Design
OPTIMA-S-FC...BM consists of a galvanized steel sheet casing, aluminium profile blades with rubber gaskets and a
modular VAV control device. OPTIMA-SI-FC...BM is equipped by an insulation for sound reduction. The insulation is a 19
mm thick closed cell foam mat, protected by galvanized steel sheet. The casing contains a robust flanged mounting
frame for installation into ducts. The blades are opposed action. The modular VAV control device consists of an
aluminium measurement probe, polyurethane measurement impulse tubes, an air flow transmitter, a modular control
unit and an actuator. The measurement probe is a special design cross. It is a multi-point averaging flow sensor for
accurate air flow readings. The measurement impulse tubes connect the measurement probe with the air flow
transmitter.
Actuators
• S: Standard actuator
• Q: Actuator with short transition time
• QE: Actuator with short transition time and electric safety function
The default manufacturer setting of the actuator safety function is closing after power supply interruption.
Upon request the manufacturer setting can be changed to opening after power supply interruption. Adjustment of
intermediate final safety position (0% … 100% opening) is possible.
The possibility to change the safety function on site is available.
