The Emergency operation function can be used
for ensuring the DHW supply in the case of a sensor
fault. In this case, the primary pump will be perma-
nently run at the adjustable Emergency speed. For
this function, the emergency speed must be aligned
with the resulting hot water temperature. The display
channel T -HW enables this alignment directly in the
Hot water menu, as soon as the emergency opera-
tion has been activated.
Note:
If a sensor fault that inhibits DHW heat-
No
ing has occurred, activate the emergency
12.0 %
operation in the Emergency op. channel.
- In order to ensure a quick entry to emergency oper-
ation in the case if an emergency, perform the align-
ment of the emergency speed as early as possible.
The emergency speed is also available for selection
in the R4 adjustment channel of the manual mode
menu. This way, the speed of the primary pump can
be limited for manual operation in order to ensure a
scald protection.
