✔ Level (to mount correctly)
3.2 Installation Steps
Step 1: Turn Off Power
✔ Switch off the power to your HVAC system at the circuit breaker to prevent electrical shock.
Step 2: Remove the Old Thermostat
✔ Unscrew and carefully disconnect the wires from the old unit.
✔ Take a photo of the wire connections for reference.
Step 3: Mount the New Thermostat
✔ Use the provided mounting plate and secure it with screws.
✔ Ensure the thermostat is level for accurate readings.
Step 4: Connect the Wires
✔ Match the labeled wires from your HVAC system to the thermostat’s terminals.
✔ Most common labels:
- R (Red) – Power
- W (White) – Heat
- Y (Yellow) – Cooling
- G (Green) – Fan
Step 5: Turn Power Back On & Test
✔ Restore power and test settings to ensure proper function.
✔ Follow the setup instructions on the thermostat’s screen or app.
4. Best Temperature Settings for Maximum Savings
Setting the right temperatures can maximize energy efficiency.
4.1 Recommended Settings by Season
| Time of Day | Winter (°F) | Summer (°F) |
|---|---|---|
| Wake Up | 68°F | 78°F |
| Away from Home | 60-65°F | 85°F |
| Evening | 68-70°F | 78°F |
| Sleeping | 60-65°F | 78°F |
4.2 Tips for Maximizing Efficiency
✔ Lower the heat at night – Sleeping in a cool environment improves sleep quality.
✔ Raise AC temperature when away – Avoid cooling an empty home.
✔ Use programmable settings – Customize based on work and weekend schedules.
