Vcolor 279 - Application manual
Introduction
Vcolor 279 is a controller for refrigerated units and has 9 sealed
relays (which can be expanded to 13) to meet the most sophisticated
management needs in sectors such as laboratory refrigeration.
Regulation and reading accuracy is guaranteed by 3-point probe
calibration and access to controller functions is hierarchically
subject to user identication to increase the level of protection.
The controller interacts with a backup module to manage
emergencies, ensuring that temperature readings are always
recorded in the built-in data-logger, even in the event of a power
failure.
Featuring intuitive navigation with real-time trend graphs, the
controller’s innovative programmable platform allows the user
to personalise the graphic skin and add new machine interface
languages.
Upon request, the controller can also be equipped with Wi-Fi
connectivity so it can interact remotely with the unit through the
EPoCA® cloud platform.
Available in a 5- or 7-inch split version with a capacitive colour TFT
touch-screen graphic display, the user interface can be installed
ush with the panel, thus making it t perfectly with the design of
the unit.

Vcolor 279 - Application manual
Vcolor 279 solution
The Vcolor 279 is available in the split version with a control module combined with a 5-inch (Vcolor 279 M) or 7-inch (Vcolor
279 L) user interface.
This basic conguration can be connected to a series of optional modules illustrated below, increasing its functions and
making Vcolor 279 a complete control solution that can be customised to everyone’s needs.
Backup module
The backup module can be connected to the RS-485 network and must be equipped with a backup battery of the user’s
choice. It gathers information about:
Backup battery status:
- if a backup battery is installed or not and if it is faulty
Mains and module voltage status:
- information about the real-time status of the mains voltage
- no mains voltage alarm
Reading of the product probe (acts as a backup in the event of a power failure to the controller) that can be connected to the
module:
- information about the value detected by the Pt1000 probe
I/O expansion
The I/O expansion can be connected to the RS-485 network and has 4 fully congurable digital outputs. It enables the user
to control 4 more loads, compared to the 9 available on Vcolor 279.

EVlink Wi-Fi module
EVlink Wi-Fi is a hardware module with built-in Wi-Fi connectivity that can be connected to the RS-485 port of the user
interface to enable remote management and monitoring through the Internet using the EPoCA system.
