Install Instructions

HE-69xx0NP Duct Probe Humidity Element with
Temperature Sensor Installation Guide
Installation
Important: Only use this HE-69xx0NP Humidity
Element with Temperature Sensor as an operating
control. Where failure or malfunction of the humidity
element with temperature sensor could lead
to personal injury or property damage to the
controlled equipment or other property, additional
precautions must be designed into the control
system. Incorporate and maintain other devices,
such as supervisory or alarm systems or safety or
limit controls, intended to warn of or protect against
failure or malfunction of the humidity element with
temperature sensor.
Important: Utiliser ce HE-69xx0NP Humidity Element
with Temperature Sensor uniquement en tant
que dispositif de contrôle de fonctionnement.
Lorsqu'une défaillance ou un dysfonctionnement du
humidity element with temperature sensor risque
de provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la
conception du système de contrôle doit intégrer des
dispositifs de protection supplémentaires. Veiller
dans ce cas à intégrer de façon permanente d'autres
dispositifs, tels que des systèmes de supervision
ou d'alarme, ou des dispositifs de sécurité ou de
limitation, ayant une fonction d'avertissement
ou de protection en cas de défaillance ou de
dysfonctionnement du humidity element with
temperature sensor.
Location requirements
Important: To avoid damage to the circuit board
and components, do not mount the unit in a location
where high concentrations of corrosive vapors are
present.
Place the Duct Probe Humidity Element in a location that
complies with these guidelines:
• Position: designed for duct mounting in any position,
except with the probe tip pointed up.
• Duct diameter: the minimum diameter for round ducts
is 12 in. (305 mm) and the minimum width for square
ducts is 12 in. (305 mm).
• For air stratification, when the unit is mounted on the
discharge side of the fan, ensure that the location is at
least 8 ft (2.4 m) downstream from the humidification
equipment, where duct air and water vapor are
sufficiently mixed. Avoid areas where the probe is
exposed to condensation.
Application setup
Before installation, configure the element for the required
output signal. See Figure 1 to set the output jumper for
the application.
