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○consideration.

Control•○ 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.

Figure 6. Individual room control with overflow air. Extract air is slave controlled by the total supply air volume.

Control – ExampleBelow,○a○couple○of○examples○are○shown○of○how○REACT○can○work○in○a○demand-controlled○ventilation○system.○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○completely.

Slave control - ExampleA○REACT○unit○can○be○slave○controlled○from○another○REACT○or○from○REACT○CU.○Slave○control○can○also○be○achieved○by○○parallel○connection,○i.e.○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.○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○applicable.
