HUMIDITY PERCENTAGE (ONLY IF PARAMETER
F0 IS ISET AT 5)
4.1
Preliminary notes
During operation for low percentage of relative humidity, the
evaporator ventilator will be switched on if the compressor is
switched off (parameter F4 determines the amount of time
it is switched off while parameter F5 determines the amount
of time it is switched on).
During operation for a high percentage of relative humidity
the evaporator fan is always on.

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 “en-
ergy 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.
