HE-6800 Series Humidity Transmitters with
Temperature Sensor Installation Guide
Applications
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 andLight-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.
Important:
Use the HE-6800 Series Humidity
Transmitter only to provide input to equipment
under normal operating conditions. Where failure
or malfunction of the transmitter could lead
to personal injury or property damage to the
controlled equipment or other property, additional
precautions must be designed into the control
system. Incorporate and maintain other devices,
such as supervisory or alarm systems or safety or
limit controls, intended to warn of or protect against
failure or malfunction of the transmitter. Approved
