7.2.4 Front heater
As well as the top and floor heaters, the front heater can also
be configured (P4=1); this heating element can be controlled in
different ways according to parameter r12.
7.2.5 Energy-saving function
The energy-saving function enables consumption to be reduced
and it is activated using the
input 2, if parameter i7 is set at 2, and it will remain active until
the input is deactivated. The maximum duration of the energy-
saving function is given by parameter c8.
•
Devices with one analogue input
The function cannot be activated in these devices if the
"rapid heating" function
The reduction in consumption is achieved by lowering the
percentage of power delivered to the top and floor by
setting parameter c9. This percentage can also be set by
applying prolonged pressure to the key. The ratio is as
follows:
power in ES= power set * c9/100
To access this function, press the
•
Devices with 2 analogue inputs
The reduction in consumption is achieved in these devices
by inhibiting the activations of the relay outputs at the
same time.
For ON-OFF regulation, the switch-on cycle periods are set
in seconds by parameter r8. The switch-on time for each
load will be half that period, r8/2 seconds, and switch-ons
will be separated in time so as to avoid overlapping.
With PI regulation, overlapping activation of the relays will
automatically be inhibited.
In this configuration, the key is always present on the main
screen.
7.3 Steamer management
Steam generator operation depends mainly on parameter P3
(enable steam injection) and can be:
•
0 = Manual
•
1 = Remote
•
2 = Thermostatic
•
3 = Disabled
Switching on the steamer can also be managed automatically
using parameter t6 (automatic steamer switch-on when the
oven is switched on) or using the On/Off steam key.
7.3.1 Manual steam regulation (P3 = 0)
Once steamer management is enabled, the steam generator
relay output is always active and steam injection is always
enabled.
Manual injection using the steam key is always enabled.

7.3.2 Remote steam regulation (P3 = 1)
Once steamer management is enabled, the steam generator
relay output is always active.
Steam injection is enabled if the multi-purpose input has been
activated, setting i5 to 1.
Manual injection using the steam key depends on the
configuration of parameter t12.
When the steamer is activated and the digital input not yet
activated, the steamer and manual steam injection keys flash
(if t12=1 only the steamer key flashes).
7.3.3 Thermostatic steam regulation (P3 = 2)
Once steamer management is enabled, the steam probe
activates thermostatic steam regulation.
The ON-OFF regulator parameters are as follows
•
t1 = steam setpoint
•
t2 = t1 differential
Steam injection (automatic and manual with t12=0) is enabled
as soon as the steam setpoint is reached (steamer up to
temperature). Injection (automatic and manual with t12=0) is
disabled if the temperature detected by the steam probe falls t3
degrees below the setpoint.
If t12=1, only manual steam injection is allowed, regardless of
steam temperature.
When the steamer is activated and the steam temperature
setpoint not yet reached, the steamer and manual steam
injection keys flash (if t12=1 only the steamer key flashes).
7.3.4 Steam injection mode
The following parameters make it possible to personalise steam
injection management
CONFIGURATION PARAMETERS):
•
t0 = steam injection activation mode: acts on the
manual steam injection key function
•
t4 = enables constraint between cyclical steam
injection and cooking timer start-up
•
t5 = enables constraint between cyclical steam
injection and the cooking timer stop.
7.4 Suction hood management
The suction hood can be activated manually using the key
below, according to the configuration of the phase of the recipe,
or automatically on activation of the door switch input.
The hood is always off when the controller is in stand-by.
7.4.1 Suction hood management with door switch
input
Door switch input activation is always shown on the display.
