The Buttons; Set Menu; Set Temperature; Reading The Temperature At Defrost Sensor - Danfoss EKC 302D Instructions Manual

Access code 1 (all settings)
Used sensor type (Pt /PTC/NTC)
Only EKC 302D: Readout of software version
Display step = 0.5 (normal 0.1 at Pt sensor)
Max hold time after coordinated defrost
Select signal for display view. S4% (100%=S4, 0%=S3)
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-signal). 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 signal). 11=forced cooling.
12=coordinated defrost. 13=case shut down (302D).
Configuration of light function (relay 4)
1=ON during day operation. 2=ON / OFF via data com-
munication. 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 2

**) 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 upper and lower button depressed at the same time as you recon nect the supply voltage
