17.9 Buffer tank*
The function buffer tank prevents an unintended heat transfer from the secondary side of the
domestic hot water module to the primary side. In this case, the circulation pump is switched off
in the circulation mode. This does not influence the operation during the
Disinfection.
If the storage tank temperature is equal or less than the cold water temperature, the activation
of the circulation pump is blocked. The blocking is revoked as soon as the storage tank
temperature is 5 K higher than the cold water temperature.
If the function is activated, the additional temperature is displayed in the buffer tank.
*Settings only visible with installer code (see chapter "User code").

17.10 - Reheating*
If the temperature in the buffer tank is not sufficiently high, a reheat request can be sent to the
boiler via a defined relay.
If the buffer tank temperature is equal or less than the hot water nominal temperature + 3 K, the
relay is switched on. The reheat request is sent to a boiler.
If the buffer tank temperature is equal or higher than the hot water nominal temperature + 8 K,
the relay is switched off. No reheating is required.
*Settings only visible with installer code (see chapter "User code").
