Controls and function
Operating controls are located on a control panel mounted in the door of the upright freezers, and
on the console on the right side of chest freezers.
Every New Brunswick freezer is equipped with S.M.A.R.T. Plus™ diagnostic software, to help
identify the cause of a fault or setpoint variance.
This section describes the controls and function of the control panel, (see Fig. 4 on p. 15).

TEMP-ALARM
The TEMP-ALARM illuminates and the audible alarm sounds if
the freezer’s internal temperature is above/below the
user-selected alarm setpoints. The LED illuminates as soon as
the setpoint is passed. The high temperature audible alarm has
a programmable delay (see Setting the alarm delay on p. 23).
After the temperature returns to the normal range, the
TEMP-ALARM switches off and the audible warning stops.
Hint!
The audible alarm can be silenced by pressing the ALARM TEST/MUTE KEY. If the temperature
has not returned to normal range after the programmed time period, the audible warning will
sound again. This pattern will continue to repeat until the temperature returns to normal.
