Wait for 2 minutes, and the device will be added.

If the device pairing failsYou can retry as follows:
1. Reset the device and reconfigure the network. See the first step for the reset operation.
2. Move the device close to the Wi-Fi router to connect the network
3. Confirm whether the Wi-Fi type is 2.4G. If it is 5G Wi-Fi, you need to switch the Wi-Fi to 2.4G
4. How to switch the Wi-Fi to 2.4G?
A. The thermostat will stop heating or cooling based on your differential temperature setting.
You can set the value of the minimum difference between the current temperature and set temperature before the system calls for heat or cool. A smaller difference means shorter cycle times, whereas a larger difference results in longer cycle times. By default the differential temp is 1°F which means if you the heat is set to 65°F, we will turn the HVAC on when the temperature falls to 64°F and turn off the heat when the room temperature reaches 67°F. A higher Differential Temp will help prevent unnecessary short cycles from wearing your heating/cooling system and reduce starting costs. The temperature range is adjustable from 0.5 to 3 °F (0.5 to 3 °C) by going to Settings > Saving goal & Schedule > Differential Temp.
A. Yes, the degrii thermostat is able to access the outdoor temperature of your location. The heat pump will not be used when the weather outside is below 35 degrees Fahrenheit and only aux heat will be used in this case.
Some thermostats have both “Conventional” and “Heat Pump” modes, causing them to have two lines of terminal labels. Your system is only using one of these two modes. All you have to do is figure out which mode is currently in use and then use that set of labels for the compatibility checker.

If you don’t know what system that you have off-hand, no worries! Here are a few dead giveaways:
1. Try turning on the heat, then check if your outside condenser/air conditioning unit starts running. If it does, you have a heat pump system.
2. If turning on the heat doesn’t make your outside unit run, you’ll probably hear sounds coming from your basement, closet, or the ceiling when your heat is on. This would mean you have a conventional system.
3. Check out the labels on your condenser or indoor air handler for a model number or name. You can likely search this up to figure out what type of system you have.
4. Check your HVAC control board for the wire labels. The control board will most likely have only one set of labels which corresponds to either a heat pump or conventional unit.
Yes. By using the 24v power adapter, the Degrii Thermostat will be able to work with a 2-wire system.
You will need to remove the front cover of your old thermostat, then remove jumper wire if any. Follow the wire from the wall to the terminals of the control board where the wire is connected. Finally, label the wires based on the letter on its terminal accordingly. In this example, you would select Rh, G, Y, and C.
Please locate your control board, it will be near your HVAC system, usually in the basement. The HVAC control board is where the thermostat wires connect to your heating and cooling system. In most cases, the control board can be found at your furnace or air handler. If you have furnace you will need to open your system's cover.

The control board should look similar to the picture above. The control board has wires with the same colours and thickness as the wires at the thermostat side. You will also find labelings similar to those at the thermostat.
Yes, the Degrii Thermostat will reconnect with your Wi-Fi once it powers back on, and it will resume its mode and schedule.
If your device is offline for a long time, you can only manually reset the device to pairing mode, and then manually add the device again. The function of remotely resetting the device is not supported.
When a Heat Pump system is set up, the heat and cool stage can be configured in reverse. If you have Heat Pump system and your heating/cooling is reversed, swap them into the correct configuration in Settings -> Advanced -> Swap Heat and Cool.
NOTE: "Swap Heat and Cool" is not available for a conventional system (no O/B wire)
Yes, you can share the thermostat in your home with family members and friends by:
1. On the Degrii app home page, go to Home mangement in the upper left corner.


2. Select the home in which the devices you want to share are located, click Add Member and select the method of invitation.


No, the Degrii thermostat doesn't work with millivolt systems.
Yes, if you have a G-wire, then you can control the fan even if you have CWA installed. Check out fan options here:
The Degrii Thermostat has 2 fan control modes as shown below:
- Auto - This mode has a default fan cycle of 0 min/hr. The fan will only run during the heating or cooling stage and turns off immediately the heat turns off (without Coast to Cool activated).
The fan cycle can be configurable in Settings -> Advanced -> Fan Cycle. Cycle is configurable from 0min/hr to 30min/hr.NOTE: This is the minimum amount of time the fan will run each hour. The time the fan runs cooling stage heating stage also counts towards fan cycle time.
- On - The fan will run continuously.
In Fahrenheit it is 0 decimal places e.g., (70°F), and 1 decimal place in Celsius e.g., (23.5°C)
Yes, during the setup you can set this. It is called "Energize" in the Degrii app setup for dehumidifier.
Yes, the Degrii thermostat is able to work with up to 12 Degrii remote thermostats (sensors).
Yes. You can use your mobile internet hotspot to set up the thermostat if you do not have a working Wi-Fi.
If you want to reset the thermostat,
1. Press and hold the Menu button on the thermostat for 5s.
2. Select "y" by clicking the right button.

