this mode, central heating and domestic water heating demands cannot be met.
10.3.2- Summer Mode:
In this mode, the device does not perform central heating but does domestic
water heating if there is a demand.
10.3.3- Winter Mode: In this mode, the device performs both central heating and domestic water
heating if there is a demand.
10.3.4- Domestic Water (DHW) Comfort Mode: In this mode, water in the heat exchanger is kept at
the domestic water set temperature and thus can be supplied at the desired temperature when the
domestic water is turned on. While heating the water in the heat exchanger in comfort mode, tap icon

buttons together for 5 seconds when the device is in Comfort mode.
