active

By default, this thermostat uses four adjustable ‘events’ on a 24 hour cycle. Each

event is a time of day requiring a room temperature change. This optimizes system

efficiency by reducing room temperatures when the building is less likely to be

occupied.

Although default schedule settings are

recommended, they are fully adjustable.

Please refer to the “Advanced Schedule

Settings” section on Page 9 for more

detailed settings.
