Wrong Values
•
Check the configuration. See
• Allow enough time for sensor transmissions.
NOTE:
Because the wireless sensors normally
transmit only several times per hour
to conserve power,
allow at least 30
minutes for transmissions to be received
and all the relevant object values to be
updated
when verifying normal operation.
Other Issues
• If an HPO-9001 distribution module is being
used on the controller, see the “Use of HPO-9001
Distribution Module” section in the
Series Gateways Installation Guide
.
• Contact KMC Controls for assistance.
MAINTENANCE
Careful installation will help ensure long-term
reliability and performance.
To maintain accurate temperature and humidity
sensing, remove dust as necessary from the
ventilation holes in the top and bottom of the
cover.
To clean the cover, use a soft, damp cloth (and
mild soap if necessary). Do not spray any liquids
on the cover.
Replace the optional lithium battery every three
years or as needed by actual use.*
*NOTE:
Factors that shorten battery life include:
• Installation in interior spaces with only
artificial light (which charges sensors
less efficiently than indirect daylight).
• Lengthy periods of darkness (which
increases the reliance on the battery).
• Adding setpoint adjustment or humidity
to a temperature sensor (which requires
more power).
• Frequent changes (beyond their respec-
tive thresholds) in measured tempera-
ture, humidity, or setpoint values (which
makes transmissions more frequent).
