Input signal on DI2. Function:
(0=not used. 1=status on DI2. 2=door function with alarm when open. 3=door
alarm when open. 4=defrost start (pulse-pressure). 5=ext. main switch 6=night
operation 7=change reference (activate r40). 8=alarm function when closed.
9=alarm function when open. 10=case cleaning (pulse pressure). 11=forced cool-
ing.). 12=coordinated defrost)
Configuration of light function (relay 4)
1=ON during day operation. 2=ON / OFF via data communication. 3=ON follows
the DI-function, when DI is selected to door function or to door alarm
Activation of light relay (only if o38=2)
Rail heat On time during day operations
Rail heat On time during night operations
Rail heat period time (On time + Off time)
Case cleaning. 0=no case cleaning. 1=Fans only. 2=All output Off.
Selection of EL diagram. See overview page 6
Access code 2 (partly access)
Save the controllers present settings to the programming key. Select your own
number.
Load a set of settings from the programming key (previously saved via o65 func-
tion)
Replace the controllers factory settings with the present settings
Service
Status codes
Temperature measured with S5 sensor
Status on DI1 input. on/1=closed
Temperature measured with S3 sensor
Status on night operation (on or off ) 1=closed
Temperature measured with S4 sensor
Thermostat temperature
Read the present regulation reference
Status on DI2 output. on/1=closed
Temperature shown on display
Measured temperature for alarm thermostat
Status on relay for cooling
Status on relay for fan
Status on relay for defrost
Status on relay for railheat
Status on relay for alarm
Status on relay for light
*) Can only be set when regulation is stopped (r12=0)
**) Can be controlled manually, but only when r12=-1
***) With access code 2 the access to these menus will be limited
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you recon nect the supply voltage

Questions and answers
Is there a possibility with the EKC 202D2 to correct the temperature sensor reading offset,
Yes, the Danfoss EKC 202D can correct the temperature sensor reading offset. This is done using the parameters r09 and r10, which allow for the correction of the signal from sensors S4 and S3, respectively. Both parameters have a correction range of -10.0 K to 10.0 K.
