ID7240 Connection to the KNX
interface
KNX
Connection to the KNX IP interface lost
ID7241 Negative temp. differ-
ential
µ
PC
The temperature difference when the heat generator is active
is implausible
ID7245 Tunnel occupied
KNX
The tunnel with the physical address (IA of the SMT) set on
the controller is already taken by another KNXnet/IP unit (e.g.:
ETS PC) or is not available on the interface
ID7246 Low pressure
µ
PC
The compressor is disabled due to a low pressure malfunction
ID7247 Device offline
µ
PC
Device offline - please check the data connection between the
controller board and the inverter
ID7248 Interface is not sup-
ported
KNX
The KNXnet/IP tunnelling protocol is not supported by the
detected KNX interface
ID7249 Incorrect interface
detected
KNX
The physical address of the detected KNXnet/IP interface is
not consistent with the parameter settings of the SMT con-
troller
ID7250 Min. medium flow rate
(I/O 2)
The medium flow rate fell below the heat pump's minimum
medium flow rate due to defrosting or in cooling mode. After
eliminating the cause of the error, the controller must be
restarted to reset the error
ID7251 Min. medium flow rate
The medium flow rate fell below the heat pump's minimum
medium flow rate due to defrosting or in cooling mode. After
eliminating the cause of the error, the indoor and outdoor units
must be restarted to reset the error
