B alarm - Automatic resettable alarm
Explanation Heat pump action. Detects by Alarm
type
BT28 is greater than the stop
temperature (in menu A7) + 2 °C
for 60 min. in succession. All
electrical additional heat is
switched off after 45 min. in suc-
cession, after another 15 min. the
compressor can restart. If the
ambient temperature at any
point drops below the stop tem-
perature (in menu A7) + 2 °C the
counter restarts from 0. Compressor blocked.
Additional heat and stationary
functions activated.
The ambient temperature (BT28)
is less than the stop temperature
(menu A7). Coldambi-
ent tem-
perature 03
The compressor starts when (BT3)
is lower than maximum return
line - difference in menu A3. Compressor blocked.
The charge pump runs one
minute after the compressor has
stopped.
The return temperature(BT3) is
greater than maximum return
line.
Does not apply during defrosting.

Restarts when the pressure
switch is reset. Compressor blocked. HP sensor (BP1) interrupted be-
low or within 2 minutes after de-

alarm 10
Resets when the ambient temper-
ature (BT28) is less than 38 C. Compressor blocked.
Stationary relay is activated. Addi-
tional heat relay not activated.
The ambient temperature (BT28
) is greater than 40 °C. Hot ambi-
ent tem-
perature 13
Restarts when (BT12) is less than
max supply temperature and the
return temperature (BT13) is less
than max return temperature -
diff in menu A3. Compressor blocked. When the supply temperature
(BT12) is greater than max supply
line. High sup-
ply tem-
perature 14
Restarts automatically when BT14
is less than 60 °C. Compressor blocked. The hot gas temperature (BT14 )
is greater than 135 °C. Hot gas
stop 17
Repeated hot gas stop can give
constant hot gas alarm.
