Configuration - Danfoss AK-RC 204B Guia De Instalacion

Configuration

Condensed programming menu
Enables the rapid configuration of the most frequently-used parameters (SP, C1, d0, d1, d4, F3, A1 and A2). Press the SET key for 3
seconds to access it.
Extended programming menu
Use the extended programming menu to configure all of the unit's parameters in order to adapt it to installation requirements. Press the
SET key for 6 seconds to access it.
Important:
• If the function of the password has been configured as a keypad block (b10=2), or as an access block to parameters (b10=1), you
will be requested to enter the access code programmed in PAS when attempting to access either of the two functions. If the entered
password is not correct, the unit will go back to showing the temperature.
• Certain parameters or menus may not be visible depending on the configuration of the rest of the parameters.
Regulation and control
Level 1 Level 2 Description
SP Temperature setting (Set Point)
C0 Probe 1 calibration (Offset)
C1 Probe 1 differential (Hysteresis)
C2 Set Point top locking (it cannot be set above this value)
C3 Set Point bottom locking (it cannot be set below this value)
Type of delay for the protection of the compressor:
0=Minimum time of compressor in OFF
C4
1=Minimum time of compressor in OFF and in ON in each cycle
C5 Protection delay time (Value of the option selected in parameter C4)
COOL relay status with fault in probe 1:
0=OFF; 1=ON; 2=Average according to last 24 h prior to probe error
C6
3=ON-OFF according to prog. C7 and C8
Relay time in ON in the event of probe 1 failure
C7
(If C7=0 and C8≠0, the relay will always be disconnected in OFF)
Relay time in OFF in the event of probe 1 failure
C8
(If C8=0 and C7≠0, the relay will always be connected in ON)
rE
C9 Maximum duration of the continuous cycle mode. (0=deactivated)
Variation of the Set Point (SP) in continuous cycle mode. When it reaches
C10 this point (SP+C10), it reverts to the normal mode. (SP+C10 ≥ C3).
The value of this parameter is always negative, unless it is 0. (0=OFF)
Variation of the Set Point (SP) when the change Set Point function is active.
C12
(SP+C12 ≤ C2) (0= deactivated)
Maximum start time from Pump Down
C19
(Values between 1 and 9 seconds will not be accepted) (0=deactivated)
C20 Maximum time for pump down (0= deactivated)
Probe to be displayed: 0=All probes (sequential)
C21 1=Probe 1 (Cold Room), 2=Probe 2 (Evaporator), 3=Probe 3 (According to
I20)
C22 Stop fans and compressor on opening door 0=No, 1=Yes
C23 Start-up delay for fans and compressor with door open
C27 Probe 3 calibration (Offset)
