• Offset Position is: 40000 + N*32 + Address as shown in table, where N is Water Chiller Address.
• Status (real value) and Set (value ordered) parameters have usually the same value but, in some cases, some of them can be
different. It is recommended to use Set parameters for normal control.
• (*) When Temperature Setting and Operation Mode are changed at the same time, order first the operation mode change and later
set the desired temperature.
• (1) The availability of these new parameters also requires the new chiller software C-387, which available from June 2013. For
units manufactured before this date adress to your technical service.
