• if the instrument has been taken from a cold place to a hot place, the
humidity could condense inside; wait for about one hour before
applying power
• check that the power supply voltage, the frequency and the electric
operational power of the instrument correspond with those of the
local power supply
• disconnect the power supply before performing any type of maintenance
• supply the probes with protection able to isolate them from any
contact with metal parts or use isolated probes
• do not use the instrument as a safety device
• for repairs and information regarding the instrument, contact the
Evco sales network.
2 PRELIMINARY CONSIDERATIONS
2.1 Preliminary considerations
The instrument can be configured to function with 1 measurement
input (default, chamber probe) or with 2 measurement inputs (top
probe and floor probe). If functioning with 1 measurement input it is
however possible to enable a second probe (steam probe) to subordinate the injection of steam at the temperature of the same.
Functioning with 1 measurement input allows to independently set
the power distributed to the top to that distributed to the floor. Functioning with 2 measurement inputs allows to independently set the
top and floor work temperatures.
The utilities managed by the digital outputs (i.e. relays K1 ... K6) are the
following:
RELAY MANAGED UTILITY
K1 top
K2 floor
K3 can be set (default chamber light)
K4 airhole
K5 steam injection
K6 can be set (default steam generator)
To set the type of functioning (with 1 measurement input rather than
2) see paragraph 4.1. However, to set the utility managed by relay K3
and relay K6 see paragraph 4.2.
2.2 Management of the utilities
Top.
If functioning with 1 measurement input:
• the output is switched on in cyclical mode, preferably when the
floor output is off (the parameter c1 establishes the cycle time. The
procedure given in paragraph 4.4 can be used to set the duration
of output switch-on, intended as a percentage of the time established with parameter c1)
• the cyclical activity is subject to the chamber temperature (chamber
probe), to the work set-point and parameter r0.
If functioning with 2 measurement inputs:
• the output activity depends mainly on the top temperature (top
probe), the top set-point and parameter r0.
Floor.
If functioning with 1 measurement input:
• the output is switched on in cyclical mode, preferably when the top
output is off (the parameter c1 establishes the cycle time. The procedure given in paragraph 4.4 can be used to set the duration of
output switch-on, intended as a percentage of the time established
with parameter c1)
• the cyclical activity is subject to the chamber temperature (chamber
probe), to the work set-point and parameter r0.
If functioning with 2 measurement inputs:
• the output activity depends mainly on the floor temperature (floor
probe), the floor set-point and parameter r6.
Chamber light.
The output is activated in manual mode.
Through the multifunction input it is also possible to activate the out-
put in remote mode.
Airhole.
The output is activated in the following conditions:
• before the conclusion of the cooking timer count (of the time estab-
lished with the parameter c5), for the time established with param-
eter c6
• in manual mode, for the time established for parameter c7.
Steam injection.
The output activity depends mainly on parameter t0.
Through the multifunction input it is also possible to activate the out-
put in remote mode.
Steam generator.
If functioning with 1 measurement input:
• if the steam probe is not enabled, the output is activated in manual
mode
• if the steam probe is enabled, the output is enabled in manual mode,
after which the activity of the same will depend on the temperature
of the steam (steam probe), the steam set-point and parameter t3.
If functioning with 2 measurement inputs, the output is activated in
manual mode.
Alarm.
The output is activated during a temperature alarm.
Through the multifunction input it is also possible to activate the out-
put in remote mode.
Cooking timer.
The output is activated during the cooking timer count.
Acoustics.
The output is activated in the following conditions:
• before the conclusion of the cooking timer count (of the time estab-
lished with the parameter c9), for the time established with param-
eter c4
• during an alarm or an error, with continuous contribution.
On/Stand-by.
The output is activated during the “on” state (see paragraph 3.1).
In spite of the fact that the instrument can manage the 10
utilities stated in this paragraph, there are 6 digital out-
puts available. Make sure that the desired utility is man-
aged by the instrument (see paragraph 2.1).
3 USER INTERFACE
3.1 Preliminary considerations
The following functioning states exist:
• the “on” state (the instrument is powered and on: the regulators can
be on)
• the “stand-by” state (the instrument is powered but switched off via
software: the regulators are off)
• the “off” state (the instrument is not powered).
Successively, the term “switch-on” means the passage from the standby state to the on state. The term “switch-off” means the passage from
the on state to the stand-by state.
When powered, the instrument re-proposes the state that it was in
when the power supply was disconnected.

