[Fresh water module] function block
ETAtouch controller
5.6.2
Text menu - Adjustable parameters
Adjustable 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 function [Self-learning]
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 also called the "Auto Loop"
function.
This function is set to [Yes] by default. If [No] is
set, the operating times for the circulation pump
can be set manually.
Explanation [Circulation runtime]
Optional: only for circulation pump
This parameter specifies the duration for operating the
circulation pump after it has been started by the control
system. Once this time has expired, the circulation
pump is switched off for the set duration [Circulation
pause].
Example:
[Circulation runtime] = 3 minutes
[Circulation pause] = 10 minutes
If the circulation pump has been started, it is in
operation for 3 minutes and then disabled for
10 minutes. This means that it can only be requested
again by the control system after 13 minutes.
You can determine the required running time of
the circulation pump in the following way. Start
the circulation pump in the control system by means of
manual operation in the inputs and outputs menu. After
starting, measure the time until the fresh water module
warms up the return line for the circulation. This time
(e.g. 3 minutes) is required to heat the hot water pipe.
Then enter this time in parameter [Circulation runtime].
During this time measurement, no hot water may be
tapped (e.g. by sink, shower ...), because otherwise an
incorrect time is measured.
Explanation [Circulation pause]
Optional: only for circulation pump
This parameter sets the pause after a circulation pump
operation. The control system can only restart the
circulation pump after this pause/break has expired.
Example:
[Circulation runtime] = 3 minutes
[Circulation pause] = 10 minutes
If the circulation pump has been started, it is in
operation for 3 minutes and then disabled for
10 minutes. This means that it can only be requested
again by the control system after 13 minutes.
Explanation [Circulation pump delay]
Optional: only for circulation pump
If a time is set for this parameter, then the circulation
pump also starts outside the time window set. This is
useful if, for example, the time window ends at 8:00 pm
and you shower at 9:30 pm. When you then turn on the
hot water briefly, the circulation pump starts, and you
will have hot water for showering shortly afterwards.
Enter the same value for this parameter as for
parameter [Circulation runtime].
