I program a Danfoss EKC202A temperature controller and I show you how I do it.
Thermostat
Thermostat differential r01
Maximum limit when adjusting the cut-off temperature r02
Minimum limit when setting the cut-off temperature r03
Temperature correction on display r04
Temperature units (° C / ° F) r05
Saire r09 probe calibration
Internal start / stop: -1: manual mode, 0: EKC stopped, 1: running r12
Temp offset cutting overnight r13
Activate the cut-off temperature increase r39
Cut-off temperature increase (degrees) (triggered by r39 or DI) r40
Alarm
Temperature alarm delay (standard) A03
Door alarm delay A04
Temperature alarm delay (after defrost) A12
High temperature alarm limit A13
Low temperature alarm limit A14
Alarm delay associated with DI A27
High condenser temperature alarm limit (with S5 and o70 = 2) A37
Compressor
Minimum compressor running time (minutes) c01
Minimum time between two consecutive starts (minutes) c02
Invert the operation of output DO1 (compressor) c30
Defrost
Defrost type d01
End of defrost temperature d02
Time interval between defrosts d03
Maximum defrost duration d04
Displacement of the 1st defrost after energizing the d05
Drip time d06
Fan delay after defrost d07
Fan start temperature d08
Fan running during defrost (no / yes)
0: stopped
1: Running throughout the phase
2: Running during single warm-up phase
d09
End defrost probe (0 = no (time), 1 = S5, 2 = Saire) d10
Defrost on demand: accumulated cooling time (0 = Function canceled) d18
Defrost on demand: variation allowed to S5 (20 = Function canceled) d19
Fans
Stop fan when stopping compressor (yes / no) F01 no yes no
Fan stop delay F02
Fan stop temperature (measured with S5) F04
Real time clock
Up to six hours (hh) of defrost start.
0 = OFF
t01-t06 0 hours 23 hours 0 hours
The minutes (mm) of each of the 6 hours.
0 = OFF
t11-t16 0 min 59 min 0 min
Clock setting - time t07 0 hours 23 hours 0 hours
Clock setting - minutes t08 0 min 59 min 0 min
Clock setting - day t45
Setting the clock - month t46
Setting the clock - year t47
Various
Output activation delay after power failure o01
Function of digital input DI1:
0 = not used. 1 = communicates the status of DI1. 2 = door open and alarm. 3 = door alarm only. 4 = start a defrost (pulse signal). 5 = main switch.
6 = night operation 7 = cut-off temperature shift (activation r40).
8 = alarm when closing the contact. 9 = alarm when opening the contact. 10 = cabinet cleaning
(pulse signal). 11 = Inject when opening contact.
o02 0 11 0
EKC address o03
Send EKC address to gateway o04
Code 1 for access to all parameters (0 = code disabled) o05
Type of probes used (Pt / PTC / NTC) o06 Pt ntc Pt
Display value precision: yes = 0.5, no = 0.1 o15 no yes no
Maximum waiting time after a coordinated defrost (only via gateway) o16
Light function (relay 4; see parameter o72)
1 = ON during day operation. 2 = ON / OFF via communication bus. 3 = ON at the same time as
the DI when that DI is for the door or door alarm function.
o38 1 3 1
Activation of the light relay via communication bus (only if o38 = 2) o39
Cleaning the furniture. 0 = not active. 1 = Fan only ON. 2 = All outputs OFF. o46
Access code 2 to part of the parameters (0 = disable code) o64
Save the programming of an EKC in a "copy-key". o65
Dump the programming from a "copy-key" to an EKC o66
Replace "factory settings" with programming current o67
