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.
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:

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.
