your thermostat isn’t working as it should, one of the first things you should do is make sure it’s turned on. It’s possible that the reason your thermostat isn’t working is due to a power outage.

Similarly, most cooling equipment includes a power switch, if you didn’t know. The power switch may be located near the air handler or furnace. To put it another way, you must ensure that this switch (HVAC switch) is switched on.

Checking the Position of Air Handler and Furnace Door

Another thing that you will need to check is that you check the position of the air handler or the furnace door. It could be that you have some type of loose connection or poorly installed system due to which you are now experiencing issues while trying to cool down your house.

You’ll have to manually examine the placement of such components in any scenario. The panel and door should ideally be exactly straight in their placement so that they engage the safety switch that should be installed within the cabinet.

Reset Your Breaker

Resetting the breaker may assist in restarting the entire system, which may help to address the problem. You’ll need to examine your electrical panel to reset your breaker.

To fix this, all you have to do is to turn off your HVAC breaker. You will have to turn it back on shortly after which should then reset the breaker. After you have done so, you can proceed towards checking the system.

Sensi Thermostat Schedule Not Working

If it seems that the thermostat is turning your HVAC equipment on and off and the wrong time, first make sure your AM, PM, and temperature settings are all correct.

If you’re using Sensi with Ecovent, they override the Sensi app programming to reflect the settings in their respective apps.

There is also an Early Start feature that could be turned on. This feature is designed to start the program early to achieve your desired setting by the time you specify in the program. If that isn’t what you want, you can turn it off in the app.

Here are some examples of how Early Start works on different system types:

Single Stage (Conventional) Gas, Oil or Electric Heating / Standard Air Conditioning

For heating, assume during winter you set your thermostat back at night to 65°F and it’s scheduled for 70°F at 7 AM.

  • Early Start will turn on the heating system approximately 5 minutes early for each degree difference between the room temperature (65°F) and the scheduled comfort temperature (70°F). This works out to approximately 25 minutes.
  • At 6:35 AM the thermostat set point will change to 70°F and the heating system will start warming up the house.

Heat Pump or Heat Pump with Electric or Gas Auxiliary / Emergency Heating

For heating, assume during winter you set your thermostat back at night to 65°F and it’s scheduled for 70°F at 7 AM.

  • Early Start will turn on the heat pump system approximately 15 minutes early for each degree difference between the room temperature (65°F) and the scheduled comfort temperature (70°F). This works out to approximately 1 hour and 15 minutes.
  • At 5:45 AM the thermostat set point will change to 70°F and the heating system will start warming up the house. It will not bring on any Auxiliary heat until approximately 30 minutes before your scheduled comfort temperature, and then only if it requires three or more degrees to reach your selected setting.

How to unlock Sensi thermostat without app?

To avoid this problem, please reset your thermostat.

One of two methods can be used to accomplish this: Press and hold the Temp Up, Temp Down, and Fan buttons at the same time for 5 seconds (or until the thermostat goes blank) Remove the batteries and remove the Sensi from the wall until the screen turns blank.

To reconnect using an Android device, follow these steps:

  • Open the Sensi app.
  • Tap the + sign.
  • Choose the option, “Yes, it is on the wall.”
  • Press “Menu” and then “Connect” on the thermostat.
  • The app will prompt you to select your the Sensi network (Sensi-XXXXXX).

Why isn’t my thermostat connected to Wi-Fi?    

The warning “not connected to Wi-Fi” indicates that your Sensi thermostat has failed to connect to your home’s wireless network. The thermostat is unable to communicate with the Sensi cloud servers if it displays the message “connected to Wi-Fi, not connected to the Sensi cloud.”

This can result from a change to your Wi-Fi network password or network name, a home network problem, poor Wi-Fi signal strength, a router problem/compatibility issue, or a Sensi server problem

I am getting a “Server Error” when I open the app      

1. Press OK and check to see if you can get to the website sensicomfort on your smart device.

  • If you can access the site, check for “Normal” service status on the top of the “Support” page.
  • If your service status reads “Temporary Issues,” please wait an hour and then check the “Support” page for a “Normal” status.
  • Your Sensi thermostat will continue to heat and cool your home during this time.

