Advanced configuration

The parameters are grouped into 6 sections depending on their function. To access it, press the

Temperature values are expressed in ºC. (Equivalent temperature in ºF)

If the access code is activated, a 2 digit code is requested, if the code entered is incorrect the unit will not enter programming mode.

After 20 seconds with no key being pressed, the equipment will return to the previous level. If you are on level 3, the changes will not be saved.

REGULATION AND CONTROL

Description

Temperature Adjustment (Set Point)

Calibrating probe 1 (Offset)

Probe 1 differential (Histeresis)

Upper blocking of the set point

(cannot be set above this value)

Lower blocking of the set point

(cannot be set below this value)

Type of delay for protection of the compressor

0=OFF/ON (since the last disconnection);

1=OFF-ON/ON-OFF (since the last shut-down /start-up)

Protection delay time

(value of the option selected in parameter C4)

Status of COOL relay with probe fault

0=OFF; 1=ON; 2=Average based on last 24 hours prior to probe fault;

3=ON-OFF as prog. C7 and C8

Time relay ON in case of faulty probe

(If C7=0 and C8¹0, the relay will always be OFF deenergised)

Time relay OFF in case of fault of probe 1

(If C8=0 y C7¹0, the relay will always be ON energised)

Idle time of the digital input for the change Set Point function to be

C11

activated (Only if P10 or P11 =1) (0=OFF)

Variation of the set point (SP) when the change set point function

C12

is active. (SP+C12 £ C2) (0= disabled)

Exit to Level 1

DEFROST CONTROL

Description

Defrost frequency (Time between two starts)

dEF

Maximum defrost duration (0=defrost deactivated)

Type of message during defrost:

0=Current temperature; 1=Temperature at start of defrost;

2=Display dEF message

Maximum duration of message

(Time added at the end of the defrost process)

Defrost end temperature (probe 2) (If P4 ¹ 1)

Defrost on equipment start-up

0=NO, First defrost as per d0

1=YES, First defrost as per d6

Defrost start delay on equipment start-up

Calculated time between defrost period :

0=Total actual time; 1 =Sum of times the compressor is on

Drip time at end of defrost

(compressor and fans off) (if P4 ¹ 1)

Exit to Level 1

FAN CONTROL

Description

F0 Fan shut-down temperature as per probe 2 (if P4 ¹ 1)

FAn

F1 Probe 2 differential (If P4 ¹ 1)

F2 Stop fans when stopping compressor 0=No, 1=Yes

F3 Fan status during defrost: 0=Parados; 1=En marcha

Starting delay after defrost (if F3=0)

Will only operate if it is higher than d9
