15.12. DELTA FUNCTION
The DELTA Function is an Auxiliary Function which operates with the temperature difference between the true core
temperature and the temperature of the chamber.
The Chamber Setting Temperature is always 50 ºC higher than the temperature recorded by the Core Probe. As the
value of the True Core Temperature increases, the Chamber Temperature Setting also increases automatically by
the same amount.
Turn the Core Probe Temperature Encoder to
select the required core temperature (for
example 70 ºC) shown on the display Core
temperature selected
Insert spike probe in food (for example 15 ºC)
indicated in the True core temperature.
The oven will heat up to 15 ºC+50 ºC = 65 ºC
and as the core temperature rises the Probe
Temperature + 50ºC will also rise, always with
a difference of 50 ºC.
When the core temperature reaches the
selected temperature of 70 ºC, the oven
chamber temperature should be 120 ºC and
an alarm will be heard.

15.13. COOL DOWN
COOL DOWN is a system for rapidly cooling the chamber. To activate this function and cool the cooking chamber,
proceed as follows:
- Close the door and press button COOL DOWN. Next open the door.
- The fan starts, but the heating is switched off and the COOL DOWN LED
lights up. When the chamber temperature falls to 45ºC, the process stops
automatically.
- The cooling cycle can be stopped by pressing the COOL DOWN button
again OR by closing the door, and the COOL DOWN indicator will go out.
Warning: Do not cool the oven by directly applying cold water in the tub.
SAFETY MEASURES: During this cycle the fan cover and the tray guides should be securely fastened in their
position.
15.14. HUMIDIFICATION
Humidification is an Auxiliary Function which provides moisture to the cooking process. This occurs
by spraying water over the heating elements (resistor or heat exchanger of the chamber burner),
causing the water to change to steam.
The moisture input only operates while the Humidification button is pressed in Start mode (in Stop
mode the signal is ignored).
Bakery products rise very well using this function thanks to the rapid entrance of moisture.
Soft shine to baked products.
It should be used for short periods of time.