6 STEAM GENERATOR
6.1 Preliminary considerations
The steam generator allows to subordinate the steam injection to its
own state.
If functioning with 1 measurement input, if the steam probe is not
enabled, pressing the
and keys for 1s will cause the steam
generator to switch on and successive pressing causes its switch-off;
steam injection is allowed on condition that the steam generator is on.
If functioning with 1 measurement input, if the steam probe is not
enabled, pressing the
and keys for 1s will enable the steam
generator, after which the activity of the same will depend on the
temperature of the steam (steam probe), the steam set-point and pa-
rameter t3 (successive pressing of the keys causes the steam generator
to be disabled);
steam injection is allowed on condition that the tem-
perature of the steam is above that established with the steam set-point
or at the minimum. Once the steam set-point has been reached, above
the “steam set-point - t4”.
If functioning with 2 measurement inputs, pressing the
and
keys for 1s will cause the steam generator to switch on and successive
pressing causes its switch-off;
steam injection is allowed on condition
that the steam generator is on.
If the steam generator is not managed by any digital output , pressing
the
and keys will cause the display of the “no” indication for
1s in the lower part of the display.
In this case, steam injection is always
allowed.
7 STEAM INJECTION
7.1 Preliminary considerations
The functioning mode of the steam injection depends on parameter
t0.
If the parameter t0 is set at 0, pressing the
key causes the injection
of steam for the time established with parameter t2 or for the entire
duration that the key is pressed. The parameter t1 establishes the mini-
mum time that can pass between the two successive injections.
If the parameter t0 is set at 1, pressing the
key will enable the
automatic injection of the steam (in cyclical mode: parameter t2 estab-
lishes the duration of the injector switch-on and parameter t1 estab-
lishes the duration of switch-off).
Using the multifunction input, it is also possible to cause the same
effect caused by pressing the
key in remote mode.
Steam injection is subordinate to the steam generator state (see para-
graph 6.1).
7.2 Quick setting of the parameter t2
• make sure that the instrument is in on state and that no procedure is
in progress
• press
and : the upper part of the display will show “t2”, the
lower part the corresponding value and the LED
will flash.
The parameter t2 can be set between 1 and 250 ds.

parameter t0 is set at 0)
• make sure that the instrument is in on state and that no procedure is
in progress
• press
: the LED will switch-on and the injector will be acti-
vated, both for the time established with parameter t2 or
for the entire duration that the key is pressed.
The injector must not be deactivated in manual mode.
7.4 Enabling of automatic steam injection (only if pa-
rameter t0 is set at 1)
• make sure that the instrument is in on state and that no procedure is
in progress
• press
: the LED will switch-on and the injector will be acti-
vated in cyclical mode according to that established with
parameters t1 and t2 (until the key is pressed again).
8 AIRHOLE
8.1 Preliminary considerations

• press
: the LED will switch-off.
9 ECONOMY
9.1 Preliminary considerations
The economy allows to reduce the power supplied to the top and the
power supplied to the floor by switching an output on when the
other is off.
If functioning with 1 measurement input, when the function is in
progress the top output and the floor output are switched on for half
of the duration of the switch-on set using the procedure given in
paragraph 4.4 (intended as a percentage of the time established with
parameter c1).
If functioning with 2 measurement inputs, when the function is in
progress, the top output and the floor output are switched-on alter-
nately for half the time established with parameter c1.
When the time established with parameter c10 has passed, the func-
tion is interrupted.
Through the multifunction input it is also possible to activate the
economy function in remote mode.
If the rapid heating function is in progress, the economy function
cannot be activated.
9.2 Economy activation
• make sure that the instrument is in the on state, that no procedure is
in progress and no rapid heating function is in progress
• press
When the function is in progress the LED
and for 1s.
will flash for 1s every 4s.
9.3 Economy interruption in manual mode
• make sure no procedure is in progress

10 RAPID HEATING (only if functioning with 1 meas-
urement input)
10.1 Preliminary considerations
The rapid heating allows to reach the work set-point as quickly as
possible, supplying 100% of the power both to the top and the floor
(i.e. excluding switch-on of the top and floor outputs in a cyclical way
with benefit to switch-on in continuous mode).
When the temperature of the chamber reaches the “work set-point -
temperature established with parameter c3” value, the function is in-
terrupted.
If the economy function is in progress, the rapid heating cannot be
activated.
10.2 Rapid heating activation
• causes the event established with parameter c2:
- if c2 = 1, press
for 1s (make sure that the instrument is in the on
state, that no procedure is in progress and the economy function is
not is progress)
- if c2 = 2, pass from the stand-by state to the on state
- if c2 = 3, press
for 1s (make sure that the instrument is in the on
state, that no procedure is in progress and the economy function is
not is progress) or pass from the stand-by state to the on state.
If parameter c2 is set at 0, the function cannot be activated.
When the function is in progress the upper part of the display shows
“F-F” alternately to the quantity established with parameter P5.
10.3 Interruption of rapid heating in manual mode
• make sure no procedure is in progress
• press
for 1s.
