1 Features
Air handlin Air Handlin Control box Heat pump • Wide range of Daikin units offers maximum application potential plus flexible control options.
• The system provides optimized air conditions such as fresh air and humidity control etc. and can be used in small warehouses, showrooms and offices.
• Control box and expansion valve kit are required for each combination plus an air handling unit.
• Both option kits are designed for indoor and outdoor installation and can be wall mounted.
• High flexibility in control possibilities thanks to a wide offer of controls: control x: room, suction or discharge temperature can be controlled via DDC control (field supplied); control y: control by fixed evaporating temperature; control z: room or suction temperature control via Daikin remote controller. Remote ON/OFF can be achieved by an optional adapter KRP4A51.
