Variables

Meaning

In1

INP-1 input setting

In2

INP-2 input setting

bEE

Buzzer enable

mOd

Thermostat functioning mode

Password type of protection

(active when PA is not equal 0)

Password

(see P1 for the type of protection)

reL

Release software

Troubleshooting

Alarm code Possible cause

Cold room temperature sensor not working properly

Defrost sensor not working properly (in this case defrosts will last time d3)

Eeprom alarm

An EEPROM memory alarm has been detected

(All outputs except the alarm one are deactivated)

Man in cold room alarm

Compressor protection tripped

(e.g. thermal protection or max pressure switch)

(All outputs except the alarm one – where applicable – are deactivated)

Open door Alarm. When the door is opened and after tdo time, it's setted back the

normal functioning giving door open alarm (Ed)

Cell light alarm.

The light of the cell has been on for a time greater than tdo.

Maximum temperature alarm.

The temperature inside the cold room has exceeded the max. temperature alarm

setting (see variables A2, user programming level)

Minimum temperature alarm.

The temperature inside the cold room has exceeded the min. temperature alarm

setting (see variables A1, user programming level)

Value

8 = Night mode digital input (energy saving,

N.O.)

7 = Stop defrosting remotely (N.O.) (reads rising

edge of impulse)

6 = Start defrosting remotely (N.O.) (reads rising

edge of impulse)

5 = Stand-by remotely (N.O.) (In order to indicate

Stand-By mode, the display shows 'In5'

alternating with the current view)

4 = Pump-down pressure switch (N.O.)

3 = Man-in-room alarm (N.O.)

2 = Compressor protection (N.O.)

1 = Door switch (N.O.)

0 = disabled

-1 = Door switch (N.C.)

-2 = Compressor protection (N.C.)

-3 = Man-in-room alarm (N.C.)

-4 = Pump-down pressure switch (N.C.)

-5 = Stand-by remotely (N.C.) (In order to

indicate Stand-By mode, the display shows

'In5' alternating with the current view)

-6 = Start defrosting remotely (N.C.) (reads falling

edge of impulse)

-7 = Stop defrosting remotely (N.C.) (reads falling

edge of impulse)

-8 = Night mode digital input (energy saving,

N.C.)

( like In1 )

0 = disabled

1 = enabled

0 = Cold function

1 = Hot function

(in this mode defrosting and fan disable Fst

are excluded)

0 = only display set point

1 = display set point, AUX, light access

2 = access in programming not permitted

3 = access in second level programming not

permitted

0...999

0 = not active

indicates software version

Solution

• Check that cold room temperature sensor is working properly

• If the problem persists replace the sensor

• Check that defrost sensor is working properly

• If the problems persists replace the sensor

• Switch unit off and back on

• Reset the alarm input inside the cold room

• Check that compressor is working properly

• Check compressor absorption

• If the problem persists contact the technical assistance service

• Check door switch status

• Check door switch connections

• If the problem persists contact the technical assistance service

• Turn off the light

• Check that the compressor is working properly.

• Sensor not reading temperature properly or compressor start/stop

control not working.

• Check that the compressor is working properly.

• Sensor not reading temperature properly or compressor start/stop

control not working.
