5.5.2.1
Function Automatic venting
Explanation of [Automatic venting]
This function attempts to remove introduced air from
the fresh water module automatically.
If the function is activated and the controller detects air
intake, both pumps are operated at full speed for a
short period of time to remove the air from the fresh
water module. This can also take place multiple times
sequentially.
This function is activated by default. During
venting, the hot water can briefly be hotter than
the target temperature set.
The parameter can be found under:
5.5.2.2
Function Emergency operation only
with buffer pump
Explanation of the [Emergency operation only with
buffer pump] function
Emergency operation of the fresh water module can be
activated with this function if the admixing pump is
defective.
If it is activated, water heating is only provided by the
buffer pump. Without the admixing pump, calcification
protection of the heat exchangers is not guaranteed
Protracted emergency mode can therefore calcify the
heat exchanger.
The [Service] access level is required to perform
modifications.
