3.4.2 Scheduled mode
In scheduled mode ( ), the DHW tank produces hot water
corresponding to a schedule. The best time to produce hot water is
during the night, because (possibly):
▪ Space heating demand is lower
▪ Electric tariffs are lower
Example:
t
60°C
00:00 07:00
50°C
15°C
40°C

3.4.3 Scheduled + reheat mode
In scheduled + reheat mode ( ), the domestic hot water control is
the same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (= Reheat; example: 45°C),
the DHW tank heats up until it reaches the preset value. This
ensures that a minimum amount of hot water is available at all times.
Example:
