Introduction
Ecosmart® Technology
The Alto-Shaam Combitherm combination
oven/steamer employs Ecosmart operating
efciencies in the design and application of
all operating and programming functions.
Ecosmart operational characteristics include
the use of a water barrier to close the oven
compartment to the outside air. While maintaining a
non-pressurized atmosphere, the primary purpose of
the Ecosmart system is to prevent the steam and heat
generated within the oven compartment from freely
escaping to the outside.
The Ecosmart design displaces the air within the cooking
compartment and achieves a higher level of steam
saturation that offers quick-steaming at temperatures
above 212°F (100°C).
This guide is provided as an operational aid with
step-by-step instructions of the basic functions of the
Combitherm oven, along with the many other additional
features of the control.

pending].
Powerful tool - The PROtouch control plays an
important part in our continuous improvement
process. New features and abilities can be loaded to
your oven as they become available. Simply call our
Service Department for assistance.
Superior baking - The ve-speed fan provides
consistent baking results. A moisture injection feature
provides perfect sheen and crust on breads and pastry
items.

items in the same oven with multi-shelf timers. Time is
tracked in minutes and seconds.
On-board diagnostics - The PROtouch control includes
on-board diagnostic functionality with results displayed
right on the touch screen.
Two power levels: reduced power to manage kitchen
power peaks, and eco power for optimal oven efciency.

Auxiliary Functions and Features
Humidity Control Feature
The humidity control feature is an automatic
function designed to regulate humidity to provide
additional color to food as needed. This feature
is particularly useful for adding color to high
moisture products such as chicken and other
poultry, or for additional browning of full loads
and other moist products. In addition, this feature
may be used to add texture to fried items such
as french fries or breaded chicken. Humidity
control can be used in any cooking mode and can
be programmed into a cooking procedure.
Touch the nearest 10% increment on the le side
of the screen, and then adjust up or down using
the + or – icons.
0% humidity is the driest cooking environment
available. The percentage level chosen will
appear on the icon. In the illustration at right,
72% is shown.
Rapid Cool (available on boiler-free models only)
This function, when used with a program, rapidly
removes heat from the oven cavity. Swily move
from a high cooking temperature to a lower
temperature without overcooking your food.
Rest
This step allows you to pause the oven during a
program. The rest step is ideal for cold smoking
or automatic cleaning. Infuse your food with
smoke avor aer the actual smoking step has
stopped. When used during the cleaning process,
the oven cavity soaks for a specied time before
you move into the next step.
Door
The door function allows the user to program
a reminder—in the form of an animated door
opening and closing—that it is time to open the
door. This reminder may be programmed at the
end of a programmed segment or at the end of
the program.
Touch the check mark to
approve the value entered.

The Combination mode will prove to be the most versatile
and widely used mode the Combitherm oven has to offer.
It will produce the best possible results on the widest
variety of products — all within the shortest period of
time. The unique control function of this mode enables
the operator to roast or bake with a combination of steam
