Scene	Description	Thermostat Operation
1	Permanent 1	Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away
2	Permanent Away 2	Away DHW demands are ignored (applies to reset modules) Setpoint demands operate (applies to reset modules)
3	Permanent Unoccupied 3	Unoccupied
4	Permanent 4	The scheduled event, Wake, Unoccupied, Occupied, Sleep, Away
5	Permanent 5	Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away
6	Temporary Occupied 6	Occupied for 3 hours
