16: Flow evap.
No
Yes
Select Yes to use the flow evaporator function. See subsection 3.6.4. Flow evaporator (Chill-
PAC/PAC).
17: Flow cond.
No
Yes
Select Yes to use the flow condenser function. See subsection 3.6.5. Flow condenser (Chill-
PAC/PAC - optional).
18: Level Control
Off
LP
HP
DX
Select LP or HP to use the LP or HP level control function. See subsection 3.6.6. Level control
and subsection 3.1.9. Set points for regulators.
Select DX in order to regulate an expansion valve controlling the liquid filling in the evapora-
tor according to the suction superheat set point.
When choosing LP, HP or DX it is not possible to configure any kind of oil cooling for screw or
reciprocating compressor. See 6.4.5. Oil system, 3: Oil cooling.
For reciprocating compressors it will still be possible to configure Water cooling. See subsec-
tion 6.4.5. Oil system, 5: Water cooling.
When choosing LP, HP or DX it is not possible to configure 13: By-pass start to Yes.
19: Ext PT100
Yes
No
Select Yes if the superheat calculation used in the DX regulation is based on a suction tem-
perature measurement from an external 4-20 mA PT100 transmitter.
This transmitter must be scaled -50°C to +-50°C, 4 to 20 mA.
Select No if the superheat calculation used in the DX regulation is based on the standard Suc-
tion temperature PT100 sensor.
20: Evolution (at present not available)
No
Yes
This configuration point enables a future “Evolution” chiller functionality.
21: Flow factor
0 to 10,000 m
3
/hour
Adjust the flow factor according to the installed flow measuring device. Only valid if COP ac-
tive = Yes. See the Unisab III COP manual for further information.
