The controller ensures optimum filling of the evaporator under all load conditions,

resulting in low energy consumption. Various monitoring functions enhance operat-

ing safety and extend the plant’s life.

The controller has been designed for use with all standard types of dry expansion

evaporators such as plate, tube and fin heat exchangers and is therefore especially

suited for integration in chillers, air handling units, etc.

Auxiliary functions enhance efficiency and supervision of the refrigeration plant:

• Enabling operation via a digital input, e.g. by any operational status signal from

the compressor

• Selection of different types of refrigerants

• Conversion of pressure to the respective temperature of the selected refrigerant

• Display of all measuring variables and of the valve's manipulated variable

• Integrated cooling capacity control

• Two superheat circuits

• Sensor monitoring

• Compressor safety controls
