DCC-NA 0-10V Digital Duct Humidistat Package
Product Information: DCC-NA – 0-10V Digital Duct Humidistat
Package
The DCC-NA – 0-10V Digital Duct Humidistat Package is a Condair
digital humidistat package that is used to control the humidity
levels in ducts. The package includes a 2-10V duct sensor and a
wall humidistat without a sensor. The product is designed to be
mounted downstream of the steam distribution at a distance of 1.5
times the absorption distance, which is typically 10-12 feet or
3-3.7 meters.
The product is equipped with user and control parameters that
can be accessed by entering the correct password. The user
parameters include UP 00, UP 01, UP 02, UP 03, and UP 04, which
allow users to enable change of operation modes, change of
setpoints, state after power failure, Celsius or Fahrenheit
selection, and type of content for large digits. The control
parameters include CP 00, CP 01, CP 02, and CP 03, which allow
experts to change the minimum setpoint limit in humidification
mode, maximum setpoint limit in humidification mode, and start
delay for fans.
Product Usage Instructions
Follow the below instructions to install the DCC-NA – 0-10V
Digital Duct Humidistat Package:
- Choose a location for installation downstream of the steam
distribution at a distance of 1.5 times the absorption distance
(typically 10-12 feet or 3-3.7 meters). - Drill a hole with a diameter of 16 mm (5/8 inch) at the chosen
location and four holes for the self-tapping screws into the
duct. - Loosen the screw on the housing cover and open the cover.
- Lead the connecting cable through the cable gland and connect
wires to the terminate according to the wiring diagram. - Stick the gasket on the sensor side centrally on the housing
(self-adhesive). - Insert the probe into the hole in the duct, then fix the
housing to the duct using the four self-tapping screws
provided. - Close the cover and fix it with the screw (do not tighten the
screw too much).
Follow the below instructions to access the user and control
parameters:
- Press and hold both the < and > buttons simultaneously
for three seconds. The display will show firmware version and
revision number. - Press the < button to start login. The small digits show
CODE. - Select the correct code (password) using the < and >
buttons. The code to access user parameters is 0009. The access
codes are fixed and cannot be changed. - Press the < button after selecting the correct code.
- Once logged in with 0009, the user/display parameters are
displayed immediately. - Select the parameters with the < or > button. Change a
parameter by pressing the < button. The symbol is displayed to
indicate that the parameter may be modified. Use the < or >
button to adjust the value. - After you are done, press the < button to save the new value
and return to the selection level (symbol disappears after
selection is saved). Pressing the > button without pressing the
< button will discard the value and return without saving. - Press the > button to leave the menu. The unit will return
to normal operation if no button is pressed for more than 5
minutes.

* Component No. 2520266 consist of two parts.
1 Mounting and Installation
1509857 Duct Sensor Installation
Location
Refer to installation overviews in section 2.
The duct sensor should be installed directly on the duct in an area where the air is well mixed with uniform flow. · Used as supply air humidity sensor: If the sensor is used as a supply air humidity sensor it should be
mounted downstream of the steam distribution at a distance 1.5 times the absorption distance (typically 10-12 ft or 3-3.7m).
· Used as return air humidity sensor: If the sensor is used as a return air humidity sensor it should be mounted close to the air inlet but downstream from a return fan if one is present.
Installation 1. At the place of location drill a hole with a diameter of 16 mm (5/8″) as well as 4 holes for the self-tapping
screws into the duct. 2. Loosen the screw on the housing cover and open cover. 3. Lead connecting cable through the cable gland and connect wires to the terminate according to the wiring
diagram. 4. Stick gasket on the sensor side centrally on the housing (self-adhesive). 5. Insert the probe into the hole in the duct, then fix the housing to the duct using the 4 self-tapping screws
provided. 6. Close the cover and fix it with the screw (do not tighten the screw too much). Note: We recommend using 18-gauge wire, and maximum <100 ft distance from the unit.
2520261 Humidistat w/o Sensor Installation
Location
Install the digital wall humidity controller in a protected and easily accessible place at last 1.5 m above the floor to the wall (mounting on flush-mounting or surface-mounting box).
Installation
Refer to installation overviews in section 2.
1. Open the screw of the housing and remove mounting plate with the connecting unit.
2. Connect wires of the connection cable to the terminals according to the wiring diagram. 3. At the place of location fix mounting plate (plastic screw facing downwards) with two screws to the
flush-mounting or wall-mounting box (see dimensional drawing). 4. Carefully snap housing onto the mounting plate and fix it with the screw (do not tighten screw too much). Note: We recommend using 18-gauge wire, and maximum <100 ft distance from the unit.
