Operating modes for water heating
The following statements refer to a request for hot water from
this CRC200. Water heating or temperature maintenance
remains active even if a request comes from a different
CRC200. The operating modes for hot water can be used
independently of the active operating mode for heating.

appears in the value display under the menu item Mode.
There is no separate time program for water heating. The

for water heating. Water heating is active for a half an hour
before, during and after each heating phase (all heating
circuits). The time program for water heating is also in
effect during manual operation of the heating system.
• Continuous water heating or temperature maintenance is
active when Mode appears in the value display under the
menu item ON.

when Mode appears in the value display under the menu
item OFF.
A detailed description of how immediate tank charging is
activated and how the hot water temperature is set can be
