1 INTRODUCTION
1.1 Introduction
Vcolor 338 L is a controller with elegant design for managing
“top-class” electric ovens for gastronomy and confectionery
(including rotary ones).
It is available in split version and can be integrated both
mechanically and aesthetically into the unit, the user interface
is composed of a 7 inch TFT touch-screen colour graphic
display and guarantees an IP65 protection rating, for easy
cleaning.
It is able to manage ventilation in "on / off" and modulating
mode (in this case it is necessary to also use an external
speed regulator), with inversion of the direction of rotation of
the fan.
It also manages the steam (injection and air vent), both in
automatic and manual mode, the cleaning, with liquid
detergent or tablet, and the “weekly programmed switch-on”
and “programs” functions (the latter to memorise the cooking
settings in a program, with the purpose of successively
selecting and performing it).
This is to be installed on the back of the panel, with studs, for
flush mounting

6 MANAGEMENT OF UTILITIES
6.1 Preliminary notes
This paragraph illustrates the activity of the utilities during
normal operation.
To know the main consequences of an alarm, see chapter 16
“ALARMS”.
6.2 Temperature regulation
The output is on until the environment temperature reaches
the work set-point and is switched back on when the
temperature drops below the value established with the
parameter r0 (i.e. "working set-point - r0").
To set the work set-point, see paragraph 8.2 “Setting the
cooking cycle”; to set the configuration parameters, see
paragraph 16.2 “Setting the configuration parameters”.
6.3 Steam injection
The steam generation mode depends on parameter t0, as
follows:
-
-
-
The parameter t1 establishes the cycle time for the injection of
the steam generated in direct mode and the parameter t2 the
duration of the injection of the steam generated with the same
mode corresponding to the maximum humidification.
The parameter t6 establishes the cycle time for the injection of
the steam generated with external humidifier and the
parameter t7 the duration of the injection of the steam
generated with the same mode corresponding to the maximum
humidification.
To set the humidification, see paragraph 8.2 “Setting the
cooking cycle”; to set the configuration parameters, see
paragraph 16.2 “Setting the configuration parameters”.
if the parameter t0 is set at 0, the steam will be
generated in direct mode.
if the parameter t0 is set at 1, the steam will be
generated with an external humidifier
if the parameter t0 is set at 2, the steam will be
generated in combined mode (i.e. direct and with
external humidifier); in this case the temperature
established with parameter t12 determines the
temperature above which the steam generated in
direct-mode will be injected and below which the
steam generated with an external humidifier will
be injected (referring to the temperature detected
by the environment probe).
6.4 Air Vent
The utility managed by the air vent output depends on
parameter u1, as follows:
-
-
if the parameter u1 is set at 0, the utility will be
an on/off electrovalve
if the parameter u1 is set at 1, the utility will be a
motorised electrovalve
The air vent is opened automatically on conclusion of each
phase of a cooking cycle.
To set the duration of the automatic air vent opening, see the
paragraph 8.2 “Setting the cooking cycle”.
The air vent is also opened/closed by touching the “manual”
area.
6.5 Room light
The environment light is switched on/off by touching the
reference area: .
6.6 Technical compartment fan
The technical compartment fan is on until the temperature of
use of the control module reaches the temperature established
with parameter F6 and is switched back on when the
temperature rises above that established with parameter F7
(i.e. “F6 + F7”).
To set the configuration parameters, see paragraph 16.2
“Setting the configuration parameters”.
6.7 Fan
The type of ventilation management depends on parameter
F0, in the following way:
-
-
-
-
If parameter F0 is set at 0, 1 or 2, parameter F1 will establish
the duration of fan switch off due to the inversion of the
direction of rotation of the same and parameter F2 that of fan
switch-on for every direction of rotation.
If parameter F0 is set at 3, the parameters F4 and F5 will
establish the minimum and the maximum fan speed, the
parameter F8 will establish the minimum fan speed that can
be set on a cooking cycle.
To set the fan speed, see paragraph 8.2 “Setting the cooking
cycle”; to set the configuration parameters, see paragraph
16.2 “Setting the configuration parameters”.
if the parameter F0 is set at 0, ventilation will be
managed in “on/off” mode and at single speed
if the parameter F0 is set at 1, ventilation will be
managed in “on/off” mode and at single speed and
with inversion of the fan rotation direction
if the parameter F0 is set at 2, ventilation will be
managed in “on/off” mode and at dual speed and
with inversion of the fan rotation direction
if the parameter F0 is set at 3, ventilation will be
managed in modulating mode and with inversion
of the fan rotation direction

