5 USER INTERFACE
5.1 Preliminary notes
The following operating status exist:
- the “stand-by” status (the device is powered and is off)
- the “on” status (the device is powered, is on and is in stand-by for the start-up of an operating cycle)
- the “run” status (the device is powered, is on and an operating cycle is in progress).
Hereon, the term "device switch-on" means the passage from the "stand-by" status to the "on" status. the term "switch-
off" means passage from the "on" status to the "stand-by" status.
If a power cut occurs during the "stand-by" status or during the "on" status, the device will re-propose the same status
when the power supply is restored.
If a power cut occurs during the "run" status, the device will operate as follows when this is restored:
operation after cut-off of the power supply depends on parameter "P6"; if set at 0 the cycle will be interrupted, if set at 1
the cycle will be re-started and if set at 2 the cycle will only be re-started if the the power cut-off supply was less than the
time set by parameter "P5".
5.2 Device commissioning
Operate as follows:
1. Connect the device power supply. if parameter E9 is set at 1, the device will display the EVCO splash screen for 10
seconds, otherwise it will display a black screen for 10 seconds, after which it will go to the STANDBY status.
Page 15 of
62
EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224
2. Press and release the ON/STAND-BY (1) key.
If the duration of power supply cut-off was such to cause the clock error, the board will display the clock setting
screen directly. The controller does not control the coherence of the data entered, it is the user's job to control
the data are entered correctly.
5.3 Switching the Device On/Off
Operate as follows:
1. Press and release the ON/STAND-BY key.
5.4 The display
The display will be off during the STANDBY status. The LEDs relative to the active keys are on.
During the ON status, the device will display the date, real time, cabinet temperature and the possible functions that can
be selected.

6. OPERATION
6.1 Preliminary notes
The controller supplies a complete control for retarder-proofer cabinets or cells for confectionery and bread-making,
through the automatic management of the complete mixture retarder-proofer cycle.
MACHINE
START
An automatic retarder-proffer cycle is composed of 5 different phases with different temperatures, relative humidity, fan
speed and duration, which are performed one after the other and precisely:
1. BLOCK phase
The block phase is the first phase of the automatic cycle.
Temperature regulation is active and is neutral area, the temperature set-point, the humidity set-point (the control if
envisioned), the speed of the fans and the duration in hours and minutes of the phase are established by the final user.
Adjustment of the relative humidity depends on parameter rU4. If set at zero, humidity control is not envisioned in this
phase.
2. STORAGE phase
The storage phase is the second phase of the automatic cycle.
Temperature regulation is active and is neutral area, the temperature set-point, the humidity set-point (the control if
envisioned), the speed of the fans and are established by the final user.
Adjustment of the relative humidity depends on parameter rU4. If set at zero, humidity control is not envisioned in this
phase.
The duration of this phase is calculated automatically by the controller on the basis of the duration of the lock, recovery,
proving phases and the day and time of proving end time desired for the mixture.
3. RECOVERY phase
The recovery phase is the third phase of the automatic cycle.
The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The
passage from the storage set-point (previous phase) to the recovery set-point can be gradual with increase percentages
established in the parameters programming phase.
The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.
The duration in hours and minutes of the phase and the evaporator fan speed are established by the final user.
Page 17 of
62
EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224
4. PROVING phase
The proving phase is the fourth phase of the automatic cycle.
The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The
passage from the recovery set-point (previous phase) to the proving set-point can be gradual with increase percentages
established in the parameters programming phase.
The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.
The duration in hours and minutes of the phase and the evaporator fan speed are established by the final user.
5. BAKING DELAY phase
The baking delay phase is the fifth phase of the automatic cycle.
The baking delay phase is always disabled but can be enabled both in the cycle setting phase and also with cycle in
progress by the final user.
The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.
The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user, as is
the evaporator fan speed.
The duration of the phase is theoretically infinite, i.e. it ends when the cycle is interrupted by pressing the stop key for 3
seconds.
There are also 2 manual work cycles available; one MANUAL REFRIGERATION cycle (equivalent to a storage but with
infinite duration) and a MANUAL HEATING cycle (equivalent to a proving cycle with infinite duration and without regulation
steps).
To make these regulations possible, the controller will therefore manage the utilities set-up for cooling (compressor,
evaporator fan, defrosting, pump-down electrovalve), for heating (heating elements or operating in heat pump mode),
humidification (steam generator, humidifier) end dehumidification (dehumidification via extraction fan or via activation of
the cooling plant); the regulations of each individual utility will be described in the following chapters.
In addition to management of the automatic and manual cycles, the controller envisions the possibility to manage other
functions, such as:
- Pre-cooling management
- "Delayed baking" connection/disconnection management
- Cabinet light management
- Management of 10 user programs
- Management of 10 Favourite Programs
- Connection to RICS
- Host USB port management on machine for: download/upload PROGRAMS, download/upload PARAMETERS and
download HACCP data.
