Display defrost probe
To display the value measured by the defrost probe:
•
press Set and UP together for 3 s;
•
the code of parameter d/1 is displayed fl ashing;
•
continue holding the buttons until the value measured by the defrost
probe is displayed;
•
release the buttons;
•
the standard display is shown again after 10 s.

Auxiliary/light output activation
Activation from the keypad: for automatic activation from scheduler see
the second example in paragraph 3.5. To activate the auxiliary (H1 = 2)
and/or light output (H1 = 3) from the keypad:
•
press AUX and/or if present;
•
the message AUX fl ashes on the display for 1 s:
•
press and hold until activating the output and the corresponding icon
on the display, which then shows the standard display.

Probe calibration
Parameters /c1 to /c4 are used are used to calibrate the fi rst, second, third
and fourth temperature probe respectively. Access the parameters and
then set the required values. When pressing Set, after having entered the
value, the display does not show the parameter, but rather immediately
shows the new value of the probe reading being calibrated. This means
the result of the setting can be checked immediately and any adjustments
made as a consequence. Finally, press Prg for 5 seconds to save the value
of the parameter.

Minimum and maximum temperature monitoring
The controller can record the minimum and maximum temperature
measured by the control probe over a period of up to 999 hours (more
than 41 days).
To enable monitoring:
•
enter programming mode as explained in the corresponding
paragraph;
•
set r5=1;
•
select rt;
press: ir33+ ir33+ wide Easy wide
DEF
This displays how long minimum and maximum temperature monitoring
has been active, (if recording has just been enabled, rt=0);;
•
to restart temperature recording, press for more than 5 s:

The message "rES" indicates that the log has been deleted. The controller
resets the total hours and restarts monitoring;
•
press Set to return to the list of parameters;
•
to display the maximum temperature measured by the probe, read the
value associated with parameter rH;
•
to display the minimum temperature measured by the probe, read the
value associated with parameter rL.
Note: after the maximum time of 999 hours, minimum and
maximum temperature monitoring continues, while the time interval
remains fi xed at 999.
Important: the values of parameters rt, rL and rH are saved to the
controller's memory every hour. If the controller is not connected to an
uninterruptible power supply, a temporary blackout may mean the
values of rt, rL and rH measured in the last hour will be lost. When power
returns, the controller automatically restarts monitoring from the
previously saved values.
