APPLICATION EXAMPLES10Specifications are subject to change without notice. When ordering, use the latest data sheets available at M-System web site.Office BuildingsAir Conditioning Control for Large OfficesIn large buildings, heat source equipment such as boilers and freezers are commonly installed in machine rooms to provide overall air-conditioning.Each story has an air handling unit (AHU) that distributes cooled (or heated) air to the floor. The air flow from the AHU is increased or reduced at a damper motor that is controlled by a variable air volume (VAV) controller. It receives the readout on the wind sensor and the temperature setting on the remote controller, and adjusts the aperture of the damper to keep room temperature as close to the preset one as possible.Air Conditioning Control for Small Rooms and Window PerimeterIn small office rooms or places where temperature conditions vary due to exposure to sunlight, fan coil units (FCU) are in common use. Heat source (hot and/or cold water) is supplied per unit to control temperatures of individual rooms. The FCU controller provides control of hot and/or cold water valves and a fan of the FCU in the room so that the room temperature is stabilized at as close to the preset one as possible.BA Controller• HVAC Control for Large Offices• HVAC Control System for Cubicles and Window AreasRemote I/O• Signal Transmission that Requires High Reliabilityto Upper StagesExhaustOutside(Primary)(Secondary)Hot or Cold WaterHeat Source EquipmentHeat Source EquipmentHeat Source EquipmentFilterCooling and Heating CoilFanLarge OfficeVAV Remote ControllerVAV Remote ControllerVAVVAVLONWORKSSupplySupplyReturn AirReturn Return Heat ExchangerFanDDCVAV ControllerVAV ControllerWind Speed SensorDamper MotorRoom Temperature(via VAV remote controller)AHU (Air Handling Unit)CompartmentLONWORKSFCURemote ControllerFCU controllerHot or Cold WaterHot or Cold Waterto other FCUto other FCUTemperature SensorFCUFCURemote ControllerFANCoil(Heat Exchanger)MM(Primary)(Secondary)SupplyReturnFCUControllerBA9-FCUVAV ControllerBA9-VAVMulti-channel, Mixed Signal Remote I/OR3 SeriesFacilities, BuildingsAir-Conditioning, Hot Water SupplyCold WaterHot Water, SteamDistrict Heating and Cooling PlantLarge CapacityHeat PumpLarge CapacityHeat PumpLarge CapacityHeat PumpApplications introduced in this page are only available in Japanese market or for limited example outside Japan.
