NOTUS-R
Constant air ow controller for circular duct installation
Ordering code
Example of the ordering code:
NOTUS-RI - 125 - M0
CAV controller NOTUS with isolated body, nominal size (connection
diameter) 125 mm, manual adjustment of ow volume.
Description
NOTUS-R is a constant air volume ow controller with
mechanical type of operation (no need for auxiliary
energy or actuation). It is intended to control the
constant air ow independently of the duct air pressure
in the range of 50 Pa to 1000 Pa. The constant air
ow value can be set by a rotating dial within a range
dependent on the size of product manually (type M0) or
by an electric actuator (type M1). The actuator position
can be controlled continuously by DC 0 V... 10 V signal.
The control setpoint can be chosen by actuator also from
two discrete positions adjusted by mechanical stops on
actuator (Types M1 and M2).
The ow volume setup positions with corresponding
control voltage values can be found on the product
label. More information to adjustment of types
M0, M1, M2 can be found in installation manual
“InstalMaintenOperInstr_PP-66_NOTUS-R”.
The ratio between minimal and maximal air ow setup
value is app. 1:3.
The control error is ± 10 % of the set-point value on the
whole control range. The uncertainty of the setup dial
scale is ± 4 %
With standard-sized circular connections it ts into the
circular ducts of 80 mm up to 400 mm in diameter.
