Entering to Programming Mode

When both and button is pressed, expression is shown on the display. After 5 secs pressing both buttons, programming mode accessing password is shown on the display. After entering the programming mode accessing password, paramters can be accesing

Press button for showing parameter value and saving the parameter value, press button for exit from parameter section without saving parameter value.

Set Value Changing Mode

It can be accessed with or button that is on front panel. When whichever or button is pressed expression is shown on the display, after releasing the pressed button set value is shown on the display and SV led becomes active. Set value can be adjusted with and buttons. Press button for exit from set value changing mode with saving set value or press button for exit from set value changing mode without saving set value

Front Panel

Hysteresis Parameter for Compressor Output (Default : 4 )

Hysteresis value for compressor output is determined with this parameter. It °C °C

°C

can be adjusted from 1 to 10

Evaporator Sensor Selection Parameter (Default : 1)

= Evaporator sensor is = Evaporator sensor is

passive active

Compressor Working Period In Case of Cabinet Probe Defect Parameter

Compressor working period in case of cabinet probe defect is determined with this parameter. It

(Default : 10 minutes)

can be adjusted from 1 to 240 minutes

Compressor Working Percentage In Case of Cabinet Probe Defect Parameter

Compressor working percentage in case of cabinet probe defect is determined with this parameter. It

(Default : %70)

can be adjusted from 0 to 100

Defrost Repeat Cycle Parameter

Defrost repeat cycle is determine with this parameter. When pressed the button for starting the device, this time is starts It can be adjusted from 1 to 99 hours.

(Default : 2 hours)

Defrost Stopping Temperature Parameter (Default : 2°C)

For evaporator sensor selection parameter = 0 (evaporator sensor is active) While the defrost operation is in progress, when the temperature value that is read from the evaporator sensor is higher than the this parameter value, then defrost operation is stoppped. It can be adjusted from minimum value to maximum value of device scale.

Defrost Time Parameter

Defrost time is determined with this parameter It can be adjusted from 0 to 99 minutes.

(Default : 30 minutes)

Fan Stopping Temperature Parameter (Default : 10°C)

when the temperature value that is read from the cabinet sensor is lower than the this parameter value, then fan is stopped. It can be adjusted from minimum value to maximum value of device scale.

Hysteresis Parameter for Fan Output

Hysteresis value for fan output is determined with this parameter. It °C °C

(Default : 2°C)

can be adjusted from 1 to 15

Fan Delay Time After Completion of Defrost Time Parameter (Default : 2 minutes)

It can be adjusted from 0 to 15 minutes.

Programming Mode Accessing Password

It is used for accessing to programming mode. It can be adjusted from 0 to 999. If it is 0, password is not entered for accessing to the parameters.
