IMPORTANT: The HL-67x5 Series Multi-function

Humidity Device is intended to
provide an input to equipment
under normal operating conditions.
Where failure or malfunction of the
HL-67x5 Device 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 HL-67x5 Device.

IMPORTANT: Le HL-67x5 Series Multi-function

Humidity Device est destiné à
transmettre des données entrantes
à un équipement dans des
conditions normales de
fonctionnement. Lorsqu'une
défaillance ou un
dysfonctionnement du HL-67x5
Device 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 HL-67x5
Device.

Parts Included

• HL-67N5-8N00P

• No. 8 x 1 in. Phillips-head sheet metal screw (2)

• washer for use with conduit fitting (conduit fitting

and nut not provided)

Tools Required

• hole saw with 1 in. (25 mm) diameter blade

• drill with 1/8 in. (3 mm) drill bit

• 1/8 in. (3 mm) flat-blade and No. 2 Phillips

screwdrivers

• pliers

• gasket, sealer, or other means to seal the area

between the unit and the duct

ocation Requirements

L

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.

When selecting a location for the HL-67N5-8N00P,
consider the following:

• Position: The HL-67N5-8N00P is designed for
duct mounting in any position, except with the
probe tip pointed up.

• Duct Diameter: Recommended minimum diameter
(round ducts) or width (square ducts) is 12 in.
(305 mm).

• Air Stratification (when the unit is mounted on the
discharge side of the fan): Recommended location
is at least 8 ft (2.4 m) downstream from
humidification equipment, where duct air and water
vapor are sufficiently mixed. Avoid areas where the
probe might be exposed to condensation.

The multi-function humidity device must be configured
prior to installation for the following: input and output
signals and setpoint and proportional band.

The HL-67N5-8N00P has a setpoint potentiometer
(adjustable from 60 to 95% Relative Humidity [RH]) and
a proportional band potentiometer (adjustable from 5 to
30% RH). Refer to Figure 1 to change the setpoint or
proportional band for the application desired.

b. If the HL-67x5 is used as a proportional

override device, refer to Table 1 for jumper
positions.
