Default setting: No anti-legionella function (owing to risk of scalding).
If the "Days away from home" function is activated, the anti-legionella function will not
run. Once the "Days away from home" function has ended, the anti-legionella function
will run once at 00:00.
Example:
The anti-legionella function is enabled for every Tuesday at 08:00.
If the holiday programme finishes on Sunday at 24:00, the first anti-legionella function
will run on Monday at 00:00. The anti-legionella function will next run on Tuesday at
08:00.
Cylinder charging offset
The target temperature for cylinder charging is derived from the desired cylinder tem-
perature and the offset, to be set here.
Example:
Target cylinder temperature = 60 °C
Cylinder charging offset = 15 K
Set target temperature for cylinder charging = 75 °C
Charging pump overrun time
After switching off the unit at the end of cylinder charging, the cylinder charging pump
overrun time begins. During this time no heat request is sent to the heat generator. All
other functions (actuation of charging pump) continue during this time. This function
enables the high flow temperature required for cylinder charging to continue to be de-
livered to the cylinder before the heating circuits, in particular the burner circuit, are
enabled again for heating.
Parallel cylinder charging
During cylinder charging, the mixer circuits are supplied and the burner circuit pump is
switched off to prevent excessive flow temperatures in the unregulated heating circuit.
With "Parallel cylinder charging
– Off", the system operates with cylinder priority
switching. During the cylinder charging all other heat consumers are closed off.
