1.1 Product description
Vcolor 539 is a split controller with a capacitive TFT touch-screen colour graphic display (5” or 7") for flush panel fitting and total
management of food processing cabinets or rooms for different types of products such as meat, charcuterie and cheese.
It has manual conservation cycles and automatic aging cycles (up to 30 sequential phases) whose duration, temperature, humidity and
ventilation can all be fully configured.
It is possible to set automatic air change and pause/work cycles, as well as managing optional sterilisation, oxygenation and smoking
processes either automatically or manually.
Standard 4-20 mA transducers (such as EVHP503) may be used to manage humidity or read the acidity level of a product; alternatively
humidity can be controlled using a dedicated probe T+RH EVTHP500 (RH 5-95% / T -20/ 0°C).

5AN OVERVIEW OF HE FUNC IONS
5.1 Automatic and manual cycles
The controller provides complete control for food processing cabinets or rooms for different types of products such as meat,
charcuterie, cheese and other types of product.
5.2 Settable features for each phase
An automatic aging cycle can consist of a maximum of 30 different sequential phases, for each of which the user can set the following
features:
5.2.1 Management of temperature, humidity, ventilation speed, duration
Regulation of temperature and humidity is carried out in the neutral zone. The resolution of the setpoint setting and the temperature
reading is 0.1°C, while the resolution of the setting and the humidity reading is 1 %RH.
Heating control can be deactivated by the user for the whole duration of the cycle in progress using the general cycle settings.
Humidity control can be deactivated by the user for some phases: by setting humidity under 0%, the "OFF" value or "humidity control
deactivated for the phase in progress" will be set (the icon will appear on the display, showing humidity control is not active).
The ventilation, depending on the type chosen by the OEM, may be SINGLE SPEED (in this case it cannot be regulated by the end
user), DOUBLE SPEED (in this case the user can select LOW or HIGH speed) or modulating through the external phase cutting module
EVDFAN1 (in this case the user can select the speed from the minimum settable by the user to 100%).
Cycle duration can be set from 0 minutes to 30days23h59' with a resolution of 1 minute.
By setting the cycle duration to INF (the equivalent of value 0), the phase will have infinite duration and no following phases will ever
be carried out.
5.2.2 Air change management
During the aging process, the air in the cabinet needs changing periodically to ensure it is always rich in oxygen in order to prevent
smells or impurities which could ruin the product.
The interval and duration of the air change fan are set by the user phase by phase.
For phases in which NO automatic air change is required (only manual), just set the activation interval to MANUAL (the equivalent of 0).

EVCO S.p.A. Vcolor 539 M & L | Installer manual ver. 1.0 | Code 144VC539E104
page 1 of 4
If the user also wishes to deactivate the MANUAL air change, just set the air change duration to OFF (the equivalent of 0) for the
desired phase.
5.2.3 Management of product rest intervals
During the aging process, products need frequent and long periods of complete rest, when the equipment does not regulate either the
temperature, humidity or ventilation inside the chamber.
During a rest phase, the only load that can be activated is the recirculation fan and this can be done either automatically or manually
(loads which do not concern regulation, such as light, obviously remain on or can be activated).
Product rest periods can be set by the user, phase by phase, in the following way:
- interval: how often the rest period takes place
- duration: how long the rest period lasts
- delay: how long after the beginning of the phase the first rest interval begins
- days: once the initial delay has elapsed, how many days the rest periods are repeated for, with the established interval and duration.
By setting the interval to MANUAL (the equivalent of 0), the rest period will only be manual.
By setting the duration to OFF (the equivalent of 0), manual rest period will also be disabled.
By setting the delay to 0', the rest period will begin immediately at the beginning of the phase.
The number of days can be set from 1 to 30.
5.3 Settable features for the aging cycle
As well as the individual features of each stage, the aging cycle has a number of special features which can be selected/deselected by
the user during the setting phase. These are:
5.3.1 Cabinet restart
When the "Cabinet restart” function is enabled at the end of the set aging cycle, a pop-up appears on the display and, by simply
touching it, the same aging cycle is restarted.
The next time an automatic programme is entered, the controller will return to the last cycle carried out which can easily be retrieved
by the user.
5.3.2 Heating control
By enabling/disabling the "Heating control” function, the heaters (and their connected loads) will be activated/deactivated for the whole
duration of the cycle if the cabinet temperature goes below the neutral zone value established.
If heating control is disabled, the icon on the display will stay on for the duration of the cycle.
5.3.3 Final holding
By enabling/disabling the "Final holding” function, the user decides if, at the end of the final phase in the cycle, the equipment must
maintain the temperature and humidity in the cabinet at the same values of the last phase before the cycle was STOPPED, or if it must
switch off all the regulation loads, losing control of the temperature and humidity.

