Special functions

6.7. - Sensor calibration
menu 6.7
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 indivi-
dual 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.
Sensor Offset - Settings range: -100 ... +100 / Default setting: 0
Warning:
These settings are only necessary in special cases at the time of initial commissioning and may be
done by a specialist only. Incorrect settings may lead to an error.
6.8. - Commissioning
menu 6.8
Starting the commissioning help guides you in the correct order through the basic settings necessary for com-
missioning, 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..
Warning:
May only be started by a specialist during commissioning! Observe the explanations for
the individual parameters in these instructions, and check if further settings are necessary for your
application.
6.9. - Factory settings
menu 6.9
All of the settings that have been made can be reset, thus returning the controller to its delivery state.
Note:
The entire parameterization, analyses, etc. of the controller will be lost irrevocably. The cont-
roller must then be commissioned and set once again.
6.10. – Start aid function
menu 6.10
Start aid function
With some solar thermal 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 speci
fi
ed under “Increase” within one minu-
te, 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
Note:
This function shall be activated by an expert only, in case when problems with acquiring measured
values appear. First of all, instructions from the collector manufacturer shall be respected.
