Utility Scheduling
This feature can help reduce fuel or electric expenses by

utility charges rise. For example, the system can be set to raise
indoor temperature slightly in summer (or lower it in winter)
during hours of peak usage when rates are higher.
1. Press MENU, then press Preferences, then press Utility
Schedule Options.
