C.4. - Installing the temperature sensors
The controller operates with Pt1000 temperature sensors which are accurate to the
degree, thus ensuring optimal control of system functions.
Position the sensor precisely in the area to be measured!
It is recommended that at least 20 cm of the sensor cable at the sensor are installed inside the
pipe insulation.
Connect the VFS sensors with the matching jacks.
Sensor cables for PT1000 can be extended to a maximum of 10m using a
cable with a cross-section of at least 0.75mm².
Caution
Caution
Caution
Sensor cables for the VFS sensor can be extended to 3m.
Make sure that there is no contact resistance!
The temperature sensor cables must be routed separately from mains voltage
cables, and must not, for example, be routed in the same cable duct!
Controller and VFS sensor have to have the same ground potential. The VFS
sensor uses a functional earth connector (PELV). The PE-connector of the
controller has to be connected to the pipe system near the sensor.

Parametrisation
F.1. - Commissioning help
The rst time the controller is turned on and after the
language and time are set, a query appears as to whether you want to parametrise the controller using the
commissioning help or not. The commissioning help
can also be terminated or called up again at any time
in the special functions menu. The commissioning
help guides you through the necessary basic settings
in the correct order, and provides brief descriptions
of each parameter in the display. Pressing the “esc”
key takes you back to the previous value so you can
look at the selected setting again or adjust it if desired. Pressing the “esc“ more than once
takes you back step by step to the selection mode, thus cancelling the commissioning help.
Finally, menu 4.2 under operating mode “Manual” should be used to test the switch outputs
with the consumers connected, and to check the sensor values for plausibility. Then switch
on automatic mode.
Observe the explanations for the the individual parameters on the
Caution
following pages, and check whether further settings are necessary
for your application.

Parametrisation
F.3. - Calibration
When the tap support is activated (during commissioning or in the menu „Circulation“), a calibration process is started after the commissioning. To ensure the correct operation, calibration is
also scheduled to start on every Sunday at 3:00 AM.
During commissioning, the calibration must not be interrupted.
If the weekly calibration process is not successful after 10 minutes, the process is cancelled
and the controller uses the former calibration values.
Calibration
During the callibration process a text is shown that the ow rate is measured and no tapping
is allowed.
After conrmation the circulation pump is switched off and the controller is waiting until the ow
rate has dropped to 0 L/min. Afterwards only the circulation pump is switched on and after another
60 seconds the ow rate is measured. The display shows a “Please wait” sign.
After another minute, the ow rate is measured again, and the two ow rates are compared.
If the results are identical (+- 1L/min), the result is saved.
If not, the process is started over until either the results match or 10 minutes have passed and
the calibration is cancelled and the former values are used.

If “Error” appears on the display instead of the measurement value,
then there may be a defective or incorrect temperature sensor.
If the cables are too long or the sensors are not placed optimally, the result may
Caution
be small deviations in the measurement values. In this case the display values
can be compensated for by making entries on the controller. Follow the instructions under 12.3.
What measurement values are displayed depends on the selected program, the
connected sensors and the specic device design.
The menu “1. Measurement values” serves to dis-
play the currently measured temperatures.
The menu is closed by pressing “esc” or selecting
“Exit measurement values”.

Settings range: On, Off / Default: On
4.4.7. - Min storage temp
Tap support is deactivated when the storage temperature drops below „Min storage temp“.
4.4.8. - Tap support calibration
If the tap support is activated in the menu “Circulation” or in the Setup
Wizard,acalibration is automatically started after the commissioning.
Calibration will be repeated once per week (sundays at 03:00 clock) when there is no
tapping activity.
During commissioning, calibration may not be cancelled.
If the weekly calibration is not completed successfully after 10 minutes , it will be cancelled automatically and the controller continues with the „old „ values .
Calibration Procedure:
During calibration, a message appears that the ow rate is detected and no tapping is
allowed in the meantime.
After conrmation, the circulation pump switches off and the controller waits until the
ow has fallen to 0L/Min. Afterwards, only the circulation pump switches on and waits
for 60 seconds. An alert in the display will ask to wait.
After 60 seconds, the current ow rate is detected and stored. Then, the controller waits
an additional 60 seconds and then compares the measured values. If the ow rates
(+- 1L / Min) do not match, the controller stores the new value and waits another 60
seconds. This is repeated until the values match, or operation is cancelled by the maximum term of 10 minutes.
Not only does the circulation pump switch on under normal conditions,
4.6. - Zone valve
This function switches a valve which passes the return ow into the lower or middle
storage zone. The difference between return ow and storage temperature has to be set
here. If the return ow temperature exceeds the storage temperature by this difference,
the return ow will pass into the middle storage zone. If no storage sensor is connected,
the storage temperature is set to 25°C.
4.12. - Comfort
If this function is activated, the heat exchanger will rinse for 5 seconds every 15 minutes,
so that hot water is available as soon as possible.

5.1. - Antilegionella
With the AL-function activated, the ECO SWIFT 3 makes it possible to heat the storage in selectable intervals, (AL interval) for the set residence time (AL resid. time), starting at the set time
(AL start time) until the temperature AL Tset is reached. The temperature measured at S5 has
a reference of AL Tset +5°. For the time the AL function is active, Tmax is set to AL Tset +10° to
prevent system shutdown due to high temperature.
Only when a temperature of at least „AL Tset“-5°C is reached at the Hot water sensor and, if
present, at the circulation sensor for the time set in „Al resid. time“, the AL function is regarded
as succeful. This is displayed as “Last AL heat.”. If AL is unsuccessful after 2 hours, the attempt
is canceled and will be started again the next day and an error message is displayed.

Caution
During the anti-Legionella function the storage tank is heated up to high temperatures
which can lead to scalding and damage to the system.
The user has to make sure that the antilegionella function was succesful at the set
intervals.
The AL function is switched off by default. A message also containing the date is shown
as soon as the AL function was completed successful. We recommend to set the „AL start
time“ in a period where little or no withdrawal of water takes place.
The user has to make sure that the storage temperature is AL Tset +5° when starting AL. When the storage sensor S3 is installed: If AL Tset+5° is not reached, the AL
function is not started.
This anti-Legionella function does not provide complete protection against Legionella,
because the controller is dependent on sufcient energy being fed in.

Protective functions
5.2. - Limescale Protection
To prevent the accumulation of limescale, the circulation pump can continue to rinse
the heat exchanger after a tapping for at least 5 seconds or for longest 30 seconds or
till the VFS sensor drops below Tset.
5.3. - Discharge Protection
If the temperature in the primary circuit is not always guaranteed to sufce, this function is used.
With this function activated:
When no storage sensor is connected:
If the setpoint temperature is not reached after 60 seconds, the currently measured temperature -3°C is used as new setpoint temperature. Once the pump in the primary circuit stops, the
setpoint temperature is raised to the set Tset again.
When the storage sensor is connected
If the temperature at the storage sensor is smaller than Tset -5°C, the target temperature is
lowered to the currently measured storage temperature -5°C.
In both cases “Circ Tmin” is lowered to the new setpoint temperature - Circ. hysteresis - 5°C,
where “Circ Tmin is not lower than 0° C and not higher than the set Circ Tmin.
5.4. - Seizing protection
If the seizing protection is activated, the controller switches the output in question and
the connected consumer on every day at 12:00 (setting “daily”) or weekly on Sundays
at 12:00 (setting “weekly”) for 5 seconds in order to prevent the pump and/or the valve
from sticking after an extended stationary period.
