Installation
Installation orientation
Any installation orientation.
When installing in horizontal ducting, the operating
side (rotary knob) must be arranged laterally (right/
left) or below.
Observe airflow direction!
Upstream conditions
The volume flow rate accuracy of CAV controllers
applies to a straight upstream section of the duct.
Bends, junctions or a narrowing or widening of the
duct cause turbulence that may affect volume flow
rate measurement. Depending on the respective
installation situation, information on the straight duct
section upstream of the control unit must be
observed.
Duct connections, e.g. branches off the main duct,
must comply with EN 1505.

Attaching sealing tape
To achieve the tightness class of the ducting,
sealing tapes have to be installed between the
ducting and the controller at both sides of the
flange, e.g. self-adhesive sealing tape.
Ensure that the sealing tape (Fig. 6/1) is attached
flush with the flange.
