7.3

Symptom: You are feeling too cold
(hot) in your living room

Possible cause

Increase (decrease) the desired
room temperature.

If the problem recurs daily, do
one of the following:

▪ Increase  (decrease)  the  room

Increase the desired leaving
water temperature in accordance
with the heat emitter type.

7.4

Symptom: The water at the tap is
too cold

Possible cause

Corrective action

You ran out of domestic hot
water because of unusual high
consumption.

If you immediately need domestic
hot water, activate the DHW tank
Powerful operation. However,
this consumes extra energy.

If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally.

If the problems recurs daily, do
one of the following:

▪ Increase 

the 

DHW 

tank

temperature preset value.

▪ Adjust 

the 

DHW 

tank

temperature 

schedule.

additionally 

heat 

up

Symptom: Heat pump failure

When  the  heat  pump  fails  to  operate,  the  backup  heater  can  serve
as  an  emergency  heater  and  either  automatically  or  non-
automatically take over the heat load.

▪ When auto emergency is set to Automatic and a heat pump failure

occurs,  the  backup  heater  will  automatically  take  over  the  heat
load and the domestic hot water production.

▪ When  auto  emergency  is  set  to  Manual  and  a  heat  pump  failure

occurs,  the  domestic  hot  water  and  space  heating  operation  will
stop and need to be recovered manually via the user interface. To
recover  operation  manually,  go  to  the  Malfunctioning  main  menu
screen,  where  the  user  interface  will  then  ask  you  to  confirm
whether the backup heater can take over the heat load or not.

When  the  heat  pump  fails, 

  or

interface.

Possible cause
