24h/day
(Not recommended)
Regardless of the time programs, the temperature of
the domestic hot water is continuously maintained at
the DHW nominal setpoint temperature.
Example:
Heating circuit time programs
(Not recommended)
Depending on the heating circuit time programs,
the DHW setpoint is changed between the DHW
temperature nominal setpoint and the DHW
Example:
Time program 4 / DHW
(Recommended)
Time program 4 of the local controller is taken into
account for the DHW mode. The changeover
between DHW nominal setpoint and DHW reduced
