REACT and REACT MB with compact controller. REACT GUAC with spring return actuator and separate controller. The controller has a display enabling direct reading. Easy commissioning and handling without the need for a sepa-rate hand unit. All you need is screw driver. Available in the following designs: Circular version Rectangular version With Modbus With spring return actuatorFeatures Intended for heated spaces (0 - 50 C).

4 Storage and transportation, -20 - 50 C Ductwork Leakage Classes in accordance with SS-EN 1751 Leakage class C to the surroundings. Circular version: class 4, closed damper Rectangular version: class 3, closed damper Air flow is measured over one or more measuring rods. All settings are displayd in actual values. Changes of min. and max flows are made directly in the control-ler through potentiometers. Distance inbetween the motor shelf and the damper (30 mm) is dimensioned for easy condensation isolation in duct systems. Running time open/close (90 degrees): 5 Nm - 100 s 10 Nm - 150 s 15 Nm - 150 s Spring return actuator, running time electricity: 5 Nm - 100 s 10 Nm - 150 s Running time spring max 20 s (90 degrees)Materials and surface treatment All sheet metal parts are made of galvanised sheet steel. Measurement rods are of extruded RTC Room thermostat for temperature control of a room, (connects to the REACT regulator).

Intended for comfort ventilation.

6 Humid, cold or aggressive environments should be avoided. Environmental and/or air temperatures should be within 0 - 50 C. Can be installed in both supply and extraxt air systems. Pressure-independent but requires a minimum air flow equivalent to the open damper pressure drop to fun-ction properly. Factory calibrated with a nominal air flow (Qnom) When carrying out design work, the minimum air flow required by REACT has to be taken in to Controlled by heat, carbon dioxide or occupancy. The factory setting is always 0-100% = 0 l/s Qnom. Can be forced controlled to: maximum and minimum air flow. fully open or fully closed damper When used for slave control, slave and master units must be of the same dimension. Can be used as a constant flow damper. (Qmax= 0 and Qmin = desired constant flow) Delivered with 0 - 10V set value and actual value signal.

7 Adjustable to 2 - 10V set value and actual value signal. REACT can be analogically connected to Building Management Systems (BMS) Possible to obtain with Modbus control Possibility to obtain REACT with spring return dataNOTE: To obtain the correct functionality of the control and regulating equipment it is of great importance that all interconnected regulating equipment has the same voltage24 VDC/24 VAC , 50-60 HzPower consumption, for transformer rating: REACT 5 W4 VAREACT 10 Nm2,5 W4,5 VAREACT 15 Nm3 W4,5 VAGUAC DM3 controller0,6 W1,3 VASpring return actuator 5 Nm6,5 W (standby 2 W)7, 5 VASpring return actuator 10 Nm5 W (standby 2 W)8 VAFigure 5. Air flow control with temperature sensor or CO2 sensor (supply and extract air controlled in parallell by the temperature sensor).Figure 6. Individual room control with overflow air. Extract air is slave controlled by the total supply air ExampleBelow, a couple of examples are shown of how REACT can work in a demand-controlled ventilation system.

8 When regulation via a CO2 sensor is chosen, the room thermostat is excluded as DETECT Q has an integrated temperature sensor that combines its output with the value from the CO2 sensor. The greatest signal from DETECT Q is sent to REACT to regulate the air flow. With the help of the presence detector DETECT O, the 0-10 V signal can be susopended so that the REACT unit regulates down to a minimum air flow when a room is unoccupied. DETECT O can also be connected so that REACT shuts down control - ExampleA REACT unit can be slave controlled from another REACT or from REACT CU. Slave control can also be achieved by parallel connection, by connecting the room thermostat signal to both the extract and supply air units. Parallel connection is recommended because the control signals are sent to both units at the same time and air flow can be freely set within the working range of REACT .

9 Slave control is limited as the slave unit cannot have a greater air flow than the master unit and because lower flows can only be obtained as a percentage of the master unit air flow. In systems with REACT CU as sensor unit, the slave control principle is always CUREACTREACTRRKMBFKMBFBFBFMKKL egend to figures 5-6:R = RTC or DETECT Q M = DamperK = Controller BF = Flow sensor520180705 Swegon reserves the right to alter speci measurements circular versionSizeA (mm)Inst. measurements (A + 10 mm)1004724821254724821604724822004724822 50522532315552562400695705500*822842630* 120 01220*Size 500, 630 has installation dimension A+20 8.
