CDC-NA 2-10V Duct Humidity Sensor

Product Information: CDC-NA – 2-10V Duct Humidity Sensor

The CDC-NA – 2-10V Duct Humidity Sensor is a Condair duct
humidity sensor that can be configured for either humidity control
or as a high limit safety device. The kit includes Component No.
2597926 and Description No. 1509857, which is the 2-10V Duct
Humidity Sensor.

Product Usage Instructions:

Refer to installation overview in section 2 of the user
manual.
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.
Loosen the screw on the housing cover and open cover.
Lead connecting cable through the cable gland and connect wires
to the terminate according to the wiring diagram.
Stick 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 4 self-tapping screws provided.
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.

2-10V Duct Humidity Sensor

The humidistat can be configured for either humidity control or as a high limit safety device.

1 Mounting and Installation
Location: The Condair CDC-NA is installed directly on the duct. Mounting in the extract air duct (recommended):
Mount the CDC-NA in the extract air duct close to the air outlet of the room but downstream from an extract air fan if one is present. Mounting in the supply air duct: Mount the CDC-NA in the supply air duct at least 3 meters downstream from the nearest fan and coil and with a minimum distance of 5x the humidification distance to the steam distribution.
Installation:
Refer to installation overview in section 2. 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.