2. If you cannot access the site, check your smart phone or tablet Wi-Fi settings. Your cellular data service may be interrupted, off, or out of range.

  • If the Wi-Fi connection is still unsuccessful, we recommend contacting your cellular or Internet service provider to reestablish service.

My heat pump cools in heat mode or heats in cool mode      

If your heating and cooling are reversed, then your wiring in the O/B terminal is probably reversed; proceed through the following steps until the issue is resolved.

  • Press “Menu” on the thermostat.
  • Press “Set Up HVAC Equipment.”
  • Press “Change settings.”
  • Switch the setting from “O” to “B” or “B” to “O”.
  • Press “Save.”
  • Press the back arrow button until you’re back to the main screen.
  • Test your systems to make sure they’re heating and cooling as expected.

My system cycles too fast (or slow). What should I do?       

The “Cycle Rate” setting, accessible in the Sensi mobile app, allows you to customize temperature control to suit your personal preference. Cycle rate options include Fast, Medium, and Slow.

  • For most homes with ducted heating and cooling systems, the Medium setting is optimal.
  • For most homes with hot water boilers or steam heating systems, the Slow heating cycle rate is optimal.
  • For the tightest temperature control, select the Fast cycle rate.
  • A faster cycle rate provides tighter temperature control and shorter on/off cycles. A slower cycle rate provides a bit wider of a temperature swing and longer on/off cycles. If you feel that your system is turning on and off too quickly, or causing wide temperature swings by turning on and off too slowly, simply adjust the cycle rate.

Unable to create a secure connection with Sensi thermostat

Make sure that you are using the correct Sensi PIN to connect to the Sensi network.

Use the dynamic code that appears on the touchscreen when the thermostat is in setup mode if you have a Sensi Touch. This is the PIN that you should be scanning or entering manually.

If you have a Sensi Smart Thermostat, make sure that the PIN you’re entering from the Welcome Guide matches the Sensi Security Code printed on the back of the thermostat faceplate. If they are not the same, use the Sensi Security Code.

Make sure your phone is connected to the Sensi network in your Wi-Fi Settings.

Depending on your Sensi model, you may connect to the Sensi network in the Sensi app. However, you can toggle to your Wi-Fi settings to make sure that your phone stays connected to the Sensi network. If it isn’t connected, you may need to check your Advanced Wi-Fi Settings (see below section for Android phones) or change the batteries on the thermostat. Your phone has to stay connected to the Sensi network to complete the setup.

Make sure you are selecting the right display options.

If you press Menu and then Connect, and the thermostat displays “11” make sure you’re selecting that option when you’re in the Sensi app.

Turn off Mobile Data or Switch to Mobile Data

On Android phones, Wi-Fi networks with poor internet connections are typically disconnected. The Sensi network does not have an internet connection, but you have to connect to it for setup purposes. For this reason, you may need to turn off Mobile Data and/or an advanced Wi-Fi option that switches to other networks automatically.

  • On your Android, tap Wi-Fi.
  • Tap Advanced Wi-Fi.
  • Look for settings called “Smart Network Switch,” “Switch to Mobile Data” or “Avoid poor connections.” If you see any of those settings, make sure they’re turned off while you connect Sensi to Wi-Fi.
  • Go back to your main Settings.
  • Tap Connections.
  • Tap Mobile or Mobile Networks.
  • Toggle Mobile Data off. This turns off cellular data use while you connect Sensi to Wi-Fi. You can turn this back on once you finish setup.
  • After you’ve turned both settings off, make sure to close out the Sensi app and reopen it before attempting setup again.

Reboot your phone

Power cycle your phone by finding the power button and rebooting.
