Johnson Controls TRUE RH HC-67x3 Installation Instructions Manual

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.
