▪ Initially, the DHW tank temperature is the same as the temperature of the
domestic water entering the DHWtank (example: 15°C).
▪ At 00:00 the DHW tank is programmed to heat up the water to a preset value
(example: Comfort = 60°C).
▪ During the morning, you consume hot water and the DHW tank temperature
decreases.
▪ At 14:00 the DHW tank is programmed to heat up the water to a preset value
(example: Eco = 50°C). Hot water is available again.
▪ During the afternoon and evening, you consume hot water again and the
DHWtank temperature decreases again.
▪ At 00:00 the next day, the cycle repeats.
5.7.4 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; 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.
