Troubleshooting
• Be sure the 10,000 ohm pull-up resistors on the
controller board are selected/turned ON.
• Check wiring. To prevent excessive voltage drop,
use a conductor size that is adequate for the
wiring length!
• Check sensor conguration and tables in the
controller.
• Check voltage from the controller.
• Check that the sensor is mounted correctly. (See
the Mounting Considerations section above.)
Mounting Considerations
Depending on the application, space temperature
sensors generally should NOT be:
• Mounted on an exterior wall.
• Mounted on or near a large thermal mass (e.g.,
concrete block wall).
• Blocked from normal air circulation by obstruc-
tions.
• Exposed to heat sources (e.g., lights, computers,
copiers, or coee makers) or to sunlight (at any
time of the day).
• Exposed to drafts from windows, diusers, or
returns.
• Exposed to air ow through the conduit (from
leaks in plenum ducts)—put plumber’s puy,
painter’s puy, caulk, or other sealant inside the
conduit to block air ow.
Apply what is relevant to other applications (e.g.,
duct sensor).
Introduction
This document gives conguration, troubleshoot-
ing, and other related information for temperature
sensors using Type III thermistors. For mounting,
wiring, and specications, see the respective product
installation guide and data sheet (STE-1400 Series
Data Sheet for STE-14xx sensors).