EVCO S.p.A.
Vcolor 338 L | Installer manual ver. 2.0 | Code 144VC338LE204
6.8 Cooking fumes reduction
The cooking fumes reduction is active until the temperature
detected by the fumes probe reaches the temperature
established with parameter t13 and is turned back on when
the temperature rises above the one established with the
parameter t14 (i.e. "t13 + t14", only if the fumes probe is
enabled, i.e.if parameter P3 is set at 1).
To set the configuration parameters, see paragraph 15.2
“Setting the configuration parameters”.
6.9 Outputs management for
special cleaning cycles
The controller has 4 relay outputs to manage two different
types of cleaning:
-
-
-
At the start of every cleaning cycle the room light turns on
automatically, and can be turned off and back on again at any
time with the dedicated switch.
Below is a detailed description of the two types of cleaning:
Cleaning cycle with liquid detergent, with no water
recycling:
There are 4 management relays, each with a different
function:
-
-
-
-
The cleaning cycle goes through 4 linked phases in cascade.
Phase 1 - Precleaning:
The oven temperature is raised to the precleaning level (w0
parameter) If the room temperature is lower, the heating
output will be activated together with the ventilation, while at
the same time closing the air vent.
If the temperature is higher than the set one, the controller
will keep only the ventilation on, the air vent will remain open
and a pop-up message will request the door to be opened in
order to facilitate the cooling of the chamber.
When the temperature lies within the "precleaning w0 -
precleaning activation hysteresis authorisation (w1)"setpoint
range , the air vent closes, the door must be closed (if
previously opened) and the controller will activate the K13
relay (mains water solenoid valve) for w2 minutes.
At the same time, the K11 relay: water drain pump will also be
activated. Ventilation remains active for the whole duration of
the phase, the heating output will keep the set temperature
constant.
Cleaning cycle with liquid detergent, with no
water recycling;
Cleaning cycle with tablet detergent, with
water recycling;
Cleaning cycle disabled.
K13 Relay: Mains water solenoid valve;
K12 Relay: Liquid detergent injection pump;
K11 Relay: Water drain pump;
K10 Relay: Liquid rinse aid injection pump;
At the end of the w2 time, the resistors, ventilation, water
solenoid valve and, after a w16 delay the water drain pump
will be turned off.
Phase 2 -Cleaning:
The cleaning phase starts at the end of the precleaning. After
time F1 (fan deceleration) has elapsed, the K12 (liquid
detergent injection) relay is activated for w4 seconds.
After the w4 time has elapsed, there is a w5 minutes pause to
allow the detergent to act.
After the w5 time has elapsed, the machine starts heating
again, with active ventilation, bringing the chamber up to the
cleaning temperature (parameter w3); after the t11 time has
elapsed, the controller will start injecting steam in the
chamber (with 100% setting) for a total time of w6 minutes.
After the w6 time has elapsed, the controller commands a
brief rinse of the chamber by activating the K13 (mains water
solenoid valve) relay for w7 seconds.
The K11 and K13 relays are activated for 32 seconds.
Phase 2 of the cleaning cycle can be repeated:
-
-
-
according to the settings input by the final user during the
cycle selection/setting phase.
Phase 3 - Rinse aid:
The "Rinse aid" phase starts after the end of the cleaning
cycle.
The K10 relay: "liquid rinse aid injection pump" is activated
for w9 seconds, followed by a pause of w10 seconds to allow
the rinse aid to become effective.
After the w10 time has elapsed, the machine starts heating
again, with active ventilation, bringing the chamber up to the
rinse aid action temperature (parameter w8); after the t11
time has elapsed, the controller will start injecting steam into
the chamber (with 100% setting) for a total time of w11
minutes.
1 time (soft cleaning)
2 times (medium cleaning)
3 times (hard cleaning)

