Normal Operation
NOTE:
The Chiller incorporates a special “lockout” feature that can be enabled to prevent unauthorized or
accidental set point and other operational changes. This feature is described in detail under “
Enabling /
Disabling the Local Lockout
.” It should not be enabled until all operational parameters have been set.
Selecting the Temperature Unit (°C or °F)
The LEDs adjacent to the Temperature Display indicate the unit (°C or °F) used for Temperature Displays.
To change from °C to °F or vice versa, proceed as follows:
To change to °F — Place the Power Switch on the rear of the instrument in the OFF position. Press and
hold the Units/Menu Select Button while returning the Power Switch to the ON position.
To change to °C — Place the Power Switch on the rear of the instrument in the OFF position. Press and
hold the Power Button on the front panel while returning the Power Switch to the ON position.
IMPORTANT:
All user settings, except baud rate and calibration offset, return to the original factory defaults
when the temperature unit is changed. The Chiller’s temperature set point and various alarm settings should
be reset to the desired values.
Displaying and Adjusting the Set Point
Press the Select/Set Knob on the front panel. The current set point temperature will be displayed, and the decimal
point at the bottom right of the display will flash, indicating that the temperature can be changed.
Rotate the Select/Set Knob until the desired set point temperature is displayed. The setting is accepted after the
Select/Set Knob is pressed a second time or automatically after a few seconds of inactivity.
NOTE:
Temperature set point cannot be changed when the local lockout is enabled. See “
Enabling /
Disabling the Local Lockout”
