Lutron Thermostat Controls
Lutron Thermostat Controls are the perfect
complement to light and shade / drapery
systems. Add Lutron Thermostat Controls
to your light and shade / drapery systems
for convenient control of all aspects of an
environment - lights, shades / draperies, and
temperature - from the touch of a button. Lutron
Thermostat Controls allow heating and cooling
systems to integrate seamlessly with Lutron
systems and must be located within 30 ft (9 m)
of an RF signal repeater.
Lutron Thermostat Controls put temperature
control and measurement where it makes
sense and allows the ability to adjust heating
and cooling systems any time of the day - even
when you’re away from home.
HVAC Controller
Lutron Thermostat Controls help optimize
energy savings without complicated
programming. Conveniently press the “eco”
button to trim HVAC settings automatically. The
“eco” button trim is controlled by RadioRA® 2
systems.
Lutron Thermostat Controls are easy to use and
provide superior product quality and aesthetics.
