1INTRODUCTION
1.1 Product description
Vcolor 378 is a controller or electric bread and pizza deck ovens with a remote touch-screen user inter ace in 5- or 7-inch glass which
its in per ectly with the design o the unit. It can control up to 5 levels through an RS-485 network o power boards connected to a single
user inter ace.
It manages steam (generation, injection and venting) in both automatic and manual mode and independently regulates the power and
temperature o the top, loor and ront heaters. Being able to control the temperature o the ront heater is particularly important or
certain baked goods.
The controller has an oven cleaning unction which uses pyrolysis, a sel -cleaning mechanism that does not require chemical detergents
as ood residue is oxidised at high temperature.
The controller can save up to 99 recipes; each recipe can have up to 8 phases, each with independent settings or duration, temperature,
steam injection cycles, venting and suction. Recipes can be compiled in an ODS ile (complete with pictures in BMP or GIF ormat) and
uploaded to the controller using a USB lash drive, thanks to the innovative programmable plat orm which allows users to customise their
recipes and add new languages. Recipes can also be altered, overwritten and saved directly rom the display and two di erent recipes
can be switched on and o or every day o the week.
Users can interact remotely with their equipment and start up/stop working cycles using the EPoCA® cloud plat orm with Wi-Fi or Ethernet
connectivity (which also enables alternative or parallel control through MODBUS TCP). For more details, compare all the connectivity
options in the Technical Data table and consult the Management and Monitoring Products/Systems and the Connectivity Products/Devices
sections o our website.

5.4 ON screen
5.4.1 Initial information
Depending on the construction eatures o the oven, and
according to whether it has 1 or 2 analogue inputs, the
controller can be regulated in two di erent 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 loor probe)
Control o the ront heater can also be added and is regulated
in two di erent ways:
•1 dedicated analogue input (P4=1 in con igurations with
r12=0, 1, 3, 4, 5)
•by setting a percentage relative to the working percentage
o the top heater (P4=0 with con iguration r12=2); the
working percentage, set by parameters r16 and r17, will
always be calculated considering the set working
percentage o the top heater as the maximum value.
5.4.2 Oven regulated by one chamber probe
In this type o oven, separate temperature management or the
top and the loor is obtained by setting the percentage o power
delivered above (top) and below ( loor). The percentages can
be set individually and are not a ected by each other. The
ollowing screen is displayed:

EVCO S.p.A. Vcolor 378 | Installer manual ver. 1.0 | Code 144VC378E104
Page 19 o 50
The settings or ovens with one chamber probe are as ollows:
•chamber setpoint (shown in smaller type to the side
o the chamber temperature)
•top power
•loor power
•cooking timer
•recipe selection
•mode (economy or rapid)
•venting
•hood
•chamber light
•steam generator
•steam injection
•stand-by
5.4.3 Oven regulated by one chamber probe + one
probe for floor front
This con iguration di ers rom the previous one as it includes a
dedicated probe (P4=1) to manage the ront heater. The
ollowing screen is displayed:
On the basis o parameter r12, the temperature o the ront can
be:
- absolute (r12=0): in this case parameters r13, r14 and r15
are relevant
- relative to the chamber setpoint (r12=1): in this case the ront
setpoint cannot be changed but is considered the same setpoint
as the chamber; a relay must also be con igured as the ront
loor heater (uxc=3).
5.4.4 Oven regulated by one chamber probe + floor
front % adjutment
I the oven is regulated by a single probe and the ront heater
is not controlled by a temperature probe but a percentage
relative to the top cycle time (P4=0, r12=2, in this case
parameters r16 and r17 are relevant), the ollowing screen is
displayed:
5.4.5 Oven regulated by one chamber probe + one
probe for top/floor front
This oven con iguration is used when there is a chamber probe
(P2=0) and a ront probe (P4=1), with the chamber and ront
setpoints set individually but the percentages o the power
delivered to the top/ loor o the ront the same as those
delivered to the top/ loor o the chamber (r12=5).
Four relay outputs must be con igured in this setting: chamber
top heater (uxc=1), chamber loor heater (uxc=2), ront loor
heater (uxc=3) and ront top heater (uxc=13).
5.4.6 Oven regulated by two probes (top and floor)
In this type o oven there are two probes which are independent
o the top temperature and the loor temperature. Separate
temperature management or the top and loor is obtained by
setting two di erent temperature setpoints: one or the top and
one or the loor. The ollowing screen is displayed:

EVCO S.p.A. Vcolor 378 | Installer manual ver. 1.0 | Code 144VC378E104
Page 20 o 50
The possible settings or ovens with 2 probes (top and bottom)
are as ollows:
•top setpoint (shown in smaller type to the side o the
top temperature)
•loor setpoint (shown in smaller type to the side o
the loor temperature)
•cooking timer
•recipe selection
•mode (economy or rapid)
•venting
•hood
•chamber light
•steam generator
•steam injection
•stand-by
5.4.7 Oven regulated by two probes (top and floor) +
one probe for floor front
This con iguration di ers rom the previous one as it includes a
dedicated probe (P4=1) to manage the loor ront heater. The
ollowing screen is displayed:
On the basis o parameter r12, the temperature o the ront can
be:
- absolute (r12=0): in this case parameters r13, r14 and r15
are relevant;
- relative to the top setpoint (r12=3): in this case the setpoint
o the ront cannot be changed but is considered the same
setpoint as the top;
- relative to the loor setpoint (r12=4): in this case the setpoint
o the ront cannot be changed but is considered the same
setpoint as the loor; a relay must also be con igured as the
loor ront heater (uxc=3).
5.4.8 Status bar
When the device is switched on, the oven is already operating
and the outputs are active according to the required settings.
The status bar shows the unction being per ormed by the oven:
