Issued July 8, 2015
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
• 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.
