efficiencies 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.
PROTOUCH™ CONTROL
The Combitherm PROtouch control features a simple,
graphics-based control panel that commands all the oven
functions. Access your titled recipes. Manual cooking by
time and temperature also are easily accomplished.
Intuitive interface - The Alto-Shaam PROtouch offers
a simple interface that commands all of the Combitherm’s
cooking functions. As the name implies, it is fully operable
by touch.
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.
Superior baking - The five-speed fan provides consistent
baking results. A moisture injection feature provides perfect
sheen and crust on breads and pastry items.
Multi-shelf timers - Track cooking time of different food
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.
Graphic controls - The highly visual
graphic-based control with logical
procedures ensure that correct steps
are followed every time.
An excellent memory - Access an
unlimited number of programmed
titled recipes that you’ve customized.
Each recipe can have up to 10
sequential steps.
HACCP data access -
CT PROformance™ ovens include a
downloadable HACCP function.
Absolute Humidity Control -
provides 0-100% humidity levels
allowing more control over the ideal
cooking environment and product
finish [patentpending].
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.

AUXILIARY FUNCTIONS AND FEATURES
PREHEAT FEATURE
The oven should be preheated before most cooking
functions. When cooking full loads, use a temperature
50°F (10°C) greater than the cook temperature in order
to recover from heat loss when the door is opened to add
food to the oven. For items that use the Steam mode, it
is necessary to use a preheat temperature lower than the
cook temperature in order to create the proper amount
of steam.

COOL DOWN FEATURE
The cool-down feature provides the operator with the
ability to lower the temperature of the oven compartment
at an accelerated pace. This function is useful when it is
necessary to immediately change from a high temperature
cooking function to a lower temperature function or to the
steam program. This function is also useful to help cool
the oven compartment in preparation for cleaning.
TIP: Always allow the oven walls to cool to a minimum of
140°F (60°C) before spraying the compartment with
oven cleaner.

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.

STEAM MODE CHEF OPERATING TIPS
This mode will steam a full or partial load of a single product,
or multiple products without transfer of avors. When
steaming multiple products, however, individual product
cooking times must be taken into consideration. The
STEAM
Perforated, 2-1/2" deep pans (65mm)
are particularly suitable for use in
this program mode. These pans will
provide a shorter cooking time and will
prevent product over-cooking at the
bottom of the pan.
Separate ice-encrusted vegetables
before steaming to ensure
even cooking.
A variety of products can be steamed
at the same time but attention must
be paid to the different cooking times
required for each food product.
When cooking by probe, the probe
must be inserted so that the tip is
positioned in the center of the food
mass. For liquid or semi-liquid foods,
suspend the probe in the center of the
product and secure the probe wire to
the edge of the container.
HIGH TEMP STEAM
High temperature steaming is suitable
for hearty, root-type vegetables such as
potatoes, turnips, carrots, and cabbage.
High temperature steaming provides
a cooking time which is approximately
10-percent shorter than the regular
steam mode temperature of 212°F
(100°C).
non-pressurized atmosphere of the Combitherm also
provides the ability to open the door during the steam mode
in order to monitor products more closely throughout the
steaming process.
LOW TEMP STEAM
The low temperature steam mode
will function whenever the oven
compartment temperature is below
212°F (100°C).
It will take longer to steam
products using the low temperature
steam mode.
Steaming sausages in low temperature
steam prevents cracked or peeling
skins.
Use low temperature steam for delicate
foods such as shrimp, sh, seafood,
crème caramel, and sous vide.
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 and convection
heat. In addition to shorter cooking times, this combination
of steam and heat offers less product shrinkage and more
moisture retention than obtained in a convection oven.

The Combination mode injects the optimum amount of
steam automatically. There is no need to select humidity
levels. Foods do not dry out. Flavors are retained with no
transfer of avors when mixing product loads.
Due to automatic steam adjustment, the door can be opened
at any time during a cooking operation. Be certain to observe
the safety warning when opening the oven door.
The Combination mode is particularly efcient when used
for baking, broiling, grilling, stewing, braising, and roasting.
When using the Combination mode, cooking temperatures
can be reduced 10- to 20-percent below the temperatures
used for conventional cooking methods.
Cooking time will be reduced approximately 40-percent
when cooking at the same temperature used for convection
oven cooking and up to 50- to 60-percent less time when
cooking at the same temperature used for a conventional
oven.
Food browning in the Combitherm begins at a cooking
temperature of approximately 250°F (120°C).
A higher cooking temperature results in heavier browning
but also results in greater product weight loss. To achieve
additional browning set humidity control into the product
procedure. Humidity control is particularly useful for adding
color to high moisture products such as chicken and other
poultry items or for additional browning of full loads and
other moist products.
The Combination mode provides even browning without the
necessity to turn the pans.
For more even cooking, do not cook in pans deeper than
4" (100mm).

that the tip is positioned in the center of the food mass. For

The Convection mode operates with hot circulated air within

consider using the Convection mode on a more limited basis.
