OPTIMA-S-FCS_BM Variable Air Volume Controllers

DescriptionOPTIMA-S-FCS...BM is a variable air volume (VAV) controller with or without insulation. The product is intended to control the flow volume of supply or return air. The product is installed into rectangular ducts. The product is ideal for all applications, where a variable air flow volume in ventilation, cooling or heating is required and in spaces with increased dust polution (industrial and manufacturing sites, workshops, public halls, etc.)Highlights• Damper tightness class 4 according to EN 1751• Casing tightness class C according to EN 1751• High measurement/control accuracy of 5 %• Air volume range of 144 m3/h to 47500 m3/h• Operating range of pressure drop up to 1000 Pa• Actuators with quick transition or safety positioning function available• OPTIMA-SI-FCS...BM version with external insulation for radiated sound reductionTypes of Product• OPTIMA-S-FCS...BM: Non-insulated VAV controller• OPTIMA-SI-FCS...BM: Insulated VAV controllerType of Controller• BM: Modbus-RTU or BACnet MS/TP switchable port for communication of all variables, analog setpoint and feedback signals DC 0 (2)V … 10 V applicableTypes of Actuators• S: Standard actuator• Q: Actuator with short transition time• QE: Actuator with short transition time and electric safety function• F: Actuator with mechanical safety function – spring returnList of Accessories• LDR-A: Sound Attenuator• ZTH-EU: Handheld Tool• ZIP-BT-NFC: Communication Port Bluetooth/NFCDesignOPTIMA-S-FCS...BM consists of a casing, aluminium profile blades with rubber gaskets and a modular VAV control device.The casing is manufactured from galvanized sheet steel. The casing contains a robust flanged mounting frame for installation into ducts.The frame assures the sturdiness of the controller and facilitates the mounting to ducts.The blades are manufactured from extruded aluminium. The blades are opposed action. The blades are equipped with rubber gaskets. The gaskets eliminate leakage in the closed position.The blade axes are in self-lubricating polymer bearings. The blades are linked by a cog/rod positioning mechanism.The modular VAV control device consists of an aluminium measurement probe, polyurethane measurement impulse tubes, an airflow transmitter with a static sensor, a modular control unit and an actuator.The aluminium measurement probe is connected to the VAV controller with flexible polyurethane impulse tubing. The special design of the multi-point averaging cross-flow sensor assures accurate air flow readings.The measurement impulse tubes connect the measurement probe with the airflow transmitter.There is no air flow through the impulse tubing.OPTIMA-SI-FCS...BM has 19 mm thick polymer foam insulation around the casing. The insulation is covered by a galvanized steel protection sheet.
