You can adjust the following settings for your particular application or simply accept the default values.

High Temperature Limit (HL)

This menu item serves two functions. First, it establishes the maximum allowable set point temperature and thus

helps prevent an operator from inadvertently selecting a temperature set point above a pre-established value.

Secondly, it serves as a high temperature alarm, automatically activating both audio and visual alarm indicators if

the measured fluid temperature reaches the HL setting. This also causes the compressor, heater, fan, and pump

to turn off.

To change the high limit value, rotate the Select/Set knob until the desired value is displayed.

71.0

Low Temperature Limit (LL)

This menu item also serves a dual function. First, it establishes the minimum allowable set point temperature and

thus helps prevent an operator from inadvertently selecting a temperature set point below a pre-established value.

Secondly, it serves as a low temperature alarm, automatically activating both audio and visual alarm indicators if

the measured fluid temperature drops to the LL setting. This also causes the compressor, heater, fan, and pump

to turn off.

To change the low limit value, rotate the Select/Set knob until the desired value is displayed.

-46.0

High Ambient Temperature Limit (HA)

NOTE: This value is always set in °C.

This menu item protects the Chiller from overheating due to a high ambient temperature. Should the ambient

temperature rise above the limit value, the audio and visual alarms will activate, and the compressor, heater, fan,

and pump will turn off.

To change the high ambient temperature value, rotate the Select/Set knob until the desired value is displayed on

the temperature readout.

Maximum Fluid Pressure (FP)

This is the maximum allowable fluid pressure and can be set in either PSI or kPa (the LED adjacent to the display

indicates the active unit of measure). 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.

To change the fluid pressure limit value, rotate the Select/Set knob until the desired value is displayed on the

temperature readout.

NOTE: When FP first appears, the PSI LED will be lit. To view the FP value in kPa, press the Units/Menu

Button again. The FP will remain on the display, and the kPa LED will light up.
