How to Set Up a Smart Home: Smart Thermostat Install

Tech architecture infographic titled "Smart Thermostat Install" — HOW-IT-WORKS adapted as a house floor plan with devices. Create a clean top-down house floor plan showing key rooms and HVAC-related components connected with arrows to explain installation and setup of a smart thermostat. Render labeled boxes and callouts for each component with a simple generic icon, a canonical English name, and a one-line English role description. Include: 1) Existing Thermostat — "Wall controller" — "Reads temperature and sends HVAC commands"; 2) HVAC System — "Furnace / Air Handler" — "Heats or circulates air through the home"; 3) AC Condenser — "Cooling unit" — "Provides cooling when thermostat calls for AC"; 4) C-Wire / Power Wire — "24V common" — "Supplies continuous power to the smart thermostat"; 5) Smart Thermostat — "Wi-Fi thermostat" — "Controls heating and cooling and connects to the network"; 6) Home Wi-Fi Router — "Wireless network" — "Provides local network and internet access"; 7) Mobile App — "Phone setup app" — "Used to pair, configure, and monitor the thermostat"; 8) Cloud Service — "Remote access service" — "Syncs settings and enables remote control"; 9) Temperature Sensor — "Room sensor" — "Measures room temperature for smarter scheduling". Show arrows with short English labels describing what crosses: "24V power", "R/W/Y/G control signal", "cooling call", "heating call", "Wi-Fi setup", "HTTPS API", "device pairing", "temperature reading", "schedule update", "status sync". Make the flow technically accurate: thermostat wiring to HVAC control board with R, C, W, Y, G terminals; router connection via Wi-Fi; mobile app communicates to cloud service over HTTPS; cloud service syncs settings to thermostat; sensor sends room temperature data to thermostat. Add a numbered legend (1-7) in English walking through the lifecycle: 1. Turn off HVAC power at breaker for safety. 2. Remove the existing thermostat and label wires by terminal. 3. Check for C-wire availability and connect wiring to the smart thermostat base. 4. Mount the smart thermostat and restore power. 5. Connect the thermostat to the home Wi-Fi network using the mobile app. 6. Sync with the cloud service and configure schedule, heating, and cooling preferences. 7. Test heating, cooling, and room temperature readings to confirm correct operation. Visual style: minimal flat, editorial developer-blog illustration, isometric or flat tech-diagram style, vector-clean infographic layout. Use a minimal monochrome palette with soft grayscale tones, subtle contrast, thin clean lines, uncluttered spacing, calm modern mood, generic smart-home icons only, no real brand logos. The overall composition should feel like a precise setup guide combined with a technical architecture explainer, optimized for search intent around how to set up a smart home, but all visible text remains focused on smart thermostat installation. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real cloud-vendor logos (AWS / GCP / Azure) — use generic cloud icons, no watermarks No real smart home brand logos (no Google Home / Alexa / HomePod). Generic icons.
