Lockouts
Lockouts
In case of a lockout, a warning sym-
bol ( ) and a flashing error code
appears on the display. The cause of
a fault should first be determined
and eliminated before the boiler is
being reset. The table below shows
all possible lockouts with indication
of possible cause.

plant frost protection, sensor value not
plausible)

(B10) (sensor missing, double configu-
red, configured on slave, ...)

fault (B3)
DHW temperature sensor/thermostat 2
fault (B31)
water pressure sensor fault (short- or
open-circuit)
LPB short-circuit or no bus power supply
LPB address collision

tion
BSB-Wire address collision
BSB radio communication fault
Data loss EEPROM
Two clock time masters
Maintenance message
SLT-temperature exceeded
open TL/SLT causes lockout
Boiler return temperature is higher than/
equal to (boiler temperature + Sd_RL_
groesser_VL - 2K)
Delta-T too high
Boiler temperature rises faster than allo-
wed in TempGradMax
Temp limiter safety shut-down
Thermostat burner door
Repetition error counter exceeded
Loss of flame in operation
Flue gas temperature ≥ 90˚ C
