How to set the set point (desired temperature value)
Step Action Effect Meaning
1Press for 1 second
After 1 second the display will
show the current set point
This the currently active
control set point
2Press or
The value on the display will
increase or decrease Set the desired value
3Press
The controller will show the tem-
perat. read by the probes again
The set point is modi-
fied and saved
Another way of changing the set point is to set parameter“St” (see the tables below)
How to access and set parameters
type “F” (FREQUENT, not protected by password)
type “C” (CONFIGURATION, password protected)
Step Action Effect Meaning
1Press for 3 seconds
After 3s the display will
show the 1st parameter, “0”
(password)
Access to type “F” param. is
direct without password
2Press or
The value on the display will
increase or decrease.
Enter the password“22” to
access the type “C” param.
or whatever different value
for the type “F” parameters.
3Press
The display will show “St”
(Setpoint)
This is the current value of
the Setpoint
4Press or
If the password set is 22 the
display will scroll the list of type
“C” parameters (CONFIGURA-
TION) otherwise the list of type
“F” parameters (FREQUENT )
Set the desired value
5Press
The display will show the
parameter name
This is the current value of
the parameter
6Press or
The value on the display will
increase or decrease Set the desired value
7Press
The display will show the
parameter name again
Important: parameters not
yet saved
8
Repeat steps 2, 3, 4 &
5 for all parameters
required
9Press for 5
seconds
The controller will display
the temperature read by the
probes again
Important: only now have
all the parameters been
updated
For both types of access (type “F” and type “C”) there is a timeout (no button on the keypad
pressed for 1 min), the procedure is ended without saving the parameter.
Accessing the parameters divided by functional blocks (allows the user to scroll
the list of parameters in blocks)
Once having accessed the type “F” or “C” parameters (see tables above)
Step Action Effect Meaning
1Press
The display will show the name
of the functional block that the
parameter belongs to
Example ‘CMP’ for the com-
pressor parameters,‘dEF’ for
the defrost parameters
2Press or
The display will show the name
of the other functional blocks
Example ‘Fan’ for the fan
parameters
3Press
The display will show the name
of the first parameter in the
functional block selected
Example “F0” for ‘Fan’
Alarms with manual reset:
the alarms with manual reset can be reset by pressing the and for more than 3 s.
Manual defrost:
as well as the automatic defrost function, a manual defrost can be enabled, if the tempera-
ture conditions allow, by pressing the button for more than 5 s.
HACCP function:
ir33+ is compliant with the HACCP standards in force since it allows the monitoring of the
temperature of the stored food.
“HA” alarm = exceeded maximum threshold: up to three HA events are saved (HA, HA1,
HA2) respectively from the more recent (HA) to the oldest (HA2) and a HAn signal that di-
splays the number of occurred HA events.
“HF” alarm = power failure lasting over a minute and exceeded AH maximum threshold:
up to three HF events are saved (HF, HF1, HF2) respectively from the more recent (HF) to the
oldest (HF2) and a HFn signal that displays the number of occurred HF events.
HA/HF alarm setting: AH parameter (high temp. threshold); Ad and Htd (Ad+Htd = HACCP
alarm activation delay).
Display of the details:
access to HA or HF parameters pressing the button and use or buttons to
glance over.
HACCP alarm erasing:
press the and buttons for more than 5 seconds, the message‘res’indicates that the
alarm have been deleted. To cancel the saved alarms press the + + buttons for
more than 5 seconds.
Continuous cycle:
Pressing the buttons and simultaneously for more than 3 s enables the continuous
cycle function. During operation in continuous cycle, the compressor continues to operate
for the time ‘cc’ and it stops when reaches the ‘cc’ time out or the minimum temperature
envisaged (AL = minimum temperature alarm threshold).
Continuous cycle setting: “cc” parameter (continuous cycle duration): “cc” = 0 never acti-
ve; “c6” parameter (bypassing the alarm after the continuous cycle): “cc” = 0 never active; it
avoids or delays the low temperature alarm after the continuous cycle.
Procedure for setting the default parameter values
To set the default parameter values on the controller, proceed as follows:
1: switch the instrument off;
2: switch the instrument back on, holding the button until the message “Std” is shown
on the display.
Note: the default values are only set for the visible parameters (C and F). For further details
see table “Summary of operating parameters”.