3. Click the Menu button to reset the thermostat.

The Wi-Fi indicator light will blink continuously after resetting the thermostat.
The minimum allowable temperature difference between heating and cooling is 5 degrees Fahrenheit (2.5 degrees Celsius). To set the Auto mode temperature:
1. Tap either the left button or right button on the thermostat main page to display the "Heat to" or "Cool to" setpoint temperatures respectively.
2. Tap the right or left to increase or decrease the temperature.
Did you follow the Degrii app installation instructions and is everything well connected but still no power? Power comes from the Rc and C terminal of your thermostat. Ensure that these two wires are well connected both on the thermostat and on the HVAC control board.
Usually, the thermostat screen shows "Degrii" during the first time installation. Also, when the thermostat is Factory Reset, the screen shows the Degrii logo. This is perfectly normal. All you need to do is open the Degrii app and set up the thermostat all over again (Add thermostat).
The heat and cool stages change based on two factors: the temp difference (set Temp - current temp), and run time, which depends on your system type. For a gas furnace, after the default run time of 35 mins, if the current temperature is not close to the set temperature, the system will move to the next stage.
Stage 1: 1 - 4 degrees from the set temp
Stage 2: 4 - 8 degrees from the set temp
No. You can not manually set the heating or cooling stage to be used by the system.
You can submit a log through the Degrii app platform home page.
- Go to Me
- Click on Settings
- Click Degrii Support, Select Submit Log and write details of the issue.
- Submit the Log and write down the Ticket ID to our customer support agents.
It is a self connection, from one thermostat terminal to another thermostat terminal. It is quite common on older model thermostats. Usual jumper connections exist:
- Rc -- Rh
- Y1 -- Y2
- W1 -- W2
All of these jumper cables should be removed when installing Degrii Thermostat.
Yes, it will keep operating based on the last working schedule; you can control your temperature or change status from the thermostat device as well.
Check the right side of the thermostat to see if it still has Wi-Fi connection. If the thermostat Wi-Fi is disconnected, the Wi-Fi light will be off. If the thermostat is connected to the Wi-Fi, there may still be a delay in the connectivity between the app and thermostat.
Yes. You can use the Degrii thermostat without the app.
The Degrii thermostat is very accurate, but it may require being calibrated. Temperature can be adjusted with Temperature correction, found in Settings->Advanced->Temperature Correction.

