too cold
Possible cause Corrective action
You ran out of domestic hot
water because of unusual high

▪ 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.