EVCO S.p.A. Vcolor 539 M & L | Installer manual ver. 1.0 | Code 144VC539E104
page 19 of 4
5.3.4 Final air change
By enabling/disabling the "Final air change” function, the user decides if the equipment must carry out an air change cycle or not at the
end of the final phase of the cycle in progress. A final holding can be set to begin after the air change.
5.4 Other functions
During both automatic and manual aging cycles, a series of functions/loads can be activated manually by the end user to further
process/transform the products.
All these functions are activated/deactivated from parameter, therefore the function activation keys will only appear on the RUN screen
if they have been enabled.
5.4.1 Product sterilisation/oxygenation cycle
This cycle can be activated manually by the user during either an automatic or a manual aging cycle.
Parameter u1 establishes the type of icon to set, depending on the type of load connected: STERILISATION icon or OXYGENATOR icon.
Once the relevant key has been pressed, a pop-up screen will appear which will establish:
a) duration of the function (consisting of a sequence of Ton + Toff; duration in hh:mm with value 0 = UP TO MANUAL STOP)
b) activation time (in seconds)
c) switch-off time (in seconds)
When the switch-off time is set at 0 seconds, the output will be continuously active for the whole duration set by the user.
It is important to save the last value set by the user and repropose it at the next activation request.
The settings default is: duration = MANUAL, Ton = 1 0sec, Toff = 0sec
The activation of the function lasts for the duration of the cycle: a sterilisation/oxygenation cycle can be activated while an aging cycle
is taking place.
If the aging cycle changes phase, the sterilisation/oxygenation cycle continues.
If the aging cycle goes into the rest or air change phase, the sterilisation/oxygenation cycle is paused.
If the door is opened or there is a defrosting cycle, the sterilisation cycle will be SUSPENDED and will resume when the door is closed or
after the defrosting cycle and when the ventilation is reactivated.
If the aging cycle ends, the sterilisation/oxygenation cycle continues until the end of its counter time or until it is manually deactivated.
The STERILISATION output is only activated when the EVAPORATOR FAN IS ACTIVATED.
Temperature and humidity are regulated regularly. All the other outputs can be activated/deactivated.
The STERILISATION or OXYGENATION key will become one of 3 colours to indicate the activation, deactivation or pausing of the
function/output. They are:
U V U V U V
white icon key = function disabled
green icon key = function enabled and output activated
orange icon key = function enabled and output deactivated
5.4.2 Product smoking cycle
This cycle can be activated manually by the user during either an automatic or a manual aging cycle.
Once the relevant key has been pressed, a pop-up screen will appear which will establish the duration of the function (duration in
hh:mm with value 0 = UP TO MANUAL STOP).
It is important to save the last value set by the user as it will be reproposed at the next activation request.
The settings default is: duration = MANUAL.
The activation of the function lasts for the duration of the cycle: a smoking cycle can be activated while an aging cycle is taking place.
If the aging cycle changes phase, the smoking cycle is stopped.
If the aging cycle goes into the rest or air change phase, the smoking cycle is paused.
If the door is opened or there is a defrosting cycle, the smoking cycle will be SUSPENDED and will resume when the door is closed or
after the defrosting cycle.
If the aging cycle finishes, the smoking cycle is stopped. When the cycle is terminated, it is not possible to launch a smoking cycle.
Temperature and humidity are regulated regularly. All the other outputs can be activated/deactivated.
The SMOKING key will become one of 3 colours to indicate the activation, deactivation or pausing of the function/output. They are:

page 20 of 4
white icon key = function disabled
green icon key = function enabled and output activated
orange icon key = function enabled and output deactivated
5.4.3 Manual rest cycle
The operation of this cycle is described in the section "Management of product rest intervals". Similarly to what happens in the
sterilisation/oxygenation and smoking cycles (see previous sections), the relative key will become one of 3 colours to indicate the
activation, deactivation or pausing of the function/output.
5.4.4 Manual air change cycle
The operation of this cycle is described in the section "Air change management". Similarly to what happens in the
sterilisation/oxygenation and smoking cycles (see previous sections), the relative key will become one of 3 colours to indicate the
activation, deactivation or pausing of the function/output.
5.4.5 Manual defrosting
Pressing the appropriate key sets off the manual defrosting cycle. There is also an automatic defrosting cycle which is active at intervals
during all the automatic and manual phases. Similarly to what happens in the sterilisation/oxygenation and smoking cycles (see
previous sections), the relative key will become one of 3 colours to indicate the activation, deactivation or pausing of the
function/output.
5.4.6 Light on/off
This manually switches the light on/off. The switching on/off of the light can also be associated with the digital door switch input status.
Similarly to what happens in the sterilisation/oxygenation and smoking cycles (see previous sections), the relative key will become a
different colour to indicate the activation or deactivation of the function/output (without the orange output status “paused").