No. The Degrii thermostat uses algorithms to ensure that your heat turns on when needed and turns off at the desired temperature.
No, the Degrii thermostat is unable to work with communicating equipment even if your wire labels are compatible. Using Degrii thermostat on communicating equipment may result in you losing some features and cause low efficiency of your system.
The K terminal located on Honeywell thermostat's combines the Y and G wires. It does this using the Honeywell wiresaver. The Degrii system is not compatible with the Honeywell wiresaver. However, your system is compatible with Degrii thermostat once the Honeywell wiresaver is removed. Please follow the following steps to install your Degrii thermostat.
1. Take photos of your control board, thermostat wiring and Honeywell wiresaver.
2. Remove the Honeywell wiresaver.
At the Control Board
3. On the "Thermostat" side of the Honeywell wiresaver, label the wires as follows.
a. Rc terminal -> Rc Label
b. K terminal -> Y Label
c. C terminal -> G Label
d. W-O/B terminal -> Please follow the W-O/B terminal wire from the wiresaver to the control board. Label the wire on the thermostat side of the wiresaver corresponding to the terminal label found on the control board.
NOTE: If the control board is also labeled W-O/B. You will need to determine if your system is heat pump system(O/B) or conventional(W).
4. With wires correctly labeled remove the wires from the wiresaver.
5. Now remove the wires from the control board connected to the wiresaver.
6. Wire the labelled wires to their corresponding terminals on the control board.
NOTE: You may notice you no longer have a C-wire, don't worry they will walk you through setting up the Degrii CWA.
7. Correct the thermostat wires
At the Thermostat
1. Remove the thermostat cover panel (Your wiring should be similar to the wiring on the above left side photo).
2. To be compatible with the Degrii thermostat, wires K and C will need to be adjusted.
3. Place the wire in the C terminal into the G terminal.
4. Place the wire in the K terminal into the Y terminal.
Your system is now compatible with the Degrii thermostat. Please open the Degrii app and add a new thermostat. Select the wires currently connected in your system and the App will guide you through how to connect the Degrii C-Wire Adapter.
Some systems have GH and GC terminals on the control board with a jumper wire between R and GH. The GH provides low fan speed during heating, while the GC is for high fan speed during cooling.
1. Disconnect the wire connected to GH and connect it to R
2. Disconnect the jumper wire between R and GH
3. Connect a jumper wire between GH and W
4. Install the CWA if there is no C wire at the thermostat
5. During the type of heating system selection, choose radiator or in-floor radiant
The emergency Heat can only be turned on manually by going to Settings -> Advanced. This option is only available if the User selects Emergency heat during the setup process. It has a max runtime of 30 mins.
If your heat doesn't turn off after reaching the set temperature, in other words, the room gets too hot - hotter than the set point temperature. Here are some things that could cause that problem:
1. The thermostat might have been configured wrongly. For instance, if the system is a conventional unit but you configure it as a heat pump. This could cause this to happen.
Verify the kind of system you are using (Heat pump or Conventional unit) and make sure that you wire the system correctly.
2. In some cases, the temperature will go up about 2 to 4 degrees higher than the set point temperature because the residual heat from the furnace causes the temperature in the room to raise till it dissipates, even after heating has stopped. Set the thermostat heating 2 to 3 degrees below the preferred set point if you realise this situation.
3. The thermostat or its wires have been damaged and are not reliably signaling the heating system primary controller. For example, an internal relay sticks and keeps heat on even after the thermostat has sent a signal to shutdown heating.
4. The thermostat is being blocked from properly sensing room heat. That could be due to movement of the warm air supply registers to a new, more distant location, or more often, due to furniture, drapes, or even dust that blocks the air inlet openings around the thermostat that allow it to sense room temperature. This results in the thermostat wrongly sensing the temperature in the room.
5. The thermostat is located on a cold outdoor wall or where cold air blows on it. If your thermostat was not moved and is on an interior wall and in a draft of cold air, this isn't likely to be the cause of the problem you describe.
Some of the reasons why the thermostat fuse will blow or emit smoke are:
1. The voltage from the C terminal of your control board is higher than 35 VAC. Currently, the Degrii thermostat only supports voltages lower than 35 VAC and as such voltages equal and above 35 VAC will cause the fuse to blow.
2. A short circuit between Rc and C on the thermostat will also cause the fuse of the furnace to blow. This is a rare case caused in the manufacturing process.
3. The fuse of the furnace will blow if you mistakenly connect the RC wire to the Rc terminal and the C wire to the Rh terminal. Always make sure you are connecting the right wires to the right terminals.
4. Surge in voltage or erratic power outage can also result in the thermostat fuse blowing.
Under normal circumstances, a well installed thermostat will not cause the furnace fuse to blow. However, this may happen only if there is a short circuit between any of the wires and C. For example, if the W1 wire and the C wire are touching each other, then there will be a short circuit whenever the thermostat calls for heat, resulting in the fuse of the furnace blowing. To resolve this, check your wirings to ensure that you do not have any exposed wires touching each other.
Your temperature settings or schedule may change if there is a switch between states. Any state change (Home, Away, Sleep) during a schedule will result in the schedule being canceled. The Home-Away-Sleep temperature is the basic temperature setting of the thermostat and so changing states (Home, Away or Sleep) during a schedule will cancel the schedule at that particular time.
Go to Settings --> Advanced --> Safety Temperature and then select None for both Min and Max safety temperatures. Save the change and go to the thermostat main page, and select off under MODE to turn off the thermostat.
Use the App or online compatibility checker to check if you need a Degrii CWA.
Cases that may require C wire adapter installation or a C wire:
· During thermostat setup, the Degrii OS app tells you that you need the C wire adapter.
Note: If the app tells you that you do need the Degrii CWA during installation, you may need to exit set up until you have received the CWA. If you already have the CWA, proceed to installing the CWA by following the app instructions.
You can install the C wire adapter yourself. For a brief video of the installation process, go to How to install the Degrii CWA.Note: If your system doesn’t have a C terminal, you’ll need to call a pro.
1. Ensure that you have started the thermostat setup in the app and you have selected the wires of your old thermostat.
2. Make sure your HVAC system is still off and click Begin in the app to start the installation of the CWA.

3. Take a picture of your current control board wiring for future reference. Make sure you can see the terminal letters and identify the colour of the wires in the photo
4. Label the wires: To install the CWA, you will need to disconnect the 4 wires (Y, G, R and W) from the control board and connect them to the CWA. Label the wires Y, G, R, and W. Note, R can also be Rc.

5. Disconnect the labeled wires from the control board. You may need to loosen the screw holding the wire to the control board.

6. Connect the labeled wires from the control board to the CWA. Use the screwdriver to tighten the screw after inserting each wire to ensure it's securely connected

7. Connect the wires from the CWA to the control board. Match the wire to the control board terminal and make the connection. Make sure to tighten the screw.

