CE1

Duration of compressor ON time in the case of 

faulty ambient probe

(emergency mode). 

If CE1=0 the emergency mode in the presence of 

error E0 remains disabled, the compressor remains 

off and defrosting is prevented in order to conserve 

the remaining cold.

0 – 240 min

0 = disabled

0 min

CE2

Duration of compressor OFF time in the case of 

faulty ambient probe 

(emergency mode).

5 – 240 min

5 min

doC

Compressor safety time for door switch:

when the door is opened the evaporator fans shut 

down and the compressor will continue working for 

time 

doC

, after which it will shut down.

0 – 5 min

0 min

tdo

Compressor restart time after door opening. 

when 

the door is opened and after tdo time, it’s setted back 

the normal functioning giving door open alarm (Ed)

If the door switch is closed and the light stays on for 

a longer time than tdo light cell alarm is signaled 

(E9). With tdo=0 the parameter is disabled.

0 – 240 min

0 = disabled

0 min

Fst

FAN shutdown TEMPERATURE

The fans will stop if the temperature value read by 

the evaporator sensor is higher than this value.

-45 – 99 °C

99 °C

Fd

Fst differential

1 – 10 °C

2 °C

LSE

Minimum value attributable to setpoint.

-45 – (HSE-1) °C

-45 °C

HSE

Maximum value attributable to setpoint.

(LSE+1) – 99 °C

99 °C

AU1

Auxiliary/alarm relay 1 control

-6 (NC) = relay de-energised 

during stand-by

-5 (NC) = Contact for casing 

element control (AUX 

relay closed with 

compressor output 

inactive).

-4 (NC) = pump down function 

(NC, see CHAP 5.16)

-3 (NC) = automatic auxiliary 

relay managed by StA 

temp. setting with 2°C 

differential (NC)

-2 (NC) = manual auxiliary relay 

controlled via AUX key 

(NC)

-1 (NC) = alarm relay (NC)

 0 = relay deactivated

 1 (NO) = alarm relay (NO)

 2 (NO) =manual auxiliary relay 

controlled via AUX key 

(NO)

 3 (NO) = automatic auxiliary 

relay managed by StA 

temp. setting with 2°C 

differential (NO)

 4 (NO) = pump down function 

(NO, see CHAP 5.16)

 5 (NO) = free voltage contact for 

condensing unit (AUX 

relay and compressor 

relay in parallel)

 6 (NO) = relay excited during 

stand-by

-1

AU2

Auxiliary/alarm relay 2 control

(like AU1 )

5

StA

Temperature setting for auxiliary relay

-45 – 99 °C

0 °C

nSC

Correction factor for the SET button during night 

operation 

(energy saving)

(with In1 or In2 = 8 or -8) 

During night operation the control set is: 

Set Control = Set + nSC 

In night mode decimal point flashes.

-20 – 20 °C

0 °C
