To clear an Alarm Low warning, correct the problem or decrease the Alarm Low temperature value.
Limit Low Temperature — This feature provides additional safety and protection by allowing a
selectable lower temperature limit set point.
If you attempt to enter a set point value that exceeds the Limit Low value, the audible alarm will
sound and a Warning message will flash on the display when the Limit Low value is reached. You
will also be prevented from decreasing the set point value any further.
To clear a Limit Low warning, enter a lower value for the Limit High or increase the control
temperature set point.
If the Limit Low value is exceeded during operation (due to a Controller fault, excessive cooling load,
etc.), a Fault message will appear on the display and power to the heater and condenser will be
disconnected. The pump will continue to run.

4.11.7 Selecting the Pump Speed
Pump speed is selected from the Pump menu. This display shows the current pump speed setting.
The number to the right of the bar is for reference only and is useful in providing similar pumping
characteristics when using multiple baths. See Section 2.1 for approximate pump max
pressures/flow rates.
Limit High Set Point. Bath
set point temperature cannot
be raised above this value.
Limit Low Set Point. Bath set
point temperature cannot be
lowered below this value.
If bath temperature moves
above or below
Limit
values, alarm activates and
power to the heater and
condenser is disconnected.
High Temperature Alarm Set Point.
Alarm activates if bath temperature
rises to this value.
Low Temperature Alarm Set Point.
