During the Overcooling function, the work set-point is decreased
from the temperature established by parameter r5; the function will
last for the time established by parameter r6.
Defrosting is never activated during the Overcooling function; if the
defrosting interval expires when the function is in progress, defrosting
will be activated on conclusion of the function.
4.7
Activation of defrosting in manual mode
• make sure that the keyboard is not locked, that no procedure is in
progress and the Overcooling function is not in progress
• hold the key down for 4 s.
If the function of the evaporator probe is that of defrosting probe
(parameter P3 = 1) and on activation of defrosting the temperature of
the evaporator is above that established with parameter d2, defrosting
will not be activated.
4.8
Functioning due to low or high relative humidity
percentage (only if parameter F0 is set at 5)
During functioning due to low relative humidity percentage, the
evaporator fan will be switched-on if the compressor is on and is
switched-on cyclically if the compressor is off (parameter F4 establishes
the duration of evaporator fan switch-off and parameter F5 that
regarding switch-on).
During functioning due to the high relative humidity percentage, the
evaporator fan is always on.
4.8.1
Activation of the functioning due to low or high
relative humidity percentage (only if parameter
F0 is set at 5)
• make sure that the keyboard is not locked and that no procedure is
in progress
• press and hold the and key for 4 s: the display will show “rhL”
(functioning due to low relative humidity percentage) or “rhH”
(functioning due to high relative humidity percentage) for 10 s.
To restore normal display in advance:
• press a key.
It is also possible to activate functioning due to low or high relative
humidity percentage using parameter F6.
If parameter F0 is not set at 5, pressing the and key will cause the
“- - - -“ indication to be displayed for 1 s.
4.8.2
Learning of the type of functioning in progress
(due to low or high relative humidity percentage
only if parameter F0 is set at 5)
• make sure no procedure is in progress
• press and release the key and the key: the display will show
“rhL” (functioning due to low relative humidity percentage) or “rhH”
(functioning due to high relative humidity percentage) for 10 s.
To restore normal display in advance:
• press a key.
If parameter F0 is not set at 5, pressing the and key will cause:
• the display of the “- - - -“ indication for 1 s if the keyboard is not locked
• the display of the “Loc” label for 1 s if the keyboard is locked.
4.9
Switch-on/off of the cabinet light in manual mode
(only if parameter u1 and/or parameter u11 is set
at 0)
• make sure no procedure is in progress
• press and release the key: the light LED will switch-on/off.
Using the door micro switch input, the cabinet light can also be
switched-on/off in remote mode; 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 key down
for 2 s will cause the switch-on/off of the multipurpose LED and of the
auxiliary output.
4.10
Switch-on of the demisting heaters (only if
parameter u1 and/or parameter u11 is set at 1)
• make sure that the instrument is on and that no procedure is in
progress
• hold the key down for 2 s: the multipurpose LED will switch-on
and the heaters will be switched on, both for the time established
with parameter u6.
The demisting heaters cannot be switched off in manual mode (i.e.
before the time established with parameter u6 has passed).
4.11
Switch-on/off of the auxiliary output in manual
mode (only if parameter u1 and/or parameter u11
is set at 2)
• make sure that the keyboard is not locked and that no procedure is
in progress
• press and release the key.
The multipurpose input can also be used to switch the auxiliary output
on/off in remote mode.
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 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 in manual mode, sit can
only be switched off in the same way (also, if the auxiliary output has
been switched off in remote mode, it can only be switched off in the
same way); see also parameter u2.
4.12
Energy Saving
During the Energy Saving function, the work set-point is increased of
the temperature established with parameter r4 and the evaporator fan
is switched on cyclically, on condition that the parameter F0 is set at 1
or 2 (parameter F13 establishes the duration of fan switch-off and
parameter F14 that regarding switch-on).
When the time established with parameter i10 has passed without
activation of the door micro switch (after the cabinet temperature has
reached the work set-point) the Energy Saving function is activated
automatically (until the input is activated again).
4.12.1
Activation/deactivation of the Energy Saving
function with effect only on the compressor
The multipurpose input can also be used to switch the Energy Saving
function on/off in remote mode.
The Energy Saving function can also be activated in real time at the
time established using parameter HE1. In this case, the function will
last for the time established with parameter HE2.

HACCP FUNCTION
6.1 Preliminary considerations
The instrument can memorise up to 9 HACCP alarms, after which the
most recent alarm will overwrite the oldest.
The instrument supplies the following information:
• the critical value
• the date and time of the alarm
• the duration of the alarm (from 1 min to 99 h and 59 min, partial if
the alarm is in progress).
CODE TYPE OF ALARM (CRITICAL VALUE)
AL minimum temperature alarm (the minimum cabinet
temperature during the alarm)
AH maximum temperature alarm (the maximum cabinet
temperature during the alarm)
id door micro switch input alarm (the maximum temperature
of the cabinet during the alarm); see also parameter i4
PF power supply cut-off alarm (the cabinet temperature on
power supply restore); see also parameters A10 and A12
Recommendations:
• the instrument memorises the minimum temperature alarm
and the maximum temperature alarm on condition that
the temperature associated to the alarm is that of the
cabinet (parameter A0 = 0)
• to prevent the power supply cut-off alarms being memorised
repeatedly, disconnect the power supply when the
instrument is off
• if the duration of the power supply cut-off alarm is such
to cause the clock error (“rtc” code), the instrument will
not supply any information regarding the duration of
the alarm
• if the instrument is off, no alarm will be memorised.
When the cause of the alarm disappears, the display restores normal
functioning, except for the power supply cut-off alarm (“PF” code)
that requires restore of normal display in manual mode.
to restore normal display in manual mode:
• press a key.
If parameter u1 and/or parameter u11 is set at 3, pressing the key will
also cause the alarm output to be deactivated.
The HACCP LED supplies information regarding the status of the HACCP
alarms memory; see paragraph 8.1.
6.2
Display of the information regarding the HACCP
alarms
To access the procedure:
• make sure that the keyboard is not locked and that no procedure is
in progress
• hold the key down for 1 s: the display will show the first label
available
• press and release the key or the key to select “LS”
• press and release the key: the display will show the most recent
alarm code (i.e. one of the codes given in the table in paragraph 6.1
followed by “1”. The higher the number that follows the alarm code
the older the alarm).
To select an alarm:
• press and release the key or the key (for example to select
“AH3”)
