6.11. - Sensor calibration
Caution
Caution
Settings sind nur in Sonderfällen bei Erstinbetriebnahme durch den Fachmann nötig.
Falsche Messwerte können zu Fehlfunktionen führen.
Starting the commissioning help guides you in the correct order through the basic settings necessary for
commissioning, 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 to the selection mode, thus
cancelling the commissioning help.
6.12. - Commissioning
May only be started by a specialist during commissioning! Observe the explanations for
the the individual parameters in these instructions, and check whether further settings are
necessary for your application.
Deviations in the temperature values displayed, for example due to cables which are to long or sensors
which are not positioned optimally, can be compensated for manually here. The settings can be made for
each individual sensor in steps of 0.8°C (temperature) resp. 0.2% of the measuring range of the VFS / RPS
sensor (fl ow rate / pressure) per step.
Offset Sensor Settings range: -100 ... +100 / Default setting: 0
Caution
All of the settings that have been made can be reset, thus returning the controller to its delivery state.
6.13. - Factory settings
The entire parametrisation, analyses, etc. of the controller will be lost irrevocably. The
controller must then be commissioned once again.
Special functions
With some solar systems, especially with vacuum tube collectors, it may occur that the measurement value
acquisition at the collector sensor occurs too slowly or too inaccurately because the sensor is often not at
the hottest location. When the start help is activated the following sequence is carried out:
If the temperature at the collector sensor increases by the value specifi ed under “Increase” within one
minute, then the solar pump is switched on for the set “Purging time” so that the medium to be measured
can be moved to the collector sensor. If this still does not result in a normal switch-on condition, then the
start help function is subject to a 5-minute lockout time.
Start help setting range: on, off/default setting: off
Purging time setting range: 2 ... 30 sec./default setting: 5 sec.
Increase setting range: 1°C....10°C/default setting: 3°C/min.
6.14. - Start aid function
Caution
This function should only be activated by a specialist if problems arise with acquisition of
measurement values. In particular follow the instructions from the collector manufacturer.