Important: with the w9=0 setting the "rinse aid" phase
is bypassed entirely.
Phase 4 - Rinse:
The rinse phase starts at the end of the Rinse aid cycle.
The machine (with active ventilation) will be brought to the
rinse temperature (parameter w12), the controller will activate
relay K10 (mains water solenoid valve) for w13 minutes. At
the same time, the K2 relay (water discharge pump) will also
be activated.
Ventilation remains active for the whole duration of the phase,
the heating output will keep the set temperature constant.
After the w13 time has elapsed, the mains water solenoid
valve will be turned off and after a w16 delay the water drain
pump will be deactivated.
Phase 5 - Drying:
The drying phase starts at the end of the rinse cycle.
The machine (with active ventilation) will be brought to the
drying temperature (parameter w14) for w15 minutes and the
air vent will open. After this time has elapsed, the cleaning
cycle will end, all outputs will be turned off, including the room
light and the machine will go to the ON screen.
Cleaning cycle stop
If the cycle is stopped manually during the precleaning, rinse
or drying phase, the cycle stops immediately.
If the cycle is stopped manually during the cleaning or rinse
aid phase, the machine will go to the rinse cycle and stop at
the end of that phase.
During any phase, the black-out alarm will reset the ongoing
phase.
If the door is opened at any time, the cycle is paused and
starts again when the door is closed.
Cleaning cycle with tablet detergent, with water
recycling;
There are 4 management relays, for:
-
-
-
-
This kind of cleaning can also be supported by a dedicated
probe to check the drain temperature of the water used for
cleaning, as it should not exceed 60-75°C in order to be
drained into the sewers (national regulation).
To enable the water drain temperature control, the relevant
probe (rather than the fumes one) must be turned on with
parameter P3=2.
K13 relay: condenser mains water solenoid valve
K12 relay: water recirculation pump
K11 relay: condenser water drain pump
K10 relay: not used
The cleaning cycle with tablet allows a choice to be made
among 4 different types:
-
-
-
-
The "Rinse" cleaning type is a special sequence cycle, while
the other cycle types differ in the number of repetitions of the
cleaning phase carried out.
The following picture shows the "CLEANING" selection screen,
where it will be possible to select one of the four types of
cleaning
Cycle selection and start
If a RINSE cycle is selected and started, the machine will go
immediately into pre cleaning mode.
If one of the other three available types is selected, instead,
the controller will ask for the input of the number of detergent
doses to be injected in the chamber:
-
-
-
After injecting the detergent (the machine does not check
whether the detergent has actually been injected), press the
START button again to start the precleaning phase.
Phase 1 - Precleaning:
The oven temperature is raised to the precleaning level (w0
parameter) If the room temperature is lower, the heating
output will be activated together with the ventilation, while at
the same time closing the air vent.
If the temperature is higher than the set one, the controller
will keep only the ventilation on, the air vent will remain open
and a pop-up message will request the door to be opened in
order to facilitate the cooling of the chamber.

