Important Notes
Environment
HVAC Controller:
Ambient operating temperature: 32 °F to 160 °F (0 °C to 71 °C), 0% to 90%
humidity, non-condensing. Indoor use only.
Codes
Install in accordance with all local and national electrical codes.
Cleaning
To clean, wipe with a clean damp cloth. DO NOT use any chemical cleaning
solutions.
RF Device Placement
The Receiver must be within 30 ft (9 m) of an RF signal repeater.
Installation of an HVAC Controller
HVAC Controller should be installed by a climate control
specialist.
1. Find a suitable location for the HVAC Controller near an HVAC system and
within 30 ft (9 m) of a repeater.
2. Mount vertically or horizontally, as shown in the Mounting Diagram, using
two #6 (M3) screws (included). When mounting, allow 7 in (177.8 mm)
clearance for the antenna and ensure convenient access to the contact
closures and front buttons. In order to achieve proper RF performance, do
not mount unit in a metal enclosure.
Programming
After installation, the HVAC controller (LR-HVAC) will only function when
programmed to a system with a seeTemp™ Wall Display (LRD-WST). For
full functionality, the HVAC Controller must be programmed to a RadioRA® 2
Main Repeater (RR-MAIN-REP) and PC software must be used by a Lutron
factory-trained installer. For questions on how to become a qualified installer,
please contact your local Lutron representative.
Temporary Programming
Since the HVAC system may need to function before a Lutron factory-
trained installer is available for programming, temporary programming may
be used to provide climate control.
To complete the steps below, the following are required: RadioRA 2 Main
Repeater (RR-MAIN-REP) within 30 ft of the HVAC controller, seeTemp
unit(s), and Wireless Temperature sensor(s).
1. Enter Add Mode: Press and hold the “Add” button on Main Repeater for 3
seconds until green “Add” LED begins to rapid-flash (ten times per second)
and repeater beeps. Wait 10 seconds.
2. Add the devices to the Main Repeater:
a. For the HVAC controller, press and hold the Link button for 3 seconds
until all LEDs normal-flash (once per second).
b. For the seeTemp, press and hold the Eco button for 3 seconds until all
LEDs normal-flash (once per second).
c. For the Wireless Temperature Sensor, press and hold the Link button for
6 seconds until the hidden LED flashes (once per second).
3. Exit Add Mode: Press and hold the “Add” button on any Repeater for 3
seconds until “Add” LED begins to rapid-flash. After LED turns off (can take
up to 30–60 seconds), system has exited Add Mode.
4. Test the system:
a. Set the seeTemp to Heat or Cool mode.
b. Tap the link button on the Wireless Temperature Sensor. The
Temperature will update on the seeTemp.
c. As the temperature changes, the HVAC controller will control the HVAC
equipment when required.
* Typical Power Consumption test conditions: two LEDs on.
Troubleshooting Guide for HVAC Controller
Returning an HVAC Controller to Factory Settings
Note: Returning the HVAC Controller to factory settings will erase all system
programming from the HVAC Controller and will require the HVAC Controller
to be reprogrammed into a system.
1. Triple tap and hold either button on an HVAC Controller. DO NOT release the
button after the third tap.
2. Keep the button pressed on the third tap until the LED(s) start to flash slowly
(approximately 3 seconds).
3. Release the button and immediately triple tap it again. The LEDs will flash
quickly. When the LEDs stop flashing, the HVAC Controller has been returned
to factory settings.

HVAC Controller
HVAC Controller Diagnostic Mode
The diagnostic mode is used to ensure the relays on the
HVAC controller are functioning and wired properly to
your HVAC system.
Follow the steps below to test your wiring using
diagnostic mode. There are three Diagnostic Mode
tests. The test that is cycled is determined by the 2
dipswitches on the HVAC Controller. The dipswitches
define whether the HVAC system is used with a
Conventional system or a Heat Pump system.
1. Enter HVAC Diagnostic Mode
Press and hold “Test” button for 10 seconds to enter Diagnostic Mode until
“Test” LED flashes rapidly. “Test” LED will flash slowly while in Diagnostic Mode.
2. Cycle through the test steps
The dipswitch settings determine which test cycle will be run. Tap the “Test”
button to advance through the diagnostic steps. Use the tables below to
determine the test sequence that will be run on your system. Each tap moves
the HVAC controller to the next step and will turn on and off different relays
and corresponding LEDS. At each step, the thermostat wiring can be verified.
NOTE: There is a 20 second minimum delay between each step.
3. Exit HVAC Diagnostic Mode
At any time, press and hold “Test” button for 10 seconds to exit Diagnostic
Mode. If no button is pressed for 3 minutes, the HVAC Controller will exit
Diagnostic Mode.
