HE-68N2-0N00WS Johnson Controls Humidity Element

Overview

The Johnson Controls HE-68N2-0N00WS is a room wall-mount humidity transmitter from the HE-6800 Series that integrates both relative humidity and temperature sensing into a single device. Housed in a compact white thermoplastic enclosure, it features a 1,000-ohm thin-film nickel sensing element for temperature and a capacitive polymer sensor that offers ±2% relative humidity accuracy. This model is engineered to provide precise environmental data for commercial building automation systems without local temperature setpoint adjustment dials.

Features

• Combines humidity and temperature sensing in one low-profile wall-mount enclosure.
• High-accuracy capacitive polymer humidity sensor provides ±2% RH precision across a 0 to 100% range.
• Integrates a 1,000-ohm thin-film nickel temperature sensing element for stable thermal monitoring.
• Temporary manual occupancy override pushbutton lets occupants suspend pre-programmed time-of-day HVAC schedules.
• DIP switches allow for quick on-site customization of controller settings and override functions.
• User-selectable analog humidity output switch toggles between 0-5 VDC and 0-10 VDC to match various system controllers.
• Power supply selection switch enables versatile operations in standard or high input voltage installations.
• Built-in 6-pin modular jack access port allows technicians to commission and service the network controller directly through the Zone Bus.
