Tools Required for Installation
Before you begin installing your Sensi thermostat, it’s essential to gather all the necessary tools to ensure a smooth and efficient process. Having the right tools readily available will prevent delays and potential frustration during the installation.
First and foremost, you’ll need a screwdriver. A multi-bit screwdriver with both Phillips head and flathead bits is ideal, as thermostat wiring often uses both types of screws. Ensure the screwdriver is properly sized to avoid stripping the screw heads. A small level is also crucial for ensuring that your thermostat is mounted straight on the wall, providing a professional and aesthetically pleasing finish. Most Sensi thermostats have a built-in level.
A wire stripper is necessary for safely removing the insulation from the thermostat wires without damaging the copper conductor. A pair of needle-nose pliers can be helpful for bending or straightening wires, especially in tight spaces. You may also need a pencil for marking the wall where you intend to mount the thermostat.
For safety, it’s essential to have a non-contact voltage tester to verify that the power to your HVAC system is turned off before working with the wiring. Additionally, consider having a small flashlight or headlamp to illuminate the wiring area, particularly if it’s dimly lit. Finally, have some wire labels on hand to mark the wires as you disconnect them from your old thermostat. This will greatly simplify the wiring process with your new Sensi thermostat.
Wiring Instructions Using the Sensi App
The Sensi app is your primary guide for wiring your new Sensi thermostat. It provides step-by-step instructions tailored to your specific HVAC system, making the wiring process straightforward and minimizing the risk of errors. Before you begin, ensure you have downloaded the Sensi app and created an account.
The app will first ask you to identify your existing thermostat wiring configuration. It will guide you through taking a picture of your current wiring setup. The app will then provide a wiring diagram that matches your system, showing you exactly which wires to connect to which terminals on the Sensi thermostat baseplate.
Before disconnecting any wires from your old thermostat, use the Sensi app to take a photo of your existing wiring. This photo will serve as a reference point should you need to double-check your connections later. As you disconnect each wire from the old thermostat, use the included wire labels to mark each wire with its corresponding terminal designation (e.g., R, W, Y, G). This is a crucial step to prevent confusion during the rewiring process.
Follow the wiring diagram provided in the Sensi app to connect each labeled wire to the appropriate terminal on the Sensi thermostat baseplate. Ensure that the wires are securely inserted into the terminals and that no bare wire is exposed. Once all the wires are connected, carefully attach the Sensi thermostat to the baseplate. The app will then guide you through the remaining steps of the installation process.
Common Wire (C-Wire) Requirement
A common wire, often called a C-wire, is frequently required for the Sensi thermostat to function correctly, particularly in systems that don’t provide constant power to the thermostat. The C-wire provides a continuous power supply from your HVAC system to the thermostat, which is essential for the thermostat to maintain its Wi-Fi connection and operate its advanced features.
Many older homes may not have a C-wire readily available. If your existing thermostat wiring doesn’t include a wire connected to the “C” terminal, you’ll need to address this before installing your Sensi thermostat. The Sensi app will guide you through identifying whether you have a C-wire or not.
If you lack a C-wire, there are a couple of options. One option is to install a new thermostat cable with an additional wire that can be used as the C-wire. Another option is to use a C-wire adapter, which allows you to repurpose an existing unused wire (typically the G wire, used for the fan) as the C-wire. Emerson offers a Common Wire Kit that simplifies this process.
The Sensi website provides detailed instructions and videos on how to install a C-wire using the Emerson Common Wire Kit. This kit typically involves connecting the adapter to your furnace control board and then connecting the repurposed wire to the C terminal on both the adapter and the Sensi thermostat. Always turn off the power to your HVAC system before working with any wiring.
RC/RH Jumper Information
The RC and RH terminals on a thermostat are related to the power supply for heating and cooling systems. In some systems, a jumper wire connects these two terminals, indicating a single transformer system. Other systems, known as two-transformer systems, have separate power supplies for heating and cooling, and therefore do not require a jumper wire.
The Sensi thermostat is designed to be compatible with both single and two-transformer systems. Fortunately, Sensi thermostats have a built-in RC/RH jumper, eliminating the need for you to manually install a jumper wire in most cases. This simplifies the installation process and reduces the risk of incorrect wiring.
If you have separate wires connected to both the RC and RH terminals on your existing thermostat, it signifies that you have a two-transformer system. In this scenario, you should leave the existing wires connected to the RC and RH terminals on the Sensi thermostat. Do not attempt to install a jumper wire.
However, if your existing thermostat has a jumper wire connecting RC and RH, and only one wire connected to either RC or RH, you should remove the jumper wire before installing the Sensi thermostat. The Sensi’s internal jumper will handle the connection automatically. The Sensi app will guide you through this process, ensuring proper configuration based on your specific wiring setup. Following the app’s instructions is crucial for preventing damage to your HVAC system or the thermostat itself.
