The Sensi Touch 2 Smart Thermostat is a Wi-Fi enabled device designed to manage your home's heating and cooling system, offering remote control and smart features through a dedicated mobile application. This installation guide outlines the process of setting up the thermostat, from initial download of the Sensi app to connecting it to your home's Wi-Fi network and configuring its settings.
Function Description
The Sensi Touch 2 Smart Thermostat serves as a central control unit for your HVAC system. Its primary function is to regulate the temperature in your home, providing both heating and cooling capabilities. As a smart thermostat, it connects to your home's Wi-Fi network, allowing you to control and monitor your HVAC system remotely via the Sensi app on your smartphone or tablet. This remote access enables you to adjust temperature settings, create schedules, and receive alerts, enhancing comfort and potentially saving energy. The device is compatible with various HVAC system types, including gas, electric, boiler/radiant, and heat pump systems, and requires a common wire (c-wire) for power.
Usage Features
The Sensi Touch 2 Smart Thermostat offers a range of features designed for ease of use and comprehensive control:
- Remote Control via Sensi App: The core of the Sensi Touch 2 experience is its mobile application, available for download on both the App Store and Google Play. After creating an account and registering your thermostat, you can access all its features from anywhere with an internet connection. This includes adjusting the set temperature, changing system modes (heat, cool, auto, off), and managing fan settings.
- Step-by-Step Installation Guide: The Sensi app provides a detailed, step-by-step walkthrough for installation. This guide helps users identify their existing wiring, label wires correctly, remove the old thermostat, and install the new Sensi baseplate. It also assists in connecting the wires to the appropriate terminals and attaching the thermostat cover. For DIY installations, the "Not Mounted" option in the app ensures a thorough wiring and configuration process.
- Wi-Fi Connectivity: The thermostat connects to your home's 2.4GHz Wi-Fi network. The app guides you through the Wi-Fi setup process, which involves pressing "Menu" and "Wi-Fi" on the thermostat, then scanning a QR code or manually entering a security PIN from the thermostat screen into the app. This Bluetooth-assisted connection simplifies the pairing process.
- HVAC System Configuration: During installation, the app prompts you to select your furnace type (gas, electric, boiler/radiant) and identify the wires connected to your old thermostat. This information is crucial for correctly configuring the Sensi Touch 2 to work with your specific HVAC system. The app also helps you identify if you have a valid wiring configuration and provides resources for compatibility checks.
- Jumper Wire Management: The Sensi Touch 2 has a built-in jumper wire, eliminating the need to transfer jumper wires from your old thermostat. The installation guide explicitly instructs users to remove and discard any jumper wires found on the old unit.
- C-Wire Requirement: The Sensi Touch 2 Smart Thermostat requires a c-wire for continuous power. The installation process emphasizes this requirement, and troubleshooting tips are provided if the thermostat does not power on, often pointing to a c-wire connection issue.
- Thermostat Naming: After successful Wi-Fi connection, you can personalize your thermostat by selecting a name from suggested options (e.g., "Sensi," "Thermostat," "Downstairs," "Upstairs") or creating a custom name.
- Registration: The app guides you through registering your thermostat, allowing you to use the "Locate Me" option for automatic address entry or manually input your street address, city, state, ZIP code, country, and time zone.
- Contractor Information (Optional): If a professional contractor installed your thermostat and is a registered Sensi partner, they have the option to input their phone number during the setup process.
- Multi-Thermostat Management: For homes with multiple Sensi thermostats, the app allows you to add additional units by tapping the plus (+) sign on the main screen, enabling centralized control of all registered thermostats from a single account.
- Account Information Access: Users can manage their email preferences and update account information, including the associated email address and password, within the "Account" section of the app.
- HVAC Configuration Menu Reference: The manual includes a detailed chart of HVAC configuration menu items, descriptions, and options (e.g., Outdoor Equipment, Indoor Equipment, Reversing Valve Position, Humidifier, Dehumidifier). This reference helps users understand and verify their thermostat's settings for optimal performance.
Maintenance Features
While the Sensi Touch 2 Smart Thermostat is designed for minimal physical maintenance, its smart features contribute to system upkeep and troubleshooting:
