Design
VAV controller casing is made from galvanized sheet steel. The damper blades are from extruded aluminium profile.
The insulated version (OPTIMA-SI) has the casing wrapped in closed cell insulating foam mat, 19 mm thick. The
insulation is protected by galvanized steel sheet. Special design of multi-point averaging cross flow sensor from
aluminium assures an accurate air flow readings. The measurement impulse tubes from polyurethane connect the
measurement probe with the measurement sensor. The compact control/actuator unit consists of: measurement
sensor, transmitter, controller and the damper actuator.

Controls
The VAV controllers are equipped by OEM compact control/actuator units from Siemens. Versions without any BUS
compact control/actuator units are factory calibrated as standard to the air volume control range V
min
... V
max
. The
dimension table shows this standard setting. Upon request the control range V
min
... V
max
can be adjusted to
customized settings prior to dispatch. The air volumes can also be re-adjusted on site with AST-20 hand held service
tool. If specific air values for V
min
and V
max
would be required, this must be indicated prior to order of the units for
adequate calibration in the factory.
