suitable for integrated pressurized solar system 1 collector array – 1 storage tank – 1 pump and auxiliary heating Description:
The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (delTon)
between the collector array (T1) and the storage tank (T2) is reached.
If the temperature difference between the collector array (T1)
and storage tank (T2) drops below the switch-off temperature difference (delToff),
or the temperature of storage tank (T3) reaches the preset maximum storage temperature,
then the solar circuit pump ( R1) is switched off.
Back-up heating by auxiliary boiler Within the preset time section of back-up heating,
if the temperature T3 is below the switch-on temperature,
then the circulation pump ( H1) of back-up heating is triggered,
when T3 is heated to the switch-off temperature, circulation pump H1 of back-up heating is ceased.
