    Fig. 4: Info bar in Unisab III display 1.1.3 Front panel The Unisab III front panel is divided into three sections: The control section - to control the compressor. The menu section - to select menu pictures and change values.
  • Page 10 The Enter (check) key has several functions. When changing the set values, pressing this key will enter the change into the Unisab III memory. To make changes, you must use the pass- word provided by Johnson Controls Denmark. As to the encoding of a password, see section 1.1.6.

  • Page 11: Menu Structure

    The function of each key will always be shown in the display above the key. 1.1.4 Menu structure Unisab III includes a number of different pictures for compressor operation, set values, con- figuration, etc. These pictures are built up in a menu system where a certain picture can be selected by means of the arrow keys.
