Configuration
r12
r12 Main switch
Start / stop of refrigeration
With this setting refrigeration can be started, stopped or a manual override of the outputs can be allowed.
Start / stop of refrigeration can also be accomplished with the external switch function connected to a DI input.
Stopped refrigeration will give a ”Standby alarm”.
• (1)
ON
: Start
• (0)
OFF
: Stop
• (-1)
SEr
: Manual control of outputs allowed
o61
(1)
o61 Appl. Mode
Selection of application
The controller can be defined in various ways. Here you set which of the 4 applications is required.
Please refer to
for the controller in question.
o06
o06 SensorConfig
Sensor type selection
This parameter is for defining type of temperature sensors connected to the controller. All the mounted sensors (Sair, S5 and
Sc) must be of same type.
• (0)
n5
= NTC 5k (Danfoss type EKS211)
• (1)
n10
= NTC 10k (Danfoss type EKS 221)
• (2)
Pt
= Pt1000 (Danfoss type AKS11, AKS12, AKS21)
• (3)
Ptc
= PTC 1000 (Danfoss type EKS 111)
o02
o02 DI1 Config.
DI1 configuration
Here you can configure the DI1 to one of the functions listed below.
• (0)
oFF
= not used
• (1)
Sdc
= status display output
• (2)
doo
= door function. When the door is opened the compressor and fan are stopped after “C04 Compressor door open
delay”. If the door alarm delay expires an alarm is generated and cooling is resumed.
• (3)
doA
= door alarm. When the door is opened the compressor and fan are stopped after “C04 Compressor door open
delay”. If the door alarm delay expires an alarm is generated (cooling is not resumed).
• (4)
SCH
= main switch. Regulation is carried out when the input is short-circuited, and regulation is stopped when the input
is put in position OFF.
• (5)
nig
= day/night mode. When the input is short-circuited, there will be regulation for night operation.
• (6)
rFd
= reference displacement. Value in “r40” is added to the reference “r00” when the input is short-circuited
• (7)
EAL
= external alarm. Alarm will be given when the input is short-circuited.
• (8)
dEF
= defrost. Defrost is initiated when the input is short-circuited. Edge triggering is used. Defrost exit can take place by
time, temperature or by manually pressing defrost push button on the front panel.
• (9)
Pud
= pull down. Pull down is initiated when the input is short-circuited. Edge triggering is used. It will come out of pull
down based on time and temperature defined under parameter “r96” and “r97” or can be stopped manually by pressing
pull down push button on front panel.
• (10)
Sc
= condenser sensor
o37
o37 DI2 Config.
DI2 configuration
Here you can configure the DI2 to one of the functions listed below.
• (0)
oFF
= not used
• (1)
Sdc
= status display output
• (2)
doo
= door function. When the door is opened the compressor and fan are stopped after “C04 Compressor door open
delay”. If the door alarm delay expires an alarm is generated and cooling is resumed.
• (3)

= door alarm. When the door is opened the compressor and fan are stopped after “C04 Compressor door open
delay”. If the door alarm delay expires an alarm is generated (cooling is not resumed).

time, temperature or by manually pressing defrost push button on the front panel.
• (9)
Pud
= pull down. Pull down is initiated when the input is short-circuited. Edge triggering is used. It will come out of pull
down based on time and temperature defined under parameter “r96” and “r97” or can be stopped manually by pressing
pull down push button on front panel.

o62 Quick Setup
Transfer a set of presettings to the controller
It is possible to select a quick setting of a number of parameters. It depends on whether a cabinet or a room is to be controlled
and whether defrost is to be stopped based on time or based on temperature.
After the setting, the value will return to 0. Any subsequent adjustment/setting of parameters can be made, as required.
Please refer to
Quick setup – get a good start
.
o03
o03 Unit Addr
Network address for Modbus fieldbus
Data communication is possible through external EKA 206 to RS-485 adapter.
The network address must be set in the range between 1 – 120 to be integrated on a Modbus fieldbus.
Note:
Network address must be set to 0, when connected to KoolProg through KoolKey.
