11.7 Domestic hot water settings

The heat pump produces domestic hot water with the change-
over valve. The change-over valve turns the water flow to the
domestic hot water reservoir, in which case heat is not charged
to the property.
The domestic hot water reservoir's water temperature varies be-
tween the set points (nominal set point – switching differential
5°C).
The domestic hot water temperature is set in the
Factory setting: 55°C
The domestic hot water heating can be switched on and off by
pressing the Operation mode Off
When the domestic hot water's charging operation is active (Op-
eration mode On), the domestic hot water is heated according to
the selected set point. When the charging operation is switched
off (Operation mode Off), the domestic hot water's charging is
not on.
The manual charging of domestic hot water can be activated by
setting the Temporary setting on the user terminal or room unit
to "Recharge". This operation activates charging and charges the
domestic hot water to the set point.
