Menu Item Description Choices / Ranges Default Setting
HL High Temperature Limit — Limits the maximum allowable
set point temperature. Audio and visual alarm indicators are
activated when the measured fluid temperature reaches the
HL temperature setting.
NOTE: EHL will appear on the display if the High Limit value
is set below the current set point.
5° to 131°F
(-15° to +55°C)
95°F (35°C)
LL Low Temperature Limit — Limits the minimum allowable
set point temperature. Audio and visual alarm indicators are
activated when the measured fluid temperature reaches the
LL temperature setting.
NOTE: ELL will appear on the display if the Low Limit value
is set above the current set point.
-4° to 80°F
(-20° to +27°C)
39°F (4°C)
HA High Ambient Temperature Limit — Maximum ambient
temperature limit. Displayed and settable only in ºC. Should
the ambient temperature rise above the HA value, the audio
and visual alarms will activate and the compressor, heater,
fan, and pump will turn OFF.
NOTE: The rated cooling capacity on air-cooled chillers is
dependent on an ambient temperature below 104°F (40°C);
performance will decrease as ambient temperature rises.
CAUTION: Continuous operation at ambient temperatures
above 104°F (40ºC) is not recommended for any air-cooled
or water-cooled chiller.
30° to 75ºC
Always displayed
and set in °C
45 ºC
FP Maximum Fluid Pressure — Maximum allowable fluid
pressure; settable in either PSI or kPa. Should the fluid
pressure rise above the maximum fluid pressure value, the
audio and visual alarms will activate and the compressor,
heater, fan, and pump will turn OFF.
NOTE: The Chiller also incorporates a built-in pressure
regulated bypass valve. It will maintain a maximum outlet
pressure by diverting flow of the process fluid to the
reservoir. The bypass valve may be adjusted by the
customer.
CAUTION: Maximum operating pressure for the Chiller is
100 PSI (6.9 bar). Different pumps have different maximum
operating pressures.
10 to 100 PSI
0.68 to 6.8 (x100) kPa
Reference:
0.68 = 68 kPa
6.8 = 680 kPa
10 psi = 68.9 kPa
100 psi = 689 kPa
100 PSI
6.8 x 100 kPa
(680 kPa)
FL Minimum Flow Rate — Minimum allowable flow rate;
settable in either GPM or LPM. Should the fluid flow rate
drop below the minimum value, the audio and visual alarms
will activate, and the compressor, heater, fan, and pump will
turn OFF.
0 to 50 GPM
0 to 190 LPM
0 GPM
0 LPM
Lb Lower Band — This sets how many degrees the process
temperature can fall below set point before the compressor
will turn OFF. It is displayed and settable in °C only.
1.0° to 5.0°C
Always displayed
and set in °C
2.0°C
