Press the Up/Down buttons to scroll the list of faults. To display the code just press the Enter button at the parameter.
To return to the list of faults just press the Enter button.
To return to the Service Menu just press the Info button. To exit the card Service Menu press the Info button for
10 seconds or exiting will be automatic after 15 minutes.
"re" - History reset
Press the ON/OFF button for 3 seconds to delete all information stored in the History Menu: the card automatically
exits the Service Menu, in order to confirm the operation.
To exit the card Service Menu press the Info button for 10 seconds or exiting will be automatic after 15 minutes.
Thermal quantity balance (Metering)
The controller calculates the accumulated energy only if the solar circulating pumps are working: the values are
then displayed via the BIL and BIL 2 parameters in the History menu, see Service Menu section.
ATTENTION:
This function is dependent on the Thermal quantity balance parameter P15 value (Installer
parameter, default 0=Off) which must be set to 1.
In case of self-regulating circulating pump, set the selector correctly.
Non-modulating circulating pump (without flow meter)
It is essential to correctly set the parameter values:
- P16 Solar circuit max. flow (l/min)
- P18 Antifreeze fluid protection rating (%)
- P23 Solar circulating pump operation (0=On/Off).
Accumulated energy A (kWh) =
Value P16 x 60 x (S3 – S1) x 1.163 x ((100-Value P18)/100) / 1000
Accumulated energy B (kWh) =
Value P16 x 60 x (S4 – S1) x 1.163 x ((100-Value P18)/100) / 1000
Note
The controller performs the instant calculation every second and updates the BIL and BIL 2 parameter values
every time the accumulated energy increases by 1kW.
In case of a power outage, the controller does not lose the accumulated energy count: the data is saved every
ten minutes, therefore the calculation can recommence without data loss when the power is restored and the
solar circulating pump starts again.
