3 USER INTERFACE

3.1 Preliminary notes

Operating statuses:

- “on” status (the device is powered and is on; utilities
may be on

- stand-by” status (the device is powered but is switched
off via software; utilities are off

- the “off” status: the device is not powered; utilities are
off.

Hereafter, if the POF parameter is set to 0, with the word
“switch-on” means the passage from “off” status to “on”
status; the word “switch-off” means the passage from “on”
status to “off” status.
If the POF parameter is set to 1, with the word “switch-on”
means the passage from “stand-by” status to “on” status; the
word “switch-off” means the passage from “on” status to
“stand-by” status.
When the power is switched back on, the device displays the
status that it was in at the time it was disconnected.

3.2 Device switch-on/off

3. Hold the key for 4 s: the LED will flash, after
which it will turn off/on.

3.3 The display

If the device is switched on, during normal operation, the
display will show the magnitude established with P5, except
during defrost, when the device will show the temperature
established with d6 parameter.
If the device is switched off, the display will be switched off;
the LED shall be on.
If the device is in "low consumption" mode, the display will be
switched off and the LED shall be on.

7 ERRORS

7.1 Errors

Code Meaning

Pr1 Room temperature probe error

Solutions:

- check that the probe is the PTC or NTC type;
see P0 parameter

- check the device-probe connection

- check room temperature

Main consequences:

- compressor activity will depend on C4 and C5
parameters

- the defrost will not be activated

- the alarm output will be switched on

Pr2 Evaporator probe or condenser probe error

Solutions:

- the same as in the previous example, but with
regard to the evaporator probe or the condenser
probe

Main consequences:

- if P4 parameter is set at 1, the defrost interval
will last for the amount of time set with d3
parameter

- if P4 parameter is set at 1 and d8 parameter is
set at 2 or to 3, the device will operate as if d8
parameter were set at 0

- if P4 parameter is set at 1 or 2 and F0 param­eter is set at 3 to 4, the device will operate as if
parameter were set at 2

- if P4 parameter is set at 3, the condenser over­heated alarm (code “COH”) will never be acti­vated

- if P4 parameter is set at 3, the compressor shut
down alarm (code “CSd”) will never be acti­vated

- the alarm output will be switched on

When the cause of the error disappears, the device restores
normal operation.

the compressor, until the input is deactivated); see also r4

(code “iA”) - the device will continue to operate normally; see also
i2

ALARM (code “iA”) - the compressor will be switched off (until the
input is deactivated); see also i2

0 = normally open (active input with closed contact)
1 = normally closed (active input with open contact)

i2 -1 120 min 30 if i0 = 1 or 2, delay in signalling of door switch input alarm (code “id”)

-1 = the alarm will not be signalled
if i0 = 4, delay in signalling of multifunction input alarm (code “iA”)

-1 = the alarm will not be signalled
if i0 = 5, delay in switching off of compressor after the activation of the
maximum pressure switch alarm (code “iA”)

-1 = reserved

i3 -1 120 min 15 maximum duration of the effect caused by the activation of the door switch

input alarm (code “id”) on the compressor

-1 = the effect will last until the input is deactivated

i10 0 999 min 0 time that must pass in absence of door switch input activations (after the

room temperature has reached the working setpoint) for the “energy saving”
function to be activated; see also r4, F4, F5 and HE2
0 = the function will never be activated due to the effect of this condition

i13 0 240 - - - 180 number of door switch input activations such as to provoke the defrost

activation
0 = defrost will never be activated due to the effect of this condition

i14 0 240 min 32 minimum duration of the door switch input activation such as to provoke the

defrost activation
0 = defrost will never be activated due to the effect of this condition

PARAM. MIN. MAX. U.M. DEF. DIGITAL OUTPUTS (20)

HE2 0 999 min 0 maximum duration of the “energy saving” function activated due to the effect

of absence of door switch input activation; see also r4, F4, F5 and i10
0 = the function will last until the input is activated

HE3 0 240 min 2 time interval with no key strokes, after which the "low consumption" function

is activated

Notes:

(1) the unit of measurement depends on P2
(2) properly set the parameters corresponding to the regulators after setting P2 parameter
(3) if r5 parameter is set at 1, the “energy saving" function and the defrost management will be switched off; see also

F1 parameter
(4) the parameter has effect even after an interruption in the power supply that occurs while the device is switched on
(5) the time set by paramenter C2 is counted also when the device is off
(6) the differential of C8 parameter is 2.0°C/4°F
(7) if when the device is switched on, the condenser temperature is already above that established in C7 parameter,

then C8 parameter will not have effect
(8) the value ∆t depends on r12 parameter (r0 if r12 = 0, r0/2 if r12 = 1)
(9) the display restores normal operation when, at the end of the dripping phase, room temperature falls below the

value that locked the display (or if a temperature alarm is triggered)
(10) if P4 parameter is set at 0, 2 or 3, the device will function as if d8 parameter were set at 0
(11) if when defrost is activated, the operating duration of the compressor is less than the time established with d15

parameter, the compressor will remain on for the amount of time necessary to complete defrost, then the defrost

shall be activated
(12) during defrost, dripping and evaporator fan standstill, the maximum temperature alarm is absent, provided that it

was triggered after defrost activation.
(13) during activation of the door switch input, the maximum temperature alarm is absent, provided the alarm was

signalled after the activation of the input
(14) F4 and F5 parameters have effect when the compressor is off
(15) F4 and F5 parameters have effect when the compressor is on
(16) if P4 parameter is set at 2, the device will function as if F0 parameter were set at 2
(17) F4 and F5 parameters have effect when the evaporator temperature is below the temperature established with F1

parameter
(18) F4 and F5 parameters have effect when the compressor is on and the temperature of the evaporator is below the

temperature established with F1 parameter
(19) the compressor is switched off 10 s after the activation of the input; if the input is activated during defrost or when

the evaporator fan is deactivated, the activation will not have any effect on the compressor