When the temperature lies within the "precleaning w0 -
precleaning activation hysteresis authorisation (w1)"setpoint
range , the air vent closes, the door must be closed (if
previously opened) and the controller will activate the K13
relay (mains water solenoid valve) for w2 minutes, during
which the condenser will be charged with water and filled to
allow the recirculation pump to collect the water needed for
the various cleaning phases.
Ventilation remains active for the whole duration of the phase,
the heating output will keep the set temperature constant.
After the w2 time has elapsed, the machine operation will vary
according to the type of cycle selected: RINSE or CLEANING
cycle.
Phase 2A - RINSE
The selected cycle is performed at the end of the Pre cleaning
phase.
The counting of one w10 minutes cycle starts now: during this
time, the "condenser mains water inflow solenoid valve",
"Direct steam injection" and "water recirculation pump"
outputs will be activated with the ventilation on at maximum
speed.
After the w10 time has elapsed, the machine will go back to
the HOME screen and keep the Water Discharge Pump output
in operation for the time w9 in order to empty the condenser.
If the door is opened or the STOP key pressed, the cycle will
be immediately interrupted and the machine will go back to
the HOME screen.
Phase 2B - Cleaning Preparation
The oven is brought to the cleaning preparation temperature
(parameter w8) with 100% humidification for w11 minutes,
and in the meanwhile the K13 (condenser mains water inflow
solenoid valve) relay will also be activated.
Once the correct temperature is reached, all the outputs
except the ventilation one will de deactivated until the
temperature has fallen below the w18 temperature; then the
regulation, steam injection and mains water injection tasks will
be taken up again. After the w11 time has elapsed, the cycle
will go on to the next phase.
Phase 3B - Cleaning
At the end of the cleaning Preparation phase, the cycle will
launch the cleaning phase.
The cleaning phase sets a w5 time during which the oven is
brought to the cleaning temperature (parameter w3),
ventilation is always active at full speed, the recirculation
pump is started and will pump the hot water from the
condenser into the chamber flooding the detergent tablets.
In this phase there is no steam injection.
After w5, a w6 time is set. The machine disconnects all utilities
(except power) to allow the detergent to act.
The Duty Cycle comprising w5 and w6 will be repeated:
-
-
-
During the entire cleaning phase, if enabled through the P3
parameter and if the value of the Water Drain probe exceeds
the maximum water drain set point (parameter w19), the
controller will activate the Mains Water Injection output to
allow the condenser temperature to drop.
The differential for this adjustment is fixed and equal to -10°C,
that is to say, water inflow stops when the temperature read
by the Water Drain sensor drops by 10°C as against the
maximum water drain e set point (parameter w19).
At the end of the number of cycles set for the current one, the
machine will go on to the next phase.
Phase 4B - Rinse
This phase has a duration of w13, during which time the
condenser mains water injection, the direct steam injection
and the maximum speed ventilation will be active.
No heating phase and no recycling phase are entailed. After
the w13 time has elapsed, the cycle will go on to the next
phase.
Phase 5B - Drying
The drying phase starts at the end of the rinse cycle.
The machine is brought to the drying temperature (parameter
w14) and with the ventilation on at maximum speed for w15
minutes, after which the cycle ends and the machine goes
back to the HOME screen.
Cleaning cycle stop:
If the cycle is stopped manually during the 1, 2A, 2B or 5B
phases, the machine will stop immediately.
If the cycle is stopped manually during the 3B phase, the
machine will go on to the 4B phase and then will stop at the
end of the 4B phase. If the cycle is stopped manually during
the 4B phase, the cycle will continue with the ongoing phase
and then will stop.
If the door is opened at any time, (from the moment in which
the desired temperature has been attained during phase one
with the closing of the air vent at the end of phase 5), this will
immediately interrupt the cycle and reset the machine to the
HOME screen.
A black-out alarm triggered during any phase will reset the
running phase
3 times if the cleaning cycle is
SOFT;
6 times if the cleaning cycle is
MEDIUM;
9 times if the cleaning cycle is
HARD;

6.10 User interface variant for
ROTOR ovens management
The ROTOR management controller differs from a COMBI one
due to the additional presence of:
-
-
Management of the motor rotation control relay output
and rack limit switch digital input
The motor rotation output is activated automatically at the
start of the oven preheating phase .
It will be possible to stop or restart the rotation at any
moment, with the relevant motor rotation/stop key in the user
interface; the motor will stop at the next forthcoming
activation of the limit switch input, which indicates the position
allowing the rack to be extracted after opening the door.
If the limit switch input is fault, incorrectly wired or not
installed (e.g., for rotor ovens with non removable rack), the
rack will stop after a maximum time determined by parameter
k2.
If the door is opened while the rack is rotating, the output
stops immediately (without waiting the limit switch activation
and the expiration of the maximum time period), to avoid any
hazard for the operator.
With the door closed, parameter k1 will establish whether the
rack starts to rotate again automatically or remains still in the
position it was before the door opening.

