AHU COMMUNICATIONS KIT INSTALLATION
Thermistor Installation
Attaching the Pipe Thermistors
Thermistors must be securely attached with a pipe strap� The equip-
ment will not operate properly if thermistors are not making good
physical contact in the appropriate installation location�
1. Securely attach the thermistor to the pipe with a field-supplied
pipe strap.
2. Insulate the thermistor with a field-supplied insulation sheet that
is >5t.
Tips for Attaching the Pipe In / Pipe Out Thermistors
• Put the thermistor cable in a separate protective tube.
• Always add a pull-relief to the thermistor cable to avoid strain on
the thermistor cable and loosening of the thermistor. Strain on the
thermistor cable or loosening of the thermistor can result in bad
contact with the pipe and incorrect temperature measurement.
• To avoid water accumulating on the thermistor tip, position
the thermistor cable slightly below the thermistor tip, or
install the thermistor tip parallel with the cable.
Do not include a 90° angle or a kink in the thermistor
cable, nor install the thermistor tip upside down.
