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.

8 SYNCHRONISATION OF DEFROSTING

PERIODS (ONLY IF PARAMETER i0 AND/OR
PARAMETER i5 IS SET AT 6)

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.

Notes:

(1) the unit of measurement depends on P2
(2) Properly set the parameters corresponding to the

regulators after modifying parameter P2

(3) the value depends on parameter P2 (0.1 °C or 1

°F)

(4) the parameter has effect even after an interrup-

tion in the power supply that occurs while the
device is switched on

(5) the time established with the parameter is counted

even when the device is switched off

(6) if parameter C1 is set at 0, the delay after the end

of the cell probe error will be 2 min

(7) if parameter C2 is set at 0, the device will function

as if parameter C18 were set at 0
(8) The parameter differential is 2.0 °/4 °F
(9) if when the device is switched on, the condenser

temperature is already above that established in

parameter C7, then parameter C8 will not have

effect
(10) compressor 2 is switched off when compressor 1 is

switched off
(11) the device memorises the defrosting interval count

every 30 minutes; the modification of parameter

d0 has effect from the conclusion of the previous

defrosting interval (or the activation of defrosting

in manual mode)
(12) the display restores normal operation when, on

conclusion of evaporator fan standstill, the cell tem-

perature drops below that which has blocked the

display (or if a temperature alarm occurs)
(13) if parameter P3 is set at 0 or 2, the device will

function as if parameter d8 were set at 0
(14) if when defrosting is activated, the operating dura-

tion of the compressor is less than the time estab-

lished with parameter d5, the compressor will re-

main on for the amount of time necessary to com-

tablished with parameter F11 on condition that the
compressor is off

(26) if the parameter i0 and parameter i5 are set at the

same value, the effect will be caused by the acti­vation of at least one of the inputs (until both
inputs are deactivated)

(27) the compressor is switched off 10 sec after the

activation of the input; if the input is activated
during defrosting or when the evaporator fan is
deactivated, the activation will not have any effect
on the compressor

(28) the device stores the alarm once the time estab-

lished in parameter i2 has expired; if parameter i2
is set at -1, the device will not store the alarm

(29) make sure that the time established with param-

eter i7 is less than that established with parameter
i9

(30) to avoid damaging the unit connected to the

instrument, change the parameter setting when
the device is switched off

(31) if parameter u2 is set at 0, switching off the device

may cause the cell light and/or the auxiliary output
to switch off (the next time the instrument is
switched on the unit connected will remain switched
off); if parameter u2 is set at 1, switching off the
device will not cause the cell light or the auxiliary
output to switch off (the next time the instrument
is switched on the unit connected will remain
switched on).

(32) the resistors are switched on when the tempera-

ture of the cell drops below the “work set-point +
u7” and are switched off when the temperature
rises above the “work set-point + u7 + 2 °C/°F”.

(15) if parameter P3 is set at 0, the device will function

as if parameter A0 were set at 0 but it will not store

the alarm
(16) during defrosting and dripping and when the evapo-

rator fan is stopped, the temperature alarms are

absent, provided that these were signalled after

the activation of defrosting
(17) during activation of the door micro switch input,

the maximum temperature alarm is absent,

provided the alarm was signalled after the activation

of the input
(18) parameters F13 and F14 have effect when the

compressor is off
(19) parameters F13 and F14 have effect when the

compressor is on
(20) if parameter P3 is set at 0, the device will function

as if parameter F0 were set at 2
(21) parameters F13 and F14 have effect when the

evaporator temperature is below the temperature

established with parameter F1
(22) parameters F13 and F14 have effect when the

compressor is on and the temperature of the

evaporator is below the temperature established

with parameter F1
(23) the parameter can also be modified using the

procedure described in paragraph 4.2
(24) if parameter P4 is set at 0, the condenser fan will

function in parallel with the compressor
(25) the condenser fan is off when the temperature of
