as follows:
WARNING
Warning alerts you to a serious hazard. If you do not read and
follow
instructions very carefully at this point, there is a risk of injury or even
death.
CAUTION
Caution warns you of a potential hazard. If you do not read and follow
instructions carefully at this point, the product could be damaged or

CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features and options of the HMDW80 series
transmitters.
Introduction to HMDW80 Series
Vaisala INTERCAP®Humidity and Temperature Transmitter Series
HMDW80 measure relative humidity and temperature in various building
automation applications. Transmitters combine easy installation and
reliable operation with a low requirement for maintenance.
HMDW80 series includes transmitters for wall and duct mounting,
humid areas, and for outdoor installation. It also includes temperature-
only transmitters and transmitters with an optional display. Calculated
humidity parameters – dewpoint, wet bulb temperature, and enthalpy –
are also available.
HMDW80 series transmitters require minimal maintenance thanks to
their excellent sensor stability and high-quality materials. If necessary,
the INTERCAP®humidity sensor can be easily exchanged in the field
with practically no downtime.
Features provided by transmitters in the HMDW80 series:
- ±3.0 %RH accuracy.
- 0 ... 100 %RH measurement range.
- User exchangeable INTERCAP®humidity sensor for easy field
replacement.
- Several output parameters; see HMDW80 Series Transmitter Models
on page 11 for list of supported parameters by transmitter model.
- Several IP65-classified models for demanding HVAC applications.
- UL-V0 flammability rating.

Display
Display is present on the following models:
- HMD82D and HMD83D
- HMW88D and HMW89D
When the transmitter is powered on, it displays a sequence of
information screens about the transmitter and its analog outputs.
The screens are shown for a few seconds each. Checking the screens on
startup is a good way to verify that the transmitter’s configuration DIP
switches are set correctly.

After the startup screens have been displayed, the transmitter will show
the measurement screen.

If one of the transmitter’s error states is active, a notification symbol and
error text will appear on the screen. Depending on the error, the affected
measurement readings may be replaced by asterisks “*”. For more
information on the possible errors, see section Error Messages on the
Display on page 41.

Chapter 2 ___________________________________________________________Product Overview
VAISALA________________________________________________________________________ 17
Analog Output Overrange Behavior
Analog outputs of the HMDW80 series transmitters have a defined
behavior when the values measured by the transmitter are outside the
scaled analog output range:
- Output is clipped at the end of the range.
- Output is set to error state when measured value is 5% outside the
scaled range. See section Analog Output Error State on page 41.
- Output resumes normal function when measured value is back on the
scaled range.
NOTE
HMW82/83 and TMW82/83 transmitters are different from the rest of
the HMDW80 series. Their
analog output is clipped at 10% outside the
scaled range, and their analog outputs enter the error state when the
measured value is 20% outside the range.
For example, consider the temperature output of the HMD82 transmitter.
The output is 4 ... 20 mA, scaled to -40 ... +60 °C (-40 ... +140 °F).
- When measured temperature rises above +60 °C (+140 °F), the output
rises to 20 mA and stops rising even if temperature rises further.
- If the temperature rises above +65 °C (+149 °F), the output enters the
error state of 3.6 mA.
NOTE
This overrange
behavior does not mean there is a problem with the
measurements, and it does not affect the readings shown on the display
(if included in the transmitter model). The display always shows the
currently measured readings if the measurement is operating with
out
error. For more information on transmitter errors, see section
Error
Messages on the Display
on page 41.

CHAPTER 3
INSTALLATION
This chapter provides you with information that is intended to help you
install HMDW80 series transmitters.
Selecting Location
When mounting duct model transmitters:
- Avoid installing in a location where condensation may fall on the
sensor inside the duct.
- Position the sensor in the center of the duct.
- Select a site where the transmitter can be installed horizontally, onto
the side of the duct.
When mounting wall model transmitters:
- Select a location that represents well the area of interest.
- Do not install on the ceiling.
- Avoid placing the transmitter near heat and moisture sources, close to
the discharge of the supply air ducts, and in direct sunlight.
When mounting outdoor transmitters:
- Install in a place that receives minimal direct sunlight. In the northern
hemisphere, the North side of the building typically provides a
suitable shaded location.
- Avoid placing the transmitter near windows, air conditioning units, or
other heat and moisture sources such as cooling towers.
- Install the transmitter at least 2.5 m above ground level.
