Installation
Temperature sensors use RJ12 jacks for easy connection to the RJ splitter. Use the supplied 4-way RJ
splitter or you can use the SENSORS port with couplers and splitters.

OUTDOOR Sensor
1.
Attach the ring of the TEMP-OUTDOOR with the supplied #6 sheet metal screw, or use any existing
post, hook or machine screw.
2.
Route the cable to the ARC Solo.
3.
Plug the connector of the TEMP-OUTDOOR into one of the four available input jacks on the RJ11
Splitter. If an extension cable is required, only the center two conductors of an RJ12 cable need to
be extended, corresponding to pins 3 and 4 on the RJ12 connector.

INDOOR Sensor
You can use the Burk 25’ 6
-conductor cable (part number SENSOR CABLE) to connect the sensor to the
ARC Solo. If a different cable is used, note that only two conductors are required, corresponding to pins
3 and 4 on the RJ12 connector. The cable must reverse the connections from one end to the other so
that pin 4 on the TEMP-INDOOR sensor connects to pin 3 on the ARC Solo splitter and pin 3 on the
TEMP-INDOOR sensor connects to pin 4 on the ARC Solo splitter.
1.
Secure the sensor in the desired location and connect an RJ12 cable.
2.
Route the cable to the ARC Solo splitter.
3.
Plug the connector of the TEMP-INDOOR into one of the four available input jacks on the splitter.
