6.4.4 Plant
The Plant menu includes set-up for the refrigeration plant. Some points are used for sequenc-
ing. COP and chiller set-up is also carried out here.
1: Refrigerant
Not defined
R717
R22
R502
R23
R404A
R134A
R507
R410A
R407C
R744
R1270
R290
R000
For R717 (and all other refrigerants) the converted pressure is always shown as dew point
values. Before the user-defined refrigerant R000 is chosen, the refrigerant curve must be en-
tered in picture Setup/Configuration/R000. See also subsection 3.5.13. Refrigerant R000.
2: Compr.
This number must be entered into Unisab III. The compressor has then been "named". Two
compressors must never have the same Compr. number.
3: Start
This number must be entered into Unisab III. This is this compressor's start number in the
Multisab sequencing system. Two compressors must not have the same start number on the
same Multisab System.
4: System
This number must be entered into Unisab III. This is this compressor's system number in the
Multisab sequencing system. It indicates which Multisab sequencing system this particular
compressor is assigned to. Two or more compressors may have the same system number.
