Advanced Programming Strategies

Overnight Pre-Cooling (10 PM - 6 AM):

• Set to 76°F when electricity is cheapest
• Your home becomes a "thermal battery"
• Saves $30-40/month on time-of-use plans

Morning Coast (6 AM - 2 PM):

• Gradually rise to 78°F
• Use fans for comfort
• Minimize AC cycling

Peak Avoidance (2 PM - 7 PM):

• Allow drift to 80-82°F
• This is where biggest savings occur
• AC runs minimally during highest rates

Evening Recovery (7 PM - 10 PM):

• Return to 78°F comfort
• Gradual cooling prevents system strain

Texas Reality: 78°F at 45% humidity feels like 72°F at 60% humidity

Smart Dehumidification:

• Enable "Cool to Dry" or similar feature
• Set humidity target to 45-50%
• AC runs strategically for moisture removal
• Comfort improves without lowering temperature
