Night usage is often long and continuous. Without settings, AC may overcool and waste units while you sleep.
Most people sleep better in stable conditions, not very cold conditions. Sleep mode helps keep comfort steady with lower power draw in late hours.
Sleep Strategy
- Start at a comfortable setting.
- Use sleep mode to gradually raise by 1-2C.
- Set timer near early morning.
Comparison
| Mode | Runtime | Cost |
