The REG System is also able to manage the following configuration with two tanks in series:
Il carico e le sicurezze del primo bollitore (quello principale sulla destra) seguono quanto indicato in SOLARE TERMICO CON ACCUMULO.
Se il carico di acqua calda nel Bollitore principale è terminato ed è stato selezionato Solare con Accumulo Principale e Secondario il sistema REG:
commuta la posizione della valvola presente a monte della pompa (vedi schema);
controlla la soglia di P05: Temperatura massima dell'accumulo solare ausiliario e, nel caso in cui la temperatura rilevata fosse più bassa, attiva la pompa fino al suo raggiungimento.
The load and the safeties of the first boiler (the main one on the right) follows as indicated in SOLAR THERMAL PANELS WITH ONE TANK.
If the hot water load in the main boiler is finished and Solar with Main Tank and Auxiliary Tank has been selected, the REG System:
Switches the position of the valve upstream of the pump (see diagram);
Check the P05 Auxiliary solar tank maximum Temp and, if the detected temperature is lower, it actives the pump until it is reached.

For the correct operation of this logic, it is mandatory to also have the TS5 probe in the auxiliary tank.
AVAILABLE OUTPUTS
3 digital outputs are available for the Solar Panels with two tanks:
98. Solar.Function./Special 1 which is activated when the solar pump is ON (in previous versions 4.32 of the RegConfig firmware it was called 98. Solar Pump)
102. Solar.Funct./Special 3 which is activated when the three-way valve is ON on the main tank (in previous versions 4.32 of the RegConfig firmware it was called 102. Tank diverting valve 1)
103. Solar.Funct./Special 4 which is activates when the three-way valve is ON on the auxiliary tank (in previous versions 4.32 of the RegConfig firmware it was called 102. Tank diverting valve 2)
PHOTO TBD
No analogue outputs are available for this function.
