Overview
The 210-2002 is a Vaporstat™ wall-mounted
dewpoint sensor. The sensor is designed for
measuring indoor or outside dewpoint or absolute
humidity level.
Sensor Wiring
1. For wiring the dewpoint sensor to a CPC
input board, use Belden #8761 shielded two-
conductor cable or equivalent.
2. Connect the BLACK and WHITE wires to the
screw terminals on the sensor’s connector as
shown in
Figure 1
(connect BLACK to Signal
Ground and WHITE to 0-5V Output). Clip the
SHIELD wire.
3. Connect the SHIELD and BLACK wires to the
0V terminal of the input board. Connect the
WHITE wire to the SIG terminal of the input
board.
4. Connect 24VAC (a separate 120VAC/24VAC
transformer must be used P/N 640-0039) to
the power terminal on the dewpoint sensor
back plate using the BLACK and WHITE wires.
(This 24VAC transformer must only be used
to power this dewpoint sensor. Do not use
this transformer to power additional
devices.)
5. Locate the input dip switch for the sensor
point, and set to the OFF position (LEFT for
MultiFlex, DOWN for 16AI). Refer to the input
board’s user manual for locations of the
input dip switches.
Controller Setup
NOTE:
DO NOT set this sensor up with a sensor type
of “Dewpoint”; that setting is only for CPC
Dewpoint Probes (P/N 203-1902). This
dewpoint sensor MUST be set up as a linear
sensor type.
E2/Einstein
1. After logging into the controller, press
6+ to open the Input Status screen or
press the Ikey, (System
Configuration), (Input Summary). (If
using an Einstein, press
F8
(ACTIONS) from
the Home screen. Press
Y
(System Setup).
Press
6
(Input and Output Point Setup).
Press
1
(Input Summary) to open the Input
Summary screen.)

2. Highlight the input-point the sensor is
attached to and press (SETUP) to set
up the input, or press to open the
Actions Menu and select 5(Setup). (If using
an Einstein, select an input point and press F7
(SETUP IN) to open the Analog Input screen.)
3. Select Analog to set up the input as analog.
The Analog Input screen will display:
4. Once on the Analog Input screen, move the
cursor to the Sensor Type field, press
(LOOK UP), and set to Linear. (If using
an Einstein, press F7 (LOOK UP) and set to
Linear.)
5. Move cursor to Select Eng. Units and press
(LOOK UP). Set this field to DF (for
Degrees Fahrenheit). (If using an Einstein,
press F7 (LOOK UP) and set to DF.)
6. Then set the following sensor properties:
•Set the Modify field to: EndPoint. (If
using an Einstein, press F7 (LOOK UP)
and set to EndPoint.)

•Set the Low End Point field to 0.
•Set the HighEnd Point field to 5.0.
•Set the Low Eng. Units field to 0.
•Set the High Eng. Units field to 80.
•Set the Low End Limit field to -0.5.
•Set the HighEnd Limit field to 6.5.
REFLECS
1. Log in to the controller.
2. From the Main Menu, select 4-Sensor
Control.
3. From the Sensor Control screen, select 2-
Setup.
4. From the Select Sensor screen, choose the
sensor you wish to set up:
5. Once you select a sensor, the Sensor Setup
screen opens. Enter a name for the sensor in
the Name field (for example, DEWPOINT)
and set the Type field to Linear by using the
scroll keys or pressing the red button + the
(L) button.
6. Press 0to go back to the Sensor Control
screen. Select 3-Setpoints and then choose
the sensor to set Gain and Offset.

7. Set Gain to 16, Offset to 0(the default) and
enter degrees fahrenheit units into the Eng.
Unit field (for example, type DEGF).
8. To check the sensor input value, press 0to
go back to the Sensor Control screen and
select 1-Status.
Set Up Zero Calibration
The Zero Calibration mode allows the user to
calibrate the sensor to a verified zero concentration
of water vapor. For best results, allow the sensor to
warm up for at least 10 minutes.
For zero calibration, all tubing should be connected
between the gas bottle and the sensor inlet flow port.
Before initiating calibration using the sensor keypad,
the gas should be flowed to the sensor at a rate of 80-
100 cc\minute for a period of five minutes.
Observe the following steps to set up Zero Calibration
mode.
1. Attach the short hose to the bottom port on
the flowmeter.
2. Attach the long hose to the top port on the
flowmeter.
3. To ensure the meter is kept in the vertical
position, secure the flowmeter to the side of
the gas bottle using the supplied tie wrap.
4. Remove the protective cap from the
nitrogen bottle and attach the gas regulator.
5. Attach the open end of the bottom hose
(located on the flowmeter) to the gas
regulator. Slide the hose far enough on the
gas port to ensure a secure, airtight
connection.
6. Insert the male luer fitting (located on the
longer hose) into the calibration port,
located on the bottom of the dewpoint
sensor.
7. Verify that all components are installed
correctly and initiate the calibration process
by turning the knob on the regulator. Turn
the knob until the indicator reaches 7 psi.
8. Turn the flowmeter knob until the floater
reaches 80-100 cc/minute.
9. Allow the gas to flow for at least 5 minutes
before proceeding.

10. Press the Clear and Enter buttons together
and hold for five seconds. The word CAL will
appear in the topline of the LCD display:
11. Use the arrow buttons to toggle to the Zero
Calibration mode.
NOTE: Prior to pressing the Enter button, the zero
gas should be flowing to the dewpoint sensor
for atleast five minutes.
12. When ZERO is displayed, press the Enter
button to initiate the calibration process.
13. Once the Enter button is pressed, the
calibration process will take five to seven
minutes during which time the green LED
below the display will flash. Once calibration
is completed, the sensor will revert to its
normal display mode.
Calibration Layout
Refer to the calibration topic of the manufacturer’s
manual for the sensor’s zero calibration layout.
Contact your CPC sales representative for calibration
kit (P/N 210-2005) purchasing information.
