Configuration parameter [Fresh water module] 2 pumps function block
6.5 [Fresh water module] 2 pumps
function block
Parameters to be set
Set or check the following parameters.
Detailed descriptions of the parameters are provided
below.
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.
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.
Explanation of the [Self-learning] function
With this function, the operating times of the circulation
pump of the last 2 weeks are saved. The operating
times of the current day are calculated based on this
and the circulation pump will be put into operation ac-
cordingly.
This function is set to [Yes] at the factory. When
[No] is set, the operating times for the circulation
pump can be set manually.
Explanation of [Flow rate too low]
Optional: only for circulation pump
This parameter determines whether the circulation
pump is generating sufficient flow for triggering the
flow switch of the fresh water module.
The setting [Yes] means that sufficient flow is
being generated.
[Yes] means that insufficient flow is being generated,
and the primary pump must therefore be started up as
well.
Explanation of [Circulation runtime]
Optional: Only with circulation pump
This parameter sets the duration for operation of the
circulation pump after it has been started. This period
is only valid inside the set time slot.
After the set period has expired, the circulation
pump is switched off for the configurable duration
of the [Circulation pause] parameter.
Explanation of [Circulation pause]
Optional: Only with circulation pump
This parameter sets the period (pause) after a
circulation pump operating phase. The control system
can only restart the circulation pump after this time has
elapsed. This pause is only valid inside the set time
slot.
