4.8.1 Manual activation of operation for low or high
percentage of relative humidity (but EVX201 and
provided parameter F0 is set to 5)
• make sure that the keyboard is not locked and that no other proce-
dures are in progress
• press the SET and the UP keys for 4 sec: the display will show “rhL”
(operation for low percentage of relative humidity) or “rhH” (opera-
tion for high percentage of relative humidity) for 10 sec.
To restore the normal display before the operation is complete:
• press a key.
Activation of the operation for a low or high percentage of relative
humidity can be done using parameter F6.
If parameter F0 is not set to 5, pressing the SET and the UP keys will
cause the display of the following message “- - - -“ for
1 sec.
4.8.2 Display of type of operation in progress (for low or
high percentage of relative humidity, but EVX201
and provided that parameter F0 is set to 5)
• make sure that no other procedure is in progress
• press and release the SET and the UP keys: the display will show
“rhL” (operation for low percentage of relative humidity) or “rhH”
(operation for high percentage of relative humidity) for 10 sec.
To restore the normal display before the operation is complete:
• press a key.
If parameter F0 is not set to 5, pressing the SET and UP keys will cause:
• the display of the message “- - - -“ for 1 sec if the keyboard is not
locked
• display of the label “Loc” for 1 sec if the keyboard is locked..
4.9
Manual switching on/off of the cell light (EVX204,
EVX214, EVX205 and EVX215 only and provided
that parameter u1 and/or parameter u11 is set to 0)
• make sure that no other procedure is in progress
• press and release the AUXILIARY key : the LED light will switch
on/off.
Using the door microswitch it is also possible to switch on/off the cell
light by remote; see also parameter u2.
If parameter u1 is set at 0 (i.e. the utility managed by the fourth output
is the cabinet light) and parameter u11 is set at 2 (i.e. the utility managed
by the fifth output is the auxiliary output), holding the AUXILIARY
key down for 2 s will cause the switch-on/off of the multipurpose LED
and of the auxiliary output.
4.10 Switching on the demisting resistors (EVX204,
EVX214, EVX205 and EVX215 only and provided
that parameter u1 and/or parameter u11 is set to 1)
• ensure that the instrument is switched on and that no other proce-
dure is in progress.
• press the AUXILIARY key for 2 sec: the multifunction LED will light
up and the resistors will be switched on, both for the amount of time
established with parameter u6.
Manually switching off the demisting resistors is not permitted (that is,
before the time established with parameter u6 expires).
4.11 Manually switch on/off of the Auxiliary output
(EVX204, EVX214, EVX205 and EVX215 only and
provided parameter u1 and/or parameter u11 is set
to 2)
• ensure that the keyboard is not locked and that no other procedure
is in progress
• press and release the AUXILIARY key.
Using the multifunction input it is also possible to remotely switch on/
off the auxiliary output.
If parameter u1 is set at 2 (i.e. the utility managed by the fourth output
is the auxiliary output) and parameter u11 is set at 0 (i.e. the utility
managed by the fifth output is the cabinet light), holding the
AUXILIARY key down for 2 s will cause the switch-on/off of the
cabinet light LED and of the cabinet light.
If the auxiliary output has been switched on manually, then it can also
be switched off manually (similarly, if the auxiliary output has been
remotely switched on, then it can only be switched off in the same
manner); see also parameter u2.
4.12 Energy Saving (but EVX201)
During function Energy Saving the working setpoint is increased of
the temperature you have set with parameter r4 and the evaporator
fan is turned on cyclically, on condition that parameter F0 has value
1 or 2 (parameter F13 sets the time the fan remains turned off and
parameter F14 the time it remains turned on).
Once the time you have set with parameter i10 has passed (without
activations of the door switch digital input and on condition that the
cabinet temperature has reached the working setpoint) function En-
ergy Saving is activated automatically (as long as the input will be
activated).
4.12.1 Activation/deactivation of function Energy Saving
with effect on the compressor only (EVX204, EVX214,
EVX205 and EVX215)
Through the multipurpose input it is possible to activate/deactivate
function Energy Saving at a distance.
Function Energy Saving can be activated in real time too, to the time
you have set with parameter HE1; in this case the duratin of the func-
tion can be set through parameter HE2.
4.13 Locking/unlocking the keyboard

HACCP FUNCTION
6.1
Preliminary notes
EVX201, EVX203, EVX204, EVX205 and EVX215:
The instrument is able to store up to 3 HACCP alarms.
The instrument provides the following inoformation:
• the critical value
• the alarm duration (from 1 min to 99 hours and 59 min, partial if the
alarm is in progress).
CODE ALARM TYPE (CRITICAL VALUE)
AL
minimum temperature alarm (the minium cell tempera-
ture during any alarm of this type)
AH
maximum temperature alarm (the maximum cell tempera-
ture during any alarm of this type)
id
door microswitch input alarm (the maximum cell tempera-
ture during any alarm of this type; see also parameter i4
Important Notes:
• the codes are displayed in the order shown in the table
• the instrument stores the minimum and maximum tem-
perature alarms provided the temperature associated
with the alarm is that of the cell (parameter A0 = 0)
• the instrument updates the information regarding the
the alarm provided the critical value of the new alarm is
more critical than that stored alarm or provided the infor-
mation has already been displayed.
• if the instrument is switched off, no alarms will be stored.
When the problem that caused the alarm disappears, the display is
restored to normal operation.
The HACCP LED provides information regarding the HACCP alarm
storage status; see paragraph 8.1.
For EVX214 and EVX215:
The instrument is able to store up to 9 HACCP alarms, after which the
most recent alarm will substitute the oldest.
The instrument provides the following information:
• critical value
• the date and time the alarm was signaled
• the duration of the alarm (from 1 min to 99 hours and 59 min, partial
if the alarm is in progress).
CODE ALARM TYPE (CRITICAL VALUE)
AL
minimum temperature alarm (the minimum temperature
of the cell during the alarm)
AH
maximum temperature alarm (the maximum temperature
of the cell during the alarm)
id
door microswitch input alarm (the maximum tempera-
ture of the cell during the alarm); see also parameter i4
PF
power supply interruption alarm (cell temperature when
power is restored); see also parameters A10 and A12
Notes:
• the instrument stores the minimum and maximum tem-
perature alarm provided the temperature associated with
the alarm is that of the cell (parameter A0 = 0)
• to avoid repeatedly storing alarms due to interruptions
in the power supply, disconnect the power when the
instrument is switched off
• if the duration of the power supply interruption alarm is
long enough to cause a clock error (code “rtc”), the instru-
ment will not provide any information about the alarm
duration
• if the instrument is switched off no alarms will be stored
When the problem that caused the alarm disappears, the display is
restored to normal operation, with the exception of the power supply
interruption alarm (code “PF”) which requires manual restoration of
the normal display.
