7.4. Commissioning
Starting the commissioning help guides you through the basic settings necessary for
commissioning 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" key more than once takes
you back to the selection mode, thus cancelling the commissioning help. (See also "E.2.
Commissioning help" on page 13).
May only be started by a specialist during commissioning! Observe
the explanations for the individual parameters in these instructions and
check whether further settings are necessary for your application.
Caution
7.5. Factory settings
All of the settings that have been made can be reset, thus returning the controller to its delivery
state.
The entire parametrisation, analyses etc. of the controller will be lost ir-
revocably. The controller must then be commissioned once again.
Caution
7.6. Heat quantity
A simple heat metering function for basic system control can be activated in this menu. Addi-
tional settings regarding the flow rate of the system are required. Additionally
be used to enter a correction value to compensate for the temperature difference between
flow and return temperature. Since the collector and the pool temperature are used to cal-
culate the heat quantity, deviations from the displayed temperature can occur. This devia-
tion can be corrected via Offset ΔT.
flow temp. 39 °C, displayed storage temp. 30 °C, measured return temp. 31 °C means a
setting of -20 % (Displayed
Heat quantity: on, off/Default: off
Flow rate setting: 10 - 5000 l/h/Default: 500 l/h
Offset ΔT setting: -50 % - +50 %/Default: 0 %
Heat quantity data is only an approximation for function control of the system.
When sensor 3 is connected, the heat quantity is calculated from the temperature
data of S1 and S3.
