The Local and System Data display messages for the
YCAS 3-System models follow the same format as the
YCAS 2-System Model messages as given in the pre-
ceding paragraphs. The only difference is that after the
System 2 data is completed, pressing the key displays
System 3 data before looping back to the Load/Unload
Timer Display.
YCAS 4-System Models:
YCAS 4-System models are constructed in two sec-
tions. One section contains number 1 and 2 refrigerant
systems plus their associated evaporator. The second
section contains the number 3 and 4 refrigerant sys-
tems plus their associated evaporator. Both sections have
their own control panel, but only the System 1 and 2
panel is fitted with a keypad and display.
The Local and System Data display messages for the
YCAS 4-System models follow the same format as the
YCAS 2-system model messages as given in the pre-
ceding paragraphs. The only difference is that after the
System 2 Data is completed, pressing the

4.4 OPERATING DATA - REMOTE PRINTOUT
The follow text shows a typical example printout ob-
tained by pressing the Operating Data key with an op-
tional printer attached. In this case an example is shown
for a YCAS 2-system Chiller. YCAS 3-system models
and YCAS 4-system models provide similar printouts
for the appropriate number of systems:
The System Cooler Inlet Refrigerant
Temperature will be printed if the unit
is in R-407C mode.
