CONFIGURATION ERRORS
E101 1901 9 Conguration error Auto operation
blocked
Active when:
- DI2 and DI3 have
the same mapping
conguration.
- AI1 and AI5 have
the same mapping
conguration.
Correct application settings One or more conguration errors is blocking
operation to start. Check the other active
alarms to identify the conguration problem
E011 1901 1 No refrigerant
selected
Auto operation
blocked
O030 refrigerant set to
none
Set O030 refrigerant set to
an actual refrigerant
No refrigerant is selected, congure the correct
refrigerant. See "O030 Refrigerant"
E112 1903 12 AI5 not available on
this variant
Auto operation
blocked
Variant conict EKE 1A
has 1 temp. sensor
Change settings, so S3 and/
or S4 is not used
EKE 1A only operate with 1 temperature sensor
on AI2, please set I020 AI1 conguration = Not
used
E113 1903 13 AI3 not available on
this variant
Auto operation
blocked
Variant conict on
EKE 1A and And B
conguration problem
EKE 1C if PT1000
Set sensor for AI5 to be of
NTC 10K type
EKE 1A and EKE 1B don’t operate with 3
temperature sensors, please set I022 AI5
conguration = not used
E120 1903 4 AI1 not available on
this variant
Auto operation
blocked
Variant conict NO DI3
on EKE 1B and 1C
Set DI3 conguration to “not
used”
EKE 1B and EKE 1C only operate with 2 DI.
Please set O037 DI3 conguration = Not Used
E110 1903 10 Temp. oset is not
available on this
variant
Auto operation
blocked
Variant conict (not
possible to do temp
oset on EKE 1A)
Not set ext. ref conguration
to “v->temp” or “mA->t”
EKE 1A don’t include thermostat function.
Therefore, oset of temperature set point via
analogue signal is not possible. Don’t set O010
Ext. ref. conguration to mA->Temp or V->Temp
E111 1903 11 MODbus is not
available on this
variant
Auto operation
blocked
Variant conict (not
possible to use Modbus
on EKE 1A)
Not set ext. ref conguration
to “Modbus->temp” or
“Modbus->SH” or for valve
driver don’t set driver
reference conguration to
Modbus-> OD/steps
EKE 1A don’t include Modbus. Don’t set O010
Ext. ref. conguration to Modbus->SH or
Modbus->Temp
E104 1902 3 SH reference too
close to SH close
set point
Auto operation
blocked
SH close is used and SH
close set pint is too close
the actual reference/
reference minimum
Disable SH close or correct
the actual SH reference /
reference minimum to have
0,5K dierence to SH close
set point
SH reference can come to close to the SH close
safety functions et point, which can result in
unstable operation. Keep min. 0,5K separation
between minimum SH reference and N119 SH
close set point.
E105 1902 4 LOP set point too
close to MOP set
point
Auto operation
blocked
If MOP and LOP is used,
Mop set point - Lop set
point must > 5K
Disable MOP or LOP, or
adjust the dierence on
MOP-LOP set point >= 5K
The set point for the 2 pressure safety function
Lop and Mop is to close. Keep min. 5K
separation between N011 MOP set point and
N140 LOP set point
E129 1902 5 No sensor
congured for S4
Auto operation
blocked
Application need a
S4 signal for either
thermostat or Min
S4, but S4 signal is
congured
Disable the functions
needing S4 or congure a
S4 signal
Operation is congured to use S4 (media out)
sensor, but no S4 sensor is congured, Correct
I020 AI1 conguration or AI5 conguration and
check I042 S4 sensor conguration
E106 1902 6 No sensor
congured for S3
Auto operation
blocked
Thermostat need a S3
signal and no s3 signal is
congured
Disable the functions
needing S4 or congure a
S4 signal
Operation is congured to use S3 (media in)
sensor, but no S3 sensor is congured, Correct
I020 AI1 conguration or AI5 conguration and
check I041 S3 sensor conguration
E107 1902 7 SH min higher than
SH max
Auto operation
blocked
SH max lower than
SH low
Adjust SH max or SH low, SH
Max >=SH low
N010 SH min. is set higher than N009 SH max..
E108 1903 8 OD min higher than
OD max
Auto operation
blocked
OD max lower than
OD low
Adjust OD max or OD low,
OD Max >=OD low
I066 Minimum OD is set higher than N032
Maximum OD
E109 1903 9 No transmitter
congured for Pc
Auto operation
blocked
Application need
PC signal for
high condensing
temperature protection
Disable High condensing
temperature protection or
congure PC transmitter

but no Pc transmitter is congured. Correct I022
AI4 conguration and check I044 Pc transmitter
conguration
E125 1903 4 AI5 can’t operate
with AKS sensor
Auto operation
blocked
ON EKE 1C AI5
conguration is setup as
AKS sensor
Set AI5 conguration to the
of NTC10K typew
EKE 1C don't support AKS sensor on AI5. Please
use a temperature sensor on NTC type on AI5.
Correct, I022 AI5 conguration
