• If the temperature in the DHW cylinder is less than the required DHW
temperature by the set switch-on temperature differential, the DHW
cylinder is heated up.
Basic primary store system for heating a buffer cylinder for heat
interface units
• If the temperature in the buffer cylinder is less than required in the set
switch-on temperature differential, the buffer cylinder will be heated
up.
• Therm.dis./daily ht cyl1 must be deactivated.
This system is only available with the CR 400/CW 400/CW 800/RC300/
RC310 user interface and is configured via the DHW settings. A DHW
circulation pump can be connected.
