Installation Guide

Installation Considerations

The 17A30 zone sensor is a 12VDC low-voltage
device and requires a common wire to the damper
control module to operate.
• Shut off all power to system components before
installing zone sensor.
• Make sure that all wiring conforms to local
and national building and electrical codes and
ordinances.
• Never install the zone sensor on outside walls or
in direct sunlight.
• Use 2-pair, 18AWG unshielded thermostat cable
(field-provided) for power terminals (PWR and
C). Recommend using 2-pair 22AWG shielded
thermostat cable for communications terminals
(D+ and D-) which will help eliminate any noise
interference.
