Press the ON/OFF button for 3 seconds to delete all the information stored in the History Menu : the card will automat-
ically exit the Service Menu, in order to confirm the operation.
Press the Info button for 10 seconds to exit the card Service Menu or exiting is automatic after 15 minutes .
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 Service Menu section.
B
This function depends on the value of parameter P15 Thermal Quantity Balance (Installer parameter, default
value equal to 0=Off) which must be set to 1 .
NON-MODULATING CIRCULATING PUMP (WITHOUT FLOWMETER)
The value of the following parameters must be correctly set:
•
P16 Solar circuit max. flow 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 FLOWMETER)
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 flowmeter *60 x (delta T:S3-S4) x 1,163 x ((100-valueP18)/100)/1000
N.B.:
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
once every 10 minutes, therefore when the power is restored and the solar circulating pump restarts, the cal-
culation can begin again without loss of data .
