1INTRODUCTION
1.1 Introduction
Vcolor 679/689 is a controller for retarding-proofing or proofing cabinets and rooms which delivers high performance and precision
regulation, thanks to a modulating output which gives control of up to ten evaporator fan speeds. The evaporator fan can also be
modulated using an EVCO inverter. In the 689 models, the modulating output can also be set to control variable speed compressors.
By simply setting a parameter, the controller can be configured to manage retarding-proofing and proofing automatic cycles. Variables
such as temperature, humidity, fan intensity and duration can be managed independently for each phase. As well as three-phase
proofing cycles (re-awakening, proofing and baking delay), with blocking and holding added in the retarding-proofing cycles, there are
also manual cycles such as heating for proofing and cooling/pre-cooling/heating for retarding-proofing.
The controller’s innovative programmable platform gives manufacturers the freedom to personalise the graphic skin and programmes
and add new languages. All they have to do is compile an ODS file and upload it using a flash drive to the USB port on the user
interface. Users can store up to 100 programmes, match them to a set of preloaded images and move them to the favourites.
Users can interact remotely with their equipment and start up/stop working cycles using the EPoCA® cloud platform 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 of our website.
The controller has an open frame board and a remote user interface which consists of a 5-inch (M) or 7-inch (L) capacitive TFT touch-
screen graphic display in glass which is installed horizontally either semi-recessed into the front or flush with the panel.

4RETARDIN -PROOFIN OR PROOFIN OPERATION
4.1 Initial information
Vcolor 679/689 is a controller which, by simply setting a parameter, can be configured to manage retarding-proofing cabinets and
rooms (E1 = 1) or proofing cabinets and rooms (E1 = 0). All the cooling regulations are for retarding-proofing only; care must
therefore be taken when configuring the controller for proofing (E1 = 0), that no parameters are set for cooling (see section 14.
PARAMETERS).
Automatic management of the complete dough cycle consists of three phases in the proofing configuration (re-awakening, proofing and
baking delay), plus two more for retarding-proofing (blocking and holding). There are also manual cycles such as heating for proofing
and cooling/pre-cooling/heating for retarding-proofing.
This manual gives instructions how to use the controller, only pointing out when there are differences between the two configurations.
5FIRST-TIME USE
5.1 Operating modes
The controller has the following operating modes:
- “OFF” (no power to the device);
- “STAND-BY” (the device is powered but switched off);
- “ON/HOME” (the device is powered, switched on and awaiting start-up of an operating cycle);
- “RUN” (the device is powered, switched on and running an operating cycle).
Terminology: “device switch-on” means going from “stand-by” to “ON” and “device switch-off” from “ON” to “stand-by”.
If there is a power outage, when power is restored the device will return to the mode set before the failure.
5.2 Operating the device
Follow these instructions to operate the device:
1. Install the device as shown in section “MEASUREMENTS AND INSTALLATION”, taking all the precautions mentioned in
paragraph .6 “Installation precautions”.
. Make the electrical connection as shown in section 3 “ELECTRICAL CONNECTION”, taking all the precautions mentioned in
paragraph 3.3 “Precautions for electrical connection”.
3. Connect the power supply to the device: the device will show a splash screen for 10 seconds.
Once loading is complete, the device will display the mode it was in before being powered down:
- stand-by screen, press the central area to move to the Home screen;
