6Condair UDC
1 Condair UDC
1.1 Functional description
The universal controller Condair UDC is a programmable controller and sensor for duct installation. It
has 2 control loops with 2 PI sequences each. The Condair UDC has an RS485 communication interface
which enables programming with a PC and the Easyset program. The Condair UDC uses the universal
X2 operating system.
Note: Ex factory the Condair UDC is congured as a humidity and temperature sensor.
1.2 Safety
Please observe all local regulations concerning electrical installations.
The installation work must be performed only by adequately qualied personnel (electrician or work-
man with equivalent training).
Warning - danger of electric shock! Before starting the installation work the unit to which the Condair
UDC will be connected must be disconnected from the mains and may be reconnected to mains only
after all installation work has been completed.
Warning! The electronic components inside the Condair UDC and the humidier are very susceptible
to electrostatic discharges. For the protection of these components, measures must be taken during all
installation work to prevent damage caused by electrostatic discharge (ESD–protection).
1.3 Delivery
The delivery includes:
– Universal duct controller Condair UDC
– Cable gland
– Fixing material
– Duct ange
– Installation manual

7Condair UDC
1.4 Mounting location
The Condair UDC is installed directly on the duct.
– Mounting in the extract air duct (recommended):
Mount the UDC in the extract air duct close to the air outlet of the room but downstream from a
extract air fan if one is present.
– Mounting in the supply air duct:
Mount the UDC 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 distributor (see manual
of the humidier).
1.5 Installation
1. At the place of location drill a hole with a diameter of 16 mm (5/8") into the duct (see dimensional
drawing).
2. Stick the supplied self-adhesive gasket concentrically over the hole in the duct and attach the duct
ange to the ventilation duct using the self-tapping screws supplied.
3. Insert the probe of the universal controller through the duct ange into the duct and secure it with
the lock nut.
4. Loosen the screw on the housing cover and open the cover.
5. Lead connecting cable through the cable gland into the controller and connect wires to the terminals
according to the wiring diagram.
6. Close cover and x it with the screw (do not tighten screw too much).
