Alarm list
Acknowledging alarms
No harm in acknowledging an alarm. If the cause of the
alarm remains, the alarm recurs.
႑
When an alarm has been triggered, it can be acknow-
ledged in menu 9.7 (service menu) by switching HBS 16
off and on using the switch (SF1). Note that when the
power is switched on there is a 30 minute delay before
the heat pump restarts.
႑
When the alarm cannot be reset using the switch (SF1),
the operating mode, "Add. heat only", can be activated
to resume a normal temperature level in the house.
This is most easily carried out by holding the ”Operating
mode” button in for 7 seconds.
NOTE
Recurring alarms mean that there is a fault in the in-
stallation.
Alarm with automatic reset
Resets alarm Triggers alarm Alarm text on the dis-
play Alarm
no.
- When condenser supply is greater than 14°C
during cooling. When condenser supply (BT12) is less than 5 °C. Low condenser out 70
- When defrost has ended. If the defrost caused
the alarm (condenser supply during defrost is
approx. 10 °C).
- When condenser out is lower than 51 °C.
When condenser supply is greater than 60 C and
there are more than 120 seconds since shifting
to the climate system. High KF 71
- When the low pressure is greater than 0.83 MPa
(8.3 bar) and condenser out is greater than 14
degrees. When the low pressure is less than 0.65 MPa (6.5
bar) in cooling mode. Anti freeze HX 72
- When the outdoor temperature rises above 1
°C. When the outdoor temperature drops below 0
°C and the operating mode does not permit
heating. Freeze prot 73
- When the current output decreases. Too high current output from the house. Current limit 75
- When the fault has been corrected. Failed communication to one or more boards. Com. alarm 76
- When defrost has ended. When the temperature in the water heater is too
low (low pressure is less than 0.5 MPa, 5.0 bar)
during defrost. Defrosting interrupted 77
- When defrost has ended. Exceeded limit value Protection 78
Temperature limiter alarm
The following alarm blocks both AMS 10 and addition.
May be due to Description Alarm text on the dis-
play Alarm
no.
- The temperature limiter has tripped during
transportation Temperature limiter in the tank has tripped. TB alarm 3
- High temperature in the tank
- Blown circuit fuse (L2)
HBS 16 alarm
The following alarms block AMS 10. Addition runs at min permitted supply temperature.
May be due to Description Alarm text on the dis-
play Alarm
no.
- Blown circuit fuse (L3) No voltage to the outdoor unit from HBS 16. OU power failure 4
- Tripped miniature circuit breaker (-FA2)
- Low temperature during cooling
Too low temperature out from the condenser. Low condenser out 5
- Low flow during cooling Occurs if alarm 70 occurs 3 times within an hour.
