a schedule is
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.
Mode of Operation
The 510 thermostat has two modes of operation:
Off: Does not provide heating.
Heat: Provides heating only.

Auto: Automatically switches between heating and cooling the space. Note: If a
floor (Slab) sensor is installed, the floor minimum temperature will be maintained
even during cooling.
Cool: Provides cooling only. Note: If a floor (Slab) sensor is installed, the Slab
minimum temperature will be ignored.
