Thermal quantity balance (Calculation)
The regulator performs the accumulated energy calculation only if the Solar Circulating Pumps are working: the va-
lues are then displayed through parameters BIL and BIL 2 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 A (kWh) =
Value P16 * 60 x (deltaT: S3 – S1) x 1.163 x ((100-Value P18)/100) / 1000
Accumulated energy B (kWh) =
Value P16 * 60 x (deltaT: S4 – S1) x 1.163 x ((100-Value P18)/100) / 1000
Note
The Regulator performs the instantaneous calculation every second and updates the values of parameters BIL
and BIL 2 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.