8. Your done, replace any covers removed during the installation. With the CWA installed, you can now continue with the thermostat Installation Instructions.
·If your home has one thermostat, install the C wire adapter at the furnace or air handler.
-If there’s a control board, find the series of labeled terminals on it and install the C wire adapter there.
-If there’s no control board, which is common for heat-only systems, find the thermostat wiring and where it connects to the furnace.
·If you have a zoned system with more than one thermostat, install the C wire adapter at the zone controller. If you can’t locate your zone controller, contact a pro.
Use the App or online compatibility checker to check if you need a 24v power adapter. Cases that may require 24v power adapter or a C wire:
·During thermostat setup, the Degrii OS app tells you that you need the 24v power adapter.Note: If the app tells you that you do need the 24v adapter during installation, you may need to exit set up until you have received the 24v adapter. If you already have the 24v adapter, proceed to installing the adapter by following the app instructions.
You can install the 24v power adapter yourself.
1. Ensure that you have started the thermostat setup in the app and you have selected the wires of your old thermostat.
2. Make sure your HVAC system is still off and click Begin in the app to start the installation of the CWA.

3. Connect the 24v power adapter wires to the Rc and C terminals of the thermostat. If the Rc terminal already has a wire connected to it, merge the HVAC Rc wire with the 24v power adapter Rc wire and connect it to the thermostat Rc terminal.

4. Once you are done installing the 24v power adapter, connect the adapter to your power supply outlet on the wall and turn it on.
If your home has one thermostat, install the 24v power adapter at the thermostat terminals by connecting the wires to the Rc and C terminals of the thermostat.
Remote Thermostat
Degrii Remote Thermostat is a next-generation Smart Thermostat Sensor that detects both temperature and occupancy, and allows you to control the temperature in your room remotely without the use of the app.
They are built to supplement the temperature and occupancy control of the Degrii smart thermostat. Install them in your home for targeted comfort in the rooms that matter most (bedrooms, living room, etc.), and in rooms that get too hot or too cold for a more balanced temperature throughout the home.
There's no wrong way to use your Remote Thermostat.
Place it in a high-traffic room to detect occupancy to take advantage of Degrii Smart Features like Follow Me. They can be placed in areas that are either warmer or cooler than the rest of your home. Using the Remote Thermostat with your Degrii Smart thermostat can help you achieve a more balanced temperature throughout your home by minimizing hot or cold spots.
After pairing the remote thermostat with the Degrii smart thermostat, the Comfort State is set to both Home and Sleep by default. This is the State you will like the remote thermostat to participate in comfort control. For example, if you're putting a Remote Thermostat in your bedroom, but you don't spend a lot of time there when you're not sleeping, you can choose to have the bedroom Remote Thermostat only participate in the Sleep Comfort State. Doing so will ensure that your bedroom remains the temperature you like throughout the night. No more going to bed too hot or too cold!
In order to best detect occupancy changes, the best placement for a Remote Thermostat is about five feet off the ground in a location that's facing the entire room. Avoid locations that may have the sensor come into contact with any external factor that may influence its readings. These can include vents, fans, and direct sunlight.
Go to Degrii app thermostat home page > Click on the Remote Thermostat icon close to the Settings icon in the upper right corner.

On the Sensor list page, you will see the status of all the sensors you have available:

Ready to Pair
All remote thermostats that have not been paired yet are listed here. These devices can be paired to the Degrii smart thermostat by clicking on the discovered device to pair it. The maximum number of degrii remote thermostats that can be paired with the degrii smart thermostat is 12.
Active Thermostat
All devices participating in comfort control are listed here. The temperatures of these devices are averaged and used to provide optimal comfort for the home.
Inactive Thermostat
Devices that are not participating in comfort control are listed here. The temperatures of these devices are excluded and not averaged.
Offline
When the remote sensor is offline (probably because it is off), the room temperature and humidity appear blank as shown below.

1. Press and hold the - and + buttons together for 5 secs. All icons will be displayed on the screen to show that the device has been unpaired.
2. Release the buttons and check the Bluetooth icon to confirm that the device has been unpaired.
When a sensor isn't participating, it still reports the temperature to the thermostat, but the reading isn't used to help determine the average home temperature.
When a sensor loses connection from a Degrii thermostat, it will appear under MAIN MENU > SENSORS on your thermostat and in the app as a hollow sensor with no signal waves and with "N/A" showing underneath.

A sensor could lose connection from your Degrii thermostat if:
- The battery is low.
- It’s too far from your Degrii (more than 17 feet).
- There’s interference from environmental factors (walls, or other devices broadcasting on the same frequency, such as a baby monitor, cordless phone, etc.).
Yes, the Degrii Remote Thermostat can be used as a standalone temperature and humidity monitor.
Note: However, the Degrii Remote Thermostat cannot be used to control your HVAC (Heat/Cool) unless it is paired with the Degrii Smart thermostat.
