5 WARNING LIGHTS AND DIRECTIONS

5.1 Signals

LED Meaning

Compressor LED

If the LED is on, the compressor is on

If the LED is flashing:

- the working setpoint is in the process of being

set (via the procedure described in paragraph

4.1)

- a compressor protection will be in progress

Defrost LED

If the LED is on, defrost is in progress

If the LED is flashing, dripping will be in progress

Energy saving LED

If the LED is on and the display is switched on, the

“energy saving” function is in progress

If the LED is on and the display is switched off, the

"low consumption" function is in progress; press a

key to restore normal display

°C Celsius degrees LED

If the LED is on, the unit of measurement for tem-

perature is Celsius degrees

°F Fahrenheit degrees LED

If the LED is on, the unit of measurement for tem-

perature is Fahrenheit degrees

LED on/stand-by

If the LED is on, the device is switched off

5.2 Signals

Code Meaning

Loc the keyboard is blocked; see paragraph 3.6

- - - the operation requested is not available

6 ALARMS

6.1 Alarms

Code Meaning

AL Minimum temperature alarm

Solutions:

- check the room temperature; see A1 parameter

Main consequences:

- the device will continue to operate normally

AH Maximum temperature alarm

Solutions:

- check the room temperature; see A4 parameter

Main consequences:

- the device will continue to operate normally

id Door switch input alarm

Solutions:

- check the causes of the activation of the input;

see i0 and i1 parameters

Main consequences:

- the effect established with the i0 parameter

iA Multifunction input alarm or pressure switch alarm

Solutions:

- check the causes of the activation of the input;

see i0 and i1 parameters

Main consequences:

- the effect established with the i0 parameter

COH Condenser overheated alarm

Solutions:

- check the condenser temperature; see C6 pa-

rameter

Main consequences:

- the device will continue to operate normally

CSd Compressor shut down alarm

Solutions:

- check the condenser temperature; see C7 pa-

rameter

- switch the device off and back on again: if

when the device is switched back on, the tem-

perature of the condenser is still higher than

that established in C7 parameter, disconnect

the power supply and clean the condenser

Main consequences:

- the compressor will be switched off

dFd Defrost alarm switched off because maximum time

has been reached

Solutions:

- check the integrity of the evaporator probe; see

d2, d3 and d11 parameters

- press a key to restore normal display

Main consequences:

- the device will continue to operate normally

When the cause of the alarm disappears, the device restores

normal operation, except for the following alarms:

- compressor shut down alarm (code “CSd”) which re-

quires the switching off of the device or the temporary

suspension of the power supply

- defrost alarm switched off because maximum time has

been reached (code “dFd”) which requires the pressing

of a key.

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 over-

heated alarm (code “COH”) will never be acti-

vated

- if P4 parameter is set at 2, the compressor shut

down alarm (code “CSd”) will never be acti-

vated

When the cause of the error disappears, the device restores

normal operation.

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

If the POF parameter is set to 0:

1. Connect/disconnect the device power supply.

If the POF parameter is set to 1:

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.

3.4 Temperature display as detected by the probes

1. Make sure that the keyboard is not locked and that no

procedure is in progress.

2. Hold the key for 4 s: the display will show the

first label available.

3. Press and release the or key to select a

label.

4. Press and release the key.

The following table shows the correspondence between the

labels and the temperature displayed.

Label Displayed temperature

Pb1 room temperature

Pb2 if the P4 parameter is set to 1, evaporator tempera-

ture

if the P4 parameter is set to 2, condenser tempera-

ture

To exit the procedure:

5. Press and release the key or do not operate for

60 s.

6. Press and release the key.

If the second input functions as digital input (that is to say, if

the P4 parameter is set to 0), the “Pb2” label shall not be

displayed.

3.5 Defrost manual activation

1. Make sure that the keyboard is not locked and that no

procedure is in progress.

2. Keep the key pressed for 4 s.

If the second input functions as evaporator probe (that is to

say, if the P4 parameter is set to 1) and when the defrost

starts the evaporator temperature exceeds the value set with

the d2 parameter, the defrost shall not be activated.

3.6 Keyboard locking/unlocking

To lock the keyboard proceed as follows:

1. Make sure no procedure is in progress.

2. Do not operate for 30 s: the display will show the mes-

sage “Loc” for 1 s and the keybord shall lock automati-

cally.
