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).

6 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.

Measurement rods are of extruded RTC Room thermostat for temperature control of a room, (connects to the REACT regulator). DETECT Quality Carbon dioxide sensor with integrated tempera-ture sensor, for either room or duct installation.

9 20180705 PlanningGeneral Designed for demand-controlled ventilation in rooms with variable loads. Intended for comfort ventilation. 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.

10 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. 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.
