As an option, your chamber may include the TempGard IV feature with the Watlow

Controller. The circuit operation description is explained in the Alarm And Shutdown Circuit
section of this manual. This configuration section serves as a brief reference guide. For

Controller, please reference the user manual.
When properly configured, the lower display of the control will be blank and the upper display
will show the actual temperature as measured by the control's RTD sensor, when conditions
are within the alarm settings. If an out of limit condition occurs, the lower display will flash "HI"

"LO"
depending on the particular fault.
