Program a domestic hot water pump schedule to
determine when to turn ON and OFF the pump.

is instantly available at the tap. To save energy, only turn ON
the pump during periods of the day when instant hot water
is necessary.

3.5.4 Sch reheat mode
In sch 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 tank temperature – hysteresis value; example: 35°C), the DHW tank
heats up until it reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.
