leaving water temperature home pages
INFORMATION
The leaving water is the water that is sent to the heat
emitters. The desired leaving water temperature is set by
your installer in accordance with the heat emitter type.
Example: Underfloor heating is designed for lower leaving
water temperature than
convectors and/or fan coil units. You only have to adjust
leaving water temperature settings in case of problems.
For more information about the leaving water temperature, see the
user reference guide.

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 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.

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.
