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 1 or 2 and F0 param-

eter 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 over-

heated alarm (code «COH») will never be acti-

vated

—

if P4 parameter is set at 3, the compressor shut

down alarm (code «CSd») will never be acti-

vated

When the cause of the error disappears, the device restores

normal operation.

or

key within 15

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

—

touch 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 touching

of a key.

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 1 or 2 and F0 param-

eter 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 over-

heated alarm (code «COH») will never be acti-

vated

—

if P4 parameter is set at 3, the compressor shut

down alarm (code «CSd») will never be acti-

vated

When the cause of the error disappears, the device restores

normal operation.
