▪ At 14:00 the DHW schedule is programmed to heat up the tank to 60°C.
▪ At 21:00 the DHW schedule is programmed to heat up the tank to 50°C. This
value is valid until 14:00 the next day.
▪ With the higher set temperature, in the afternoon and evening more hot water is
available.
▪ During the morning, you consume hot water and the storage tank temperature
decreases.
▪ When the tank temperature drops below a preset value (=set temperature –
hysteresis value; example 40°C), the tank is heated up to 50°C.
▪ During the afternoon and evening, you consume hot water again and the DHW
tank temperature decreases again.
▪ When the tank temperature drops below a preset value (=set temperature –
hysteresis value; example 50°C), the tank is heated up to 60°C.
