Multi-Function Humidity Device HL-67N5 Series Johnson Controls

The HL-67N5 Multi-Function Humidity Device is intended to provide input to equipment under normal operating conditions.  The HL-67N5 regulates duct humidity by overriding a system controller’s demand for humidification when humidity exceeds a user-defined setpoint.

TRUERH offers patented circuitry and calibration
Multi-functional device with several humidity control applications: high limit or proportional override, stand-alone proportional or stand-alone two-position
All-plastic duct probe material improves thermal performance, and complies with Underwriters Laboratories® Inc (UL) flammability ratings for plenum use; complies with Blue Angel (Germany) and TCO'95 (Sweden) environmental regulations
All polymer humidity sensor provides patented sensing element for accurate and reliable humidity sensing with improved resistance to chemical corrosion
Humidity and temperature sensors in one unit eliminate need for separate sensors, reducing installation time and cost
Adjustable RH standpoint enables user to define duct’s maximum allowed humidity level, reducing excess humidification equipment cycling
