•
As a supply air temperature controller:
−
In the supply air duct downstream from the supply air
fan if fan is installed after the last air handling unit,
otherwise
−
In the supply air duct downstream from the last air
handling unit in a distance of 0.5 m
•
As a minimum supply air temperature limiter:
In the supply air duct as close as possible to the air dis-
charge into the room
•
As a dewpoint controller:
Immediately downstream from the droplet separator of
the air washer
Mounting
Procedure:
1. First mount the flange. For drilling holes, refer to “Di-
mensions”.
2. Bend flexible sensing element manually (never use a
tool) so that – when mounted – it stretches diagonally
across the air duct .
Note! The flexible sensing element may not touch the
duct wall: The minimum clearance is 50 mm and the
smallest permissible bending radius 10 mm

3. Fit mounting flange.
4. Slide controller on mounting flange and snap it on.
Electrical installation
•
Ensure that the local regulations for electrical installa-
tions are complied with
•
The connecting terminals are located under the flexible
plastic cover
•
Make wiring according to the plant documentation. If not
available, use the connection diagrams contained in
these Installation Instructions
•
Observe the permissible cable lengths
•
Switch on power only when commissioning the controller

Indication of operating state
The red LED indicates the controller’s operating state:
•
LED lit: Mains voltage present
•
LED flashes: In test mode
The LED is also visible when the cover is fitted.
Commissioning
When used as a controller
1. Remove housing cover.
2. Lift flexible plastic cover so that you can access the
setting elements.
3. Make the settings:
−
Operating action (DIP switches 1 and 2)
−
Control mode and (with PI mode) integral action
time (DIP switches 3 and 4)
