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 tank temperature –
hysteresis value = [60C]–[608]; example: 35°C), the DHW tank
heats up until it reaches the reheat set point ([60C]; example: 45°C).
This ensures that a minimum amount of hot water is available at all
times.
