Design
VAV unit housing constructed of galvanized steel sheet,
large surface pleated for extra stiffness. Internal thermal
acoustic insulation of bre glass material, dual density
insulation cover tissue is used to protect the berglass
insulation to protect the deterioration of the insulation
for air speeds of 20-25m/s.
Acoustic insulation in the housing has aerodynamic
ow for extra low sound level. For even more noise
attenuation in the version OPTIMA-RS-I... the double skin
inlet with isolation is foreseen. Double skin low leakage
damper with airtight neoprene gasket seal.
Special design of centre averaging multi-point airow
differential cross velocity pressure sensor assures an
accurate air ow readings even in difcult installations.
Button punch snap lock seams, lock form with airtight
nylon bearings to assure low casing leakage.
Rectangular outlet with M8 riveted nuts, suited for
connecting to duct ange. 12 mm aluminium shaft with
nylon bearings
Available sizes:
Inlet: from ø 100 to ø 400 mm

Controls
The VAV terminal units are as standard equipped with
BLC (Belimo compact) controllers (LMV-D3 or NMV-D3)
without any MP or LON communication capability to
be used as stand alone or in master and slave setting.
The compact controllers are equally available with
MPBus, ModBus and LON communication capability. On
demand as alternative, Gateway communication units
can be provided and can be connected later in time to
building management systems to create a zone control
by creating bus-rings solutions (only possible if MP-Bus
communication is installed).
VAV and Compact controllers are factory calibrated as
standard to the air volume indicated in the table or upon
request can be adjusted to site required settings prior
to dispatch on Vmin and Vmax range. The air volumes
can also be readjusted on site with ZTH-Gen hand held
service tool or, for the type Optima-S-...GO... by dials on
the controller. If specic air volumes for Vmin and Vmax
would be required, this must be indicated prior to order
of the units for adequate calibration in the factory.
