Description
The HC-67x3 Series TRUERH™ Humidity
Controllers come in both wall or duct mount
packages. These attractively styled
controllers offer ease of installation and
application flexibility. The patented
All-Polymer™ humidity sensor construction
improves resistance to chemical corrosion.
The HC-67x3 functions as a proportional
humidity controller.
The output is jumper-selectable Reverse
Acting (RA) or Direct Acting (DA), along with
an adjustable setpoint and proportional band.
Refer to the HC-67x3 Series T
Humidity Controllers Product Bulletin
(LIT-216265) for important product application
information.
