8 Troubleshooting
8.1 Symptom: You are feeling too cold
(hot) in your living room
Possible cause Corrective action
The desired room temperature is
too low (high). Increase (decrease) the desired
room temperature.
If the problem recurs daily, do
one of the following:
▪ Increase (decrease) the room
temperature preset value.
▪ Adjust the room temperature
schedule.
The desired room temperature
cannot be reached. Increase the desired leaving
water temperature in accordance
with the heat emitter type.
8.2 Symptom: The water at the tap is
too cold
Possible cause Corrective action
Your tank ran out of domestic hot
water because of unusual high
consumption. If you immediately need domestic
hot water, activate the DHW tank
booster mode. 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.
Example: Program to
additionally heat up the
DHW tank to a preset value
(Storage eco = lower tank
temperature) during the day.
The desired DHW tank
temperature is too low.
The instant DHW temperature is
too low. (Only applicable when
no tank is installed). Increase the instant DHW set
point temperature.
8.3 Symptom: Heat pump failure
When a heat pump failure occurs and auto emergency is not
activated, the domestic hot water and space heating operations will
stop and need to be recovered manually. The user interface will
prompt you to confirm whether the boiler can take over the entire
heat load or not. When the heat pump fails,
will appear on the
user interface.
Possible cause Corrective action
Heat pump is damaged. ▪ Press to view a description
of the problem.
▪ Press again.
▪ Select to allow the gas
boiler to take over the entire
head load.
▪ Call your local dealer to get
the heat pump fixed.
INFORMATION
When the gas boiler takes over the entire heat load, gas
consumption will be considerably higher.
