INFORMATION
When the DHW tank mode is reheat, the risk for capacity shortage and comfort
problem is significant. In case of frequent reheat operation, space heating/cooling
function is regularly interrupted.
INFORMATION
In situations when very low or no DHW consumption is anticipated, Reheat only
mode can result in colder than expected DHW temperatures. In such situations, it is
recommended to switch to one of the following modes:
▪ Schedule only
▪ Schedule + reheat
5.7.3 Scheduled mode
In scheduled mode, the DHW tank produces hot water corresponding to a
schedule. The best time to allow the tank to produce hot water is at night, because
the space heating demand is lower.
Example:

60°C
00:00 07:00
50°C
15°C
40°C
14:00 21:00

▪ Initially, the DHW tank temperature is the same as the temperature of the
domestic water entering the DHWtank (example: 15°C).
▪ At 00:00 the DHWtank 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
DHWtank 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 DHWtank temperature drops below a preset
value (=reheat tank temperature – hysteresis value; example: 35°C), the DHWtank
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.
