Variables

Meaning

dFd

Display viewing during Defrost

Modbus Network address

Bdr

Modbus baudrate

Prt

Modbus parity check

Ald

Minimum and maximum temperature signalling and alarm display delay

Minimum time between shutdown and subsequent switching on of the compressor

CAL

Cold room sensor value correction

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.

CE2

Duration of compressor OFF time in the case of faulty ambient probe

(emergency mode).

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.

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.

Fst

FAN shutdown TEMPERATURE

The fans will stop if the temperature value read by the evaporator sensor is higher

than this value.

Fst differential

LSE

Minimum value attributable to setpoint.

HSE

Maximum value attributable to setpoint.

AU1

Auxiliary/alarm relay 1 control

AU2

Auxiliary/alarm relay 2 control

StA

Temperature setting for auxiliary relay

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.

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).
