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 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.