8 COOKING CYCLE
8.1 Preliminary notes
Every cooking cycle is preceded by preheating (on condition
that Delta T cooking has not been set; the work set-point is
relative to the work set-point during the first phase of the
cooking cycle, i.e. "work set-point during the first phase of the
cooking cycle + work set-point during preheating").
During pre-heat, the fan is switched-on at maximum speed.
When the temperature detected by the environment probe
reaches the work set-point, the buzzer is activated for 3 s.
The opening and closing of the door causes the passage to the
first phase of the cooking cycle.
Every cooking cycle is made up from a minimum of one to a
maximum of six phases; on conclusion of a phase, the device
moves automatically to the next.
For every phase, the device can manage the following
settings:
-

the work set-point is an absolute value)
with Delta T (only if the needle probe is enabled,
i.e. if parameter P2 is set at 1; the phase has
duration until the temperature detected by the
needle probe reaches the core set-point and the
work set-point is a delta referred to the
temperature detected by the needle probe, i.e.
“temperature detected by the needle probe +
Delta T set-point)
core (only if the needle probe is enabled, i.e. if the
parameter P2 is set at 1; the phase has duration
until the temperature detected by the needle
probe reaches the core set-point and the work set-
point is an absolute value)
the work set-point (only if timed or core cooking
has been set)
the Delta T set-point (only if Delta T cooking has
been set)
the humidification

EVCO S.p.A.

15.3 Application scheme
The burner module EVCLE302XXE interacts with electronic ignition control boards for atmospheric burners such as "Honeywell
4565"series (and similar) and with variable speed centrifugal fans with PWM control signal+ feedback (HALL sensor).
15.4 Operation
During the heating phase, the controller will activate the relevant room or boiler heating outputs, as well as the relevant burner, whose
heating power is managed proportionally to the work set point trough the centrifugal fan speed control.
The burner activation procedure is the following:
1. Pre-ventilation phase: the burner speed will rise to the value determined by parameter b2 for the room burner or by
parameter b9 for the boiler burner and it will remain constant for k 10 seconds.
2. Ignition phase: once pre-ventilation time is over, the speed stability is checked through the feedback of the Hall sensor and
the burner control unit is activated by starting the relevant relay (room or boiler heating). The flame will be detected through
the digital input and the heating phase will start.
3. Heating phase: the burner speed will rise to the value required by the regulation to heat the oven.
Such speed is proportional to the difference between the temperature and the work set point inside the proportional band
given by parameter b3 for the room or b10 for the boiler. The speed may vary from a minimum value given by parameter b1
for the room or b8 for the boiler, to a maximum value given by b0 for the room or b7 for the boiler.
page 42 of 66
EVCO S.p.A.
Vcolor 338 L | Installer manual ver. 2.0 | Code 144VC338LE204
15.5 Errors handling
Ignition phase:
If no flame is detected during ignition phase, the burner will maintain the ignition speed.
Heating phase:
If no flame is detected during heating phase, the activation relay is turned off, the fan returns to the ignition speed for 10 seconds and
after 20 seconds the ignition attempt is repeated.
Room/boiler burner fault alarm:
If the ignition control board activates the room/boiler burner fault digital input, a recovery procedure is performed. The procedure
consists in 3 ignition attempts before signalling the alarm.
Room burner alarm
The room burner fan speed is constantly checked through the Hall input. If the speed set for the room fan burner differs more than
parameter b5 from the Hall sensor feedback for a time longer than parameter b6, the alarm is signalled.
Boiler burner alarm:
The boiler burner fan speed is constantly checked through the Hall input. If the speed set for the boiler fan burner differs more than
parameter b12 from the Hall sensor feedback for a time longer than parameter b13, the alarm is signalled.
