Locked
The heat source is locked as soon as the temperature at both buffer storage tank
sensors drops by less than "Temp diff buffer/HC" below the required flow temperature.

temperature request can be compensated.
Stratification protection
Line no. Operating line
4739 Stratification protection
Off ¦ Always
The buffer storage tank’s stratification protection function provides for hydraulic
balancing between the consumers and the heat source without the need for additional
shutoff valves for the buffer storage tank.
When the function is active, the volume of water on the consumer side is adjusted so
that, where possible, the addition of colder water from the buffer storage tank is
avoided.
Off:
Operation lock is deactivated.

Always:
Stratification protection is active when the heat
source is on.
For the function, a common flo
w sensor B10 must be
connected.
Overtemperature protection
Line no. Operating line
4750 Charging temp max
Solar energy charges the buffer storage tank until the set maximum charging
temperature is reached.
The protective collector over
temperature function can reactivate the collector pump
until the maximum storage tank temperature is reached.
