4 / 20 | Variable Air Volume Controllers
Design
OPTIMA-S controllers are constructed from galvanized
sheet steel casing and aluminium prole blades.
The casing contains a robust anged mounting frame to
assure the sturdiness of the controller and to facilitate
the mounting to ducts. The aerofoil blades are opposed
action and are made from extruded aluminium.
The blades are equipped by rubber gaskets eliminating
leakage in closed position. The blade axes are sitting
in self lubricating polymer bearings. The blades are linked
by a cog/rod positioning mechanism. The measurement
probe from alunimium is connected to the VAV controller
by exible polyurethane impulse tubing.
Available sizes (mm): 200 × 100 to 1200 × 1000
with steps of 50 mm in height and width.
The insulated version OPTIMA-SI has 19 mm thick
polymer foam insulation around the casing,
covered by galvanized steel protection sheet.
Controls
The VAV controllers are as standard equipped
by compact controllers/actuators with analog setpoint
and feedback signals in mode DC 2 V ... 10 V
or DC 0 V ... 10 V. The compact controllers are equally
available with MP-BUS, MODBUS, BACnet, KNX 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 (only possible with MP-BUS communication
on board).
VAV compact controllers are factory calibrated
as standard to the air volume indicated in the Tab. 4
or upon request can be adjusted to site required settings
prior to dispatch on V
min
and V
max
range. The air volumes
can also be readjusted on site with ZTH-EU hand held
service tool or, for the type OPTIMA-S...GO... by dials
on the controller. If specic air volumes 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.
