HC-67x3 Humidity Controllers
Application Requirements
The HC-67x3 Humidity Controllers proportionally
ramp their output as the humidity changes in the
proportional band. The setpoint is at the low end of
the proportional band for Direct Acting (DA) and at
the high end for Reverse Acting (RA) (shown in
Figure 1) for both wall mount and duct probe
humidity controllers.

Installation
IMPORTANT:
The HC-67x3 Series Humidity
Controllers is intended to provide an input to
equipment under normal operating conditions. Where
failure or malfunction of the HC-67x3 Series Humidity
Controllers 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 HC-67x3 Series
Humidity Controllers.
IMPORTANT:
Le HC-67x3 Series Humidity
Controllers est destiné à transmettre des données
entrantes à un équipement dans des conditions
normales de fonctionnement. Lorsqu'une défaillance
ou un dysfonctionnement du HC-67x3 Series Humidity
Controllers 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 HC-67x3 Series Humidity
Controllers.
The controller is available in both a wall mount or duct
probe package to suit a variety of sensing application
needs. Refer to the
Mounting
section for a complete list
of the tools required for installation.
