Condensing units
6.11
There are numerous manufacturers of external cooling devices on the market that can be
used with air conditioning units. Almost every manufacturer of a cooling or condensing unit has its
own control method. This causes a great deal of fragmentation in the way refrigeration or
condensing units are controlled, and sometimes it is very difficult to reconcile the control of an air
conditioning and condensing unit. Therefore, it is possible to choose the type of control of the
condensing unit (chiller) according to the specific control methods of each manufacturer, which is
continuously updated. The condensing unit control is prepared to control 6 separate units.
In the event of a failure or defrost of the condensing unit, the fan speed can be reduced to
reduce the supply air temperature to achieve the required supply air temperature. The
compensation for these conditions must be set in the menu
