HE-6800 Series Humidity Transmitters with Temperature Sensor
Description
The HE-6800 Series Humidity Transmitters with Temperature Sensor provide both humidity and temperature sensing in room wall-mount applications. The transmitter offers local warmer/cooler temperature setpoint adjustment and temporary occupancy override. The humidity sensor provides Relative Humidity (RH) accuracy of ±2% or ±3% RH and measures RH over the entire range of 0 to 100%.
A warmer/cooler dial is included on certain models for minor temperature adjustments from the setpoint. All models feature an occupancy override button that allows the user to override time-of-day scheduling when the space is occupied outside of the normal occupied hours schedule. The transmitter also includes DIP switches to enable or disable override and Light-Emitting Diode (LED) functions. In addition, all models feature a user-selectable 0 to 5 VDC or
0 to 10 VDC humidity output switch, and a power supply selection switch.
The HE-6800 Series Humidity Transmitters include screw terminal block terminations that provide flexibility for field wiring. All models include a 6-pin modular jack access port for connecting accessories to the Zone Bus. This feature allows a technician to commission or service the controller via the transmitter.
Features
•controller configuration DIP switch — allows users to adjust the room comfort and choose occupancy features that match the application and transmitter
•power supply selection switch — enables transmitter use in high input voltage applications
•user-selectable humidity output — provides either a 0 to 5 VDC or 0 to 10 VDC output for compatibility with various controllers
HE-6800 Series Humidity Transmitters with Temperature Sensor
•occupancy Light-Emitting Diode (LED) indicator — displays the current operating mode of the controller (VMA12 and VMA14 Series only)
•manual override pushbutton (PB) — overrides time-of-day scheduling when the space is occupied outside of the normal occupied hours schedule
•warmer/cooler setpoint dial (select models) — allows for minor temperature adjustments from the setpoint
Repair Information
If the HE-6800 Series Humidity Transmitter fails to operate within its specifications, replace the unit. For a replacement transmitter, contact the nearest Johnson Controls® representative.
