5 ENERGY SAVING
5.1 Preliminary notes
Once the time you have set with parameter i10 has passed,
without activations of the door microswitch input (after the
cell temperature has reached the work set-point) the “en-
ergy saving” function is activated (until the input is activated
again).
During function “Energy Saving” the working set-point 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).
It is also possible to activate the “energy saving” function in
remote mode through the digital inputs (with effect only on
the compressor).
6 “HACCP” FUNCTION
6.1 Preliminary notes
The device can memorise the following HACCP alarms:
-
minimum temperature alarm (code “AL”)
- maximum temperature alarm (code “AH”)
- door microswitch input alarm (code “id”)
The device supplies the following information for every alarm:
-
the critical value
- the duration of the alarm (from 1 min to 99 hours and
59 min, partial if the alarm is in progress).
Code Critical value
AL the minimum temperature of the cell during any
alarm of this type
AH the maximum temperature of the cell during any
alarm of this type
id the maximum cell temperature during any alarm
of this type; see also parameter i4
The device stored the minimum temperature alarm on con-
dition that the temperature associated to the alarm is that of
the cell (parameter A0 = 0).
if the device is switched off, no alarms will be stored.
The device updates the information regarding the alarms
provided the critical value of the new alarm is more critical
than that stored or provided the information has already
been displayed.
The “HACCP” LED provides information regarding the storage
status of the alarms; see paragraph 9.1.
6.2
Display of HACCP alarm information
To begin the procedure:
1.
Make sure that the keyboard is not locked and that no

6.
Press and release the key: the HACCP LED will
stop flashing and remain on permanently and the dis-
play will show, for example, the following information
in succession (for example):
Inform. Part
