2-10V Duct Humidity Sensor Installation Instructions
This document covers the operation and installation instructions for the following Condair duct humidity sensor:
Kit No. Component No. Description
2597926 1509857 2-10V Duct Humidity Sensor
The humidistat can be congured 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 humidication 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 x the housing to the duct using the 4 self-tapping screws provided.
6. Close the cover and x 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.
