Service; Electronic Control Accuracy - Alto-Shaam 12-20W Installation Operation & Maintenance

ELECTRONIC CONTROL ACCURACY

The electronic control is a precise instrument and is
designed to offer trouble-free service. If you suspect
the temperature inside the warming cabinet does not
match the temperature indicated on the digital
display, after stabilizing, follow the instructions
listed below.
1. Check to make certain the unit voltage matches
the power source. A power source less than that
required to operate the unit will result in
inaccurate temperatures.
2. Verify the temperature inside the holding
compartment with a quality thermal indicator.
A. With the exception of the wire shelves,
completely empty the holding compartment.
B. Make certain the holding cabinet sensor,
located inside the holding compartment at
the left side of the unit, is completely clean.
C. Suspend the thermal indicator in the center
of the holding compartment.
D. Allow the temperature set on the electronic
thermostat to stabilize for a minimum of one
hour before comparing the digital display
with the reading on the thermal indicator.
DO NOT OPEN THE CABINET DOOR(S)
DURING THE TEMPERATURE
STABILIZATION PERIOD.
If the reading on the thermal indicator does not
match the digital display, there may be a problem
with the air sensor. See troubleshooting guide in
this manual, or call the factory service department
for advice.

SPECIAL FEATURES
HEAT RECOVERY
The patented SureTemp™ heat recovery system in
this unit will immediately compensate for any loss of
heat when the door is opened. in order to maintain a
more consistent cavity temperature, the control will
automatically apply heat to the unit's interior while
the door is open and for a short time after the door is
closed. If the door remains open for more than three
minutes, the solid state electronic control will sound
three rapid beeps every ten seconds until the door
is closed.
HACCP & KITCHEN MANAGEMENT SOFTWARE
These holding cabinets can be ordered equipped with
an optional serial communication interface. The
cabinets have the capability of being connected to the
internet via a Gateway device. This can provide
temperature recording data as well as setup and
diagnostic information which can be used for
HACCP documentation.
