temp. probe
S13
Short circuit - inlet temp. probe
ID7214
Min. refrigerant temp.
S07
The minimum refrigerant temperature was not reached
- anti-freeze protection in the heat exchanger
ID7215
Min. refrigerant temp.
(I/O2)
S07.2
The minimum refrigerant temperature (I/O2) was not
reached - anti-freeze protection in the heat exchanger

ID7228
Open contact - inlet
temp. probe
S13.2
Open contact - inlet temp. probe
ID7229
Short circuit - inlet
temp. probe
S13.2
Short circuit - inlet temp. probe
ID7231
Anti-freeze protection
(I/O 2)
The anti-freeze protection in the heat pump's heat
exchanger was triggered due to an inlet temperature of
less than 5 °C. After eliminating the cause of the error,
the controller must be restarted to reset the error
ID7236

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 (PA 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 mal-
function
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
