6 Troubleshooting
6.1 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.
6.2 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
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.
