Min. 0 min
Max. 15 min
Default 0 min

Compressor Door Open Delay/Cdd 

This parameter sets the delay in minutes before the compressor stops 
when the door is opened. If set to zero, the function is disabled.

"

Srt

Min. 0 min
Max. 60 min
Default 0 min

System resume after door open

Fan and Compressor resume after cut out by door open.

Power ON Delay

This is the delay in seconds between power-on and the compressor being 
activated.

 

Depends on the power ON temperature setting as explained below. 

"

Pot

"

Min. -100.0°C
Max. 200.0°C
Default -100.0°C

Power ON Temperature

This parameter is used to accelerate the first application test on the 
OEM assembly line; if the cabinet temperature is higher than this 
parameter the power ON Delay is overruled and the outputs are activated 
without delay.

Con

Condenser Protection settings

NOTE: A condensor temperature sensor is required to use these parameters.
Condenser protection is generally used in dusty environments where 
the condenser may accumulate a layer of dust or dirt and therefore be 
at risk of overheating.

"

CAL

"

Min. 0°C
Max. 200°C
Default 80°C

Condenser Alarm Limit/CAL

This parameter sets the temperature for the condenser at which an alarm 
will be generated.

"

CbL

"

Min. 0°C
Max. 200°C
Default 85°C

Condenser Block Limit/CbL

This parameter sets the temperature which if reached will cause the 
compressor to switch OFF.

"

CoL

"

Min. 0°C
Max. 200°C
Default 60°C

Condenser OK Limit/CoL

This parameter sets the temperature at which the compressor is 
allowed to start again after the temperature set in "

CbL

" above has been 

exceeded and the compressor stopped.

"

CLL

"

Min. -100°C
Max. 20°C
Default -5°C

Condenser Low Limit/CLL

This parameter sets the lowest (condenser) temperature at which the 
compressor is allowed to start.

diS

Display settings

NOTE: some display parameters can be set in such as way that they 
may be illegal in some jurisdictions. Please check local legislation.

Max. 10
Default 10

Display Intensity

The controller can have its display intensity (brightness) set in one of 
two ways:
A) With a Danfoss ambient light sensor attached, the brightness of the 

display is adjusted automatically according to the ambient light level 
(see the assignments section).

B) When no ambient light sensor is attached, the display intensity can 

be set to a fixed intensity. 
Both options are on a scale of 1 to 10, where 10 is the brightest.
