HE-6800 Series Humidity Transmitters with Temperature Sensor

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 RelativeHumidity (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.

Allows users to adjust the room comfort and choose occupancy features that match the application and transmitter.

Enables transmitter use in high input voltage applications.

Provides either a 0 to 5 VDC or 0 to 10 VDC output for compatibility with various controllers.

Displays the current operating mode of the controller (VMA12 and VMA14 Series only).

Overrides time-of-day scheduling when the space is occupied outside of normal occupied hours schedule.

Allows for minor temperature adjustments from the setpoint.

Product overview

A manual override PB allows the occupant to control the space temperature. This feature allows the end user to signal the controller that the space is occupied after hours or on weekends.

An LED is standard for all models. When used with a VMA12 or VMA14 Series Controller, the green LED displays the current operating mode of that controller: On = Occupied, Off = Unoccupied, andFlashing = Standby.

The controller compatibility DIP switch programs the HE-6800 Series Humidity Transmitter to:

• disable the PB and LED indicator

• enable the PB with LED indicator

• enable the PB without LED indicator The DIP switch matches the PB and LED indication with

features recognized by more recent Johnson Controls controllers. Specifically, the DIP switch allows for matching controller features to disable the occupancy LED and/or PB.

The HE-6800 Series Humidity Transmitter also features a 0 to 10 VDC or 0 to 5 VDC selector DIP switch and a power supply selection DIP switch. The VDC output selector switch enables you to change the output for % RH. The power supply DIP switch enables you to use the

HE-68xx-xN00WS

transmitter in high input voltage applications (such as 24 VAC).

The HE-6800 Series Humidity Transmitter has terminal block wiring connections, and includes a selection of a 1000-ohm nickel, 1000-ohm platinum, or 10,000-ohm thermistor temperature sensing element. The unit can be used with Application Specific Controllers (ASCs) or for universal applications.

Important: The HE-6800 Series Humidity Transmitter and Temperature Sensor is intended to provide an 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.
