1INTRODUCTION
1 1 Introduction
Vcolor 318/328 is a range of stylish controllers for managing
different types of top-floor ovens.
Available in split version, the user interface consists of a 5-
inch (M) or 7-inch (L) capacitive F touch-screen graphic
display in glass, 65K colours, 800 x 480 pixel resolution and
IP65 protection for easy cleaning.
hese controllers are suitable for different types of electric
ovens due to the independent management of the power and
the temperature at the top and on the floor of the oven. he
model Vcolor 318 manages top-floor heaters by electro-
mechanical relays, while the model Vcolor 328 has 2 12 VDC
outputs for managing external SSRs.
hey have a complete steam management system
(generation, injection and venting) in both automatic and
manual modes, the functions "weekly programmed switch-on",
"cooking timer", "programs" and energy-saving strategies.
he user interface installed from behind using threaded studs
enables it to be placed flush with the panel thus making it fit
perfectly with the design of the unit.

Control module measurements and installation
he pictures below show the measurements of the device control module; measurements are expressed in mm (inches).
Installation is on a flat surface with spacers.
2 4 Installation precautions
- Ensure that the working conditions for the device (operating temperatures, humidity, etc.) are within the set limits. See
section 15 ECHNICAL SPECIFICA IONS.
- Do not install the device close to heat sources (heaters, hot air ducts, etc.), equipment with a strong magnetic field (large
diffusers, etc.), in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations or shocks.
- Any metal parts close to the control module must be far enough away so as not to compromise the safety distance.
- In compliance with safety regulations, the device must be installed properly to ensure adequate protection from contact
with electrical parts. All protective parts must be fixed in such a way as to need the aid of a tool to remove them.
- ensure that the thermocouple is properly insulated from contact with metal parts or use already insulated thermocouples.

Example of connection of a motorised venting solenoid valve.
he diagram below shows functioning with the following parameters set.
u2 = 140 (14 seconds) pause time for cam to run
u3 = 10 (1 second) motor activation time for short milling output
u4 = 30 (3 seconds) motor activation time for long milling output
3 3 Precautions for electrical connection
- Do not use electric or pneumatic screwdrivers on the terminal blocks of the device.
- If the device has been moved from a cold to a warm place, the humidity may cause condensation to form inside. Wait about
an hour before switching on the power.
- Make sure that the supply voltage, electrical frequency and power of the device correspond to the local power supply. See
section 15 ECHNICAL SPECIFICA IONS.
- Disconnect the device from the power supply before doing any type of maintenance.
- Connect the power cables as far away as possible from those for the signal.
- o reduce reflections on the signal transmitted along the cables connecting the user interface to the control module it is
necessary to fit a termination resistor.
- Ensure that the thermocouple is properly insulated from contact with metal parts or use already insulated thermocouples.
- For repairs and for further information on the device, contact the EVCO sales network.

6USER INTERFACE
6 1 Initial information
he interface has the following operating modes:
•"ON": the device is powered up and switched on;
the loads can be switched on
•"S AND-BY": the device is powered up but
switched off by the software; the loads are switched
off
•"OFF": the device is not powered up; the loads are
switched off.
6 2 Splash screen
When the control module is powered up, it defaults to the
EVCO splash screen for a few seconds.
o disable it, set parameter e0 to 0.
6 3 Stand-by screen
Following the splash screen, the user interface displays the
screen chosen by parameter e2.
e2 = 0 e2=1
Briefly press the ON/OFF key
to switch on the device; pressing it for 3 seconds, switches it
off.
N.B. OFF status can be forced by activating multi-purpose
input 1 (see parameter i5) and it can be linked to output K5 by
parameter u5 (u5=1).
If the "weekly programming" function is enabled by the
parameter (C5 = 1), the Planning key will also be displayed
top left
making it possible to set weekly programmed switch-ons (see
section 8).
Set-up key
displayed top right, makes it possible to access the date and
time settings and to configure the parameters (see section 10
Configuration).
6 4 ON screen
6 4 1 Initial information
Depending on the construction features of the oven, and
according to whether it has 1 or 2 analogue inputs, the
controller can be regulated in two different ways that have to
be correctly set with parameter P2.
P2 = 0 1 analogue input (chamber probe)
P2 = 1 2 analogue inputs (top probe and floor probe)
6 4 2 Ovens with 1 analogue input
In this type of oven, the separate temperature management
for the top and the floor is obtained by setting the percentage
of power delivered above (top) and below (floor). he
percentages can be set individually and are not affected by
each other. he following screen is displayed:
he settings for ovens with 1 analogue input are as follows.
•he chamber setpoint (shown in smaller type to
the side of the chamber temperature)

6 4 3 Ovens with 2 analogue inputs
In this type of oven, the separate temperature management
for the top and the floor is obtained by setting two different
temperature setpoints: one for the top and one for the floor.
he following screen is displayed:
he settings for ovens with 2 analogue inputs are as follows.
•op setpoint (shown in smaller type to the side of
the top temperature)
•Floor setpoint (shown in smaller type to the side of
the floor temperature)

Press this key to activate the steamer and the functions linked
to this will be displayed. If the steamer is not yet up to
temperature, the steam On/Off key lights up yellow and steam
injection is disabled.
If the steamer is up to temperature, the steam On/Off key
lights up green and steam injection is enabled.
he MANUAL key makes possible persistent steam injection
(see parameter t0).
he AU O key makes it possible to activate/deactivate cyclical
steam injection during one cooking cycle or, if the cycle is not
in progress, to pre-set this.
he SE -UP key makes it possible to access the automatic
steam injection setting bar.
he following settings are possible.

only switches the light on if the device is on; the light goes out
when the device is switched off.
6 4 8 Energy-saving function
he energy-saving key
activates the energy-saving function, except when rapid
heating is in operation. For more detail, see paragraph 9.2.3.
6 4 9 Rapid heating function
his key is only visible when configured with an analogue
input. he rapid heating key
activates the function making it possible to reach the
regulation setpoint more quickly by activating the top and floor
heaters at full power. his key is not active when energy-
saving is in progress.
6 5 Expert Screen
he Expert Menu key
gives access to a screen with additional functions and
information on the status of the device.
If no cooking cycle is in progress, the following functions can
be activated.

inputs, relay outputs)
•Select recipe from recipe book.
•Save a recipe in the recipe book.
•Add phase to a recipe.
•Delete phase from a recipe.
•Manual activation of suction hood
•View and reset alarms
If a cooking cycle is in progress, only the following functions
can be activated.

inputs, relay outputs)
•Manual activation of suction hood
•View and reset alarms (only if in progress)
o return to the ON screen (and in general, to return to the
previous page at any level of settings you are in), touch the
Back key which can be seen top left.
6 5 1 Clock and alarms
he Clock field shows the current date and time.
If an alarm is active, the following icon will appear in place of
the Clock field.
6 6 Screen Saver
Following a period of inactivity of the keypad, which can be set
using parameter e3, the display changes to the screen saver in
order to enable the cooking chamber temperatures to be seen
more easily.
If a cooking cycle is in progress, devices with 1 analogue input
will display the percentages set and the chamber temperature,
while devices with 2 analogue inputs will display the top and
floor temperatures, the cooking timer, the active phase
