Selecting the Pressure / Flow Rate Display and Units
The Chiller can be set up to display either fluid pressure (in PSI or kPa) or flow rate (in GPM or LPM). Pressing
the Units/Menu Select Button briefly toggles through the available selections.
NOTE:
The metric pressure reading displayed must be multiplied by 100 for the actual kPa value.
NOTE:
The flow rate readout is intended as a reference only. If accurate flow readings are required, an
external flow meter is recommended.
Setting Operational Parameters / Limits
The Chiller’s various operational parameters, such as temperature, flow rate, and pressure alarm values, are all
user-adjustable. They are accessed by pressing and holding the Units/Menu Button until HL appears on the
Pressure/Flow Rate Display. Pressing and releasing the Units/Menu Button once HL appears allows you to scroll
through the various parameters; rotating the Select/Set Knob allows you to change the displayed setting. You can
accept the displayed value by either pressing the Select/Set Knob or allowing the display to timeout.
Operational parameter limit alarms will shut down the compressor, fan, pump, and heaters. Some temperature
values are only displayed and settable in ºC
NOTE:
Some parameters listed may not be included in your version of software.
NOTE:
The Ranges and Default Settings shown are for standard models. Ranges and Default Settings for
your unit may differ depending on the options selected.
