Thermal quantity balance (Calculation)

The Regulator performs the accumulated energy calculation only if the Solar Circulating Pump is working: the
value is then displayed through the parameter BIL in the History menu; see the Service Menu section.
ATTENTION: This function depends on the value of parameter P15 Thermal Quantity Balance (Installer para-
meter, default equal to 0=Off) which must be set to 1.
Non-modulating circulating pump (without fl owmeter)
The value of the following parameters must be correctly set:
- P16 Solar circuit max. fl ow rate (l/min)
- P18 Antifreeze liquid protection rating (%)
- P23 Solar circulating pump operation (0=On/Off).
Accumulated energy (kWh) =
Value P16 * 60 x (deltaT: S3 – S4) x 1.163 x ((100-Value P18)/100) / 1000
Modulating circulating pump (with fl owmeter)
The value of the following parameters must be correctly set:
- P18 Antifreeze liquid protection rating (%)
- P23 Solar Circulating Pump operation (1 = Modulating)
- P25 Flowmeter type selection.
Accumulated energy (kWh) =
Value measured by fl owmeter *60 x (delta T:S3-S4) x 1.163 x ((100-valueP18)/100)/1000
Note
The regulator performs the instantaneous calculation every second and updates the value of parameter BIL every
time the accumulated energy increases by 1kW.
In case of a power failure, the Regulator does not lose the accumulated energy calculation: the data is saved
every 10 minutes, therefore when the power is restored and the Solar Circulating Pump restarts, the calculation
can begin again without loss of data.
