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

2. Make sure that the keyboard is not locked and that no
procedure is in progress.
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
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 2, the condenser overheated alarm (code “COH”) will never be activated
- if P4 parameter is set at 2, the compressor shut
down alarm (code “CSd”) will never be activated
When the cause of the error disappears, the device restores
normal operation.

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
(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 or 2, the device will function as if d8 parameter were set at 0
(11) during defrost and dripping, the maximum temperature alarm is absent, provided that it was triggered after defrost
activation.
(12) during activation of the door switch input, the maximum temperature alarm is absent, provided the alarm was
signaled after the activation of the input
(13) the compressor is switched off 10 s after the activation of the input.
