MODEL
Wiring Requirements
The attached 20’ of plenum rated cable should be adequate for many installations. If the cable needs to be
extended, we recommend no more than one additional segment of wire be spliced onto the 20’ leads. Please
use 18 - 22 gauge 2 conductor unshielded thermostat wire. Wire length not to exceed 200 feet.
IMPORTANT: Do not run sensor wiring in the same conduit as the 24VAC thermostat wiring. Electrical
interference may cause the sensor to give incorrect temperature readings. Keep wiring at least two feet away
from motors, lighting ballasts, other line-voltage circuits.
NOTE: All sensor wiring must be in compliance with all applicable local and national codes.
SAFETY CONSIDERATIONS
Read and follow the manufacturer instructions carefully. All wiring must conform to local and national
electrical codes. Improper wiring or installation may damage the sensor.
Recognize safety information. This is the safety alert symbol . When the safety alert symbol is present on
equipment or in the instruction manual, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety alert
symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death.
WARNING signifies a hazard which could result in personal injury or death. CAUTION is used to identify
unsafe practices which may result in minor personal injury or property damage.
The ACC-DSEN Air Temperature Sensor measures air temperature with a range of -40 to 131 F. This sensor
may be used as a Remote Sensor, a Supply Air Sensor, or a Return Air Sensor.

Sensor Wiring
The connection between the Air Temperature
Sensor and the thermostat must be wired per the
connection diagram. Only two conductors are
used, therefore the extra conductors should be cut
from each end of the cable to prevent shorting.
Follow the color coding as shown.
WARNING
Turn off power to the thermostat before wiring. Death
or injury from electric shock could result.
