5 USER INTERFACE
5.1 Preliminary notes
The followin operatin 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 operatin cycle)
- the “run” status (the device is powered, is on and an operatin cycle is in pro ress).
Hereon, the term "device switch-on" means the passa e from the "stand-by" status to the "on" status. the term "switch-
off" means passa e from the "on" status to the "stand-by" status.
If a power cut occurs durin the "stand-by" status or durin the "on" status, the device will re-propose the same status
when the power supply is restored.
If a power cut occurs durin 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 De ice 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 o to the STANDBY status.

EVCO S.p.A. EVFTFT618 | Installer manual ver. 2.2 | Code 144FTFT618E224
Pa e 16 of 62
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 settin
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 De ice On/Off
Operate as follows:
1. Press and release the ON/STAND-BY key.
5.4 The display
The display will be off durin the STANDBY status. The LEDs relative to the active keys are on.
Durin 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-makin ,
throu h the automatic mana ement of the complete mixture retarder-proofer cycle.
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 re ulation 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 stora e phase is the second phase of the automatic cycle.
Temperature re ulation 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,
provin phases and the day and time of provin end time desired for the mixture.
3. RECOVERY phase
The recovery phase is the third phase of the automatic cycle.
The temperature re ulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The
passa e from the stora e set-point (previous phase) to the recovery set-point can be radual with increase percenta es
established in the parameters pro rammin phase.
The relative humidity re ulation 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.

Pa e 18 of 62
4. PROVING phase
The provin phase is the fourth phase of the automatic cycle.
The temperature re ulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The
passa e from the recovery set-point (previous phase) to the provin set-point can be radual with increase percenta es
established in the parameters pro rammin phase.
The relative humidity re ulation 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 bakin delay phase is the fifth phase of the automatic cycle.
The bakin delay phase is always disabled but can be enabled both in the cycle settin phase and also with cycle in
pro ress by the final user.
The temperature re ulation is active and is NEUTRAL AREA, the work set-point is established by the final user.
The relative humidity re ulation 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 pressin the stop key for 3
seconds.
There are also 2 manual work cycles available; one MANUAL REFRIGERATION cycle (equivalent to a stora e but with
infinite duration) and a MANUAL HEATING cycle (equivalent to a provin cycle with infinite duration and without re ulation
steps).
To make these re ulations possible, the controller will therefore mana e the utilities set-up for coolin (compressor,
evaporator fan, defrostin , pump-down electrovalve), for heatin (heatin elements or operatin in heat pump mode),
humidification (steam enerator, humidifier) end dehumidification (dehumidification via extraction fan or via activation of
the coolin plant); the re ulations of each individual utility will be described in the followin chapters.
In addition to mana ement of the automatic and manual cycles, the controller envisions the possibility to mana e other
functions, such as:
-Pre-coolin mana ement
-"Delayed bakin " connection/disconnection mana ement
-Cabinet li ht mana ement
-Mana ement of 10 user pro rams
-Mana ement of 10 Favourite Pro rams
-Connection to RICS
-Host USB port mana ement on machine for: download/upload PROGRAMS, download/upload PARAMETERS and
download HACCP data.
