NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Important note: To comply with the FCC RF exposure compliance
requirements, no change to the antenna or the device is permitted.
Any change to the antenna or the device could result in the device
exceeding the RF exposure requirements and void user ’s authority to
operate the device.
This Class B digital apparatus complies with ICES-005 of Canada.

ALC2-R
OVERVIEW
The ALC2-R 2-Channel controller allows for each channel to be
independently controlled via schedule, sensor, or combination of the
technologies to provide even greater energy savings. Each channel can
be configured to work as either 0-10 VDC for dimming applications, or
as ON/OFF for plug load or other non-dimming application needs. These
settings will be available via the ARISTA app.

INSTALLATION (SEE WARNINGS BEFORE INSTALLING)
1. Determine mounting location.
2. Determine and remove proper knockouts for installation.
3. Install proper fittings for installation adhering to all local codes.
4. Connect all input and output wiring (See wiring diagrams for examples).
a. Be sure to keep all Class 1 and Class 2 wiring separated.
5. Install the included antenna.
6. Turn power ON to the controlling circuit.
7. Verify blue LED is flashing and all connected loads are ON.
a. Green Load indicators and loads should turn ON and OFF by manual button presses.
8. Refer to programming instructions.
NOTE: For Programming instructions please visit www.Intermatic.com. The ARISTA App is available on Apple App and Google Play stores.
