– 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.
