TouchPRO WirelessTM Thermostat
Model Number
LR-HWLV-HVAC* TouchPRO WirelessTThermostat
*Available in white.
Add LutronRComfort Controls to your light and
shade / drapery systems for convenient control of all
aspects of an environment—natural light, artificial light,
and temperature—from the touch of a button. LutronR
Comfort Controls allow heating and cooling systems to
integrate seamlessly with LutronRsystems and must be
located within 30 ft (9 m) of an RF signal repeater.
The TouchPRO WirelessTThermostat is designed
by Honeywell and utilizes LutronRClear ConnectR
technology. The TouchPRO WirelessTThermostat
installs like a conventional thermostat, and when used
with a seeTempTWall Display, it puts temperature
control and measurement where it makes sense.
In a RadioRAR2 or HomeWorksRQS system, the
TouchPRO WirelessTThermostat allows the ability to
adjust heating and cooling systems any time of the
day—even from your mobile device when you’re away
from home.
Press the “eco” button on the seeTempTWall Display
to trim HVAC settings automatically. The “eco” button
trim is controlled by RadioRAR2 and HomeWorksRQS
systems. The TouchPRO WirelessTThermostat can
only be used in systems that are programmed using
the PC Programming Tool.
The TouchPRO WirelessTThermostat is easy to use
and provides superior product quality and aesthetics.

TouchPRO WirelessTM Thermostat
TouchPRO WirelessTM Thermostat
•Wires to HVAC equipment.
•Uses RF to communicate with seeTempTWall
Displays, and other LutronRwireless devices.
•Requires 24 V~common connection from
the HVAC equipment or use of the included
wiring module. The wiring module can be
mounted easily on or near HVAC equipment
and is to be used when a 24 V~ common
connection is not available. For more
information, refer to the instructions included
with the wiring module.
seeTempTWall Display
•Designer style opening that can be ganged
with other devices like dimmers and keypads.
•Installs in a standard wallbox for low-profile
appearance.
•Celsius and Fahrenheit models available.
•Multiple seeTempTWall Displays can be
used to control one TouchPRO WirelessT
Thermostat from multiple locations.
•Pressing the “eco” button saves energy by
trimming the temperature a programmed
amount. Default is +/- 2 °F (1 °C).
•120 V~wiring requires hot and neutral wiring.
•24 V~wiring requires 24 V~and common
wiring from HVAC equipment transformer
or other 24 V~IEC PELV / NECRClass 2
transformer.
Design Features
Lutron®System Features
•7-day programmable schedule.
•Select alternate set points to save energy
when on vacation or away from home.
•System features are programmed in the
