Desig. Details
ID8142 Upper application area
(cooling)
The guaranteed application area of the external unit in cooling
mode is currently exceeded
ID8144 Target flow rate (I/O 2)
The flow rate has dropped below the set medium flow rate
ID8150 Max. defrost duration
HP1
The maximum duration for the defrost has been exceeded
ID8151 Max. defrost duration
HP2
The maximum duration for the defrost has been exceeded.
ID8223 SD card error (host)
SD card error (host): The SD card is either not inserted cor-
rectly or an error has occurred
ID8224 SD card error
SD card error (CP): The SD card is not inserted or an error has
occurred
ID8225 Dew point monitoring
CP
Dew point monitoring was activated but no control panel (with
integrated humidity and temperature probe) was assigned to
the cooling cycle to calculate the dew point
ID8226 Temp. dropped below
min. inlet temp.
Temp. dropped below min. inlet temp. (or dew point) - cooling
request is suppressed
ID8227 Hygiene function:
Setpoint not reached
The hygiene function was cancelled due to the maximum run-
time being reached before attaining the set temperature
ID8228 Coding resistor fault
A fault has occurred at the Rc terminal. Check the coding
resistor and the connection at the Rc terminal.
ID8229 2nd heat generator
active
Due to the return temperature being too low during defrosting,
the 2nd heat generator activated
