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 terminal 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.

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.
- 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 <100 ft distance from the unit.
