A new approach to system linearization and decoupling is presented for climate control of greenhouses and more specifically for the operation of heating, cooling and moisturizing. High level programming, which provides an easy way to building models, is a feature of most research but also field control systems. The method is applicable to any air conditioning system and is expected to gain wide acceptance in modern SCADA systems with extended computational capabilities.
