5 ENERGY SAVING

5.1 Preliminary notes

Once the time you have set with parameter i10 has passed,
without activations of the door micro switch input (after the
cell temperature has reached the work set-point) the “en­ergy saving” function is activated (until the input is activated
again).
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).
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 micro switch 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
condition 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 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 10.1.

8.1 Preliminary notes

The activation of defrosting causes the activation of
the digital input (at maximum for the time established
with parameter d24 or until the conclusion of
predripping).
If the digital input is connected in parallel to the digital input
of other devices configured in the same way, the activation
of the input caused the activation of defrosting in the other
devices.
The devices start dripping simultaneously with the con­clusion of the predripping of the last device to end the
same.
