7.10.3 PV Storage operation in BOOST mode
When the photovoltaic mode is set to PV STORAGE and the DHW-HP mode is set to BOOST, the
HP operates when the 0~10V input rises above the D20 (PV Min Voltage HP) and the electrical
heater operates when the 0~10V input rises above the D21 (PV Min Voltage EL) set point.
0~10V input raised in small steps until >5V, set from D20 (PV Min Voltage HP)
HP starts after 5 minutes delay, set from D22 (PV Min Time)
0~10V input raised in small steps until >8V, set from D21 (PV Min Voltage EL)
EL starts after 5 minutes delay, set from D22 (PV Min Time)
0~10V input decreased until <8V, set from D20 (PV Min Voltage HP)
EL stops after 5 minutes delay, set from D22 (PV Min Time)
0~10V input decreased until <5V, set from D20 (PV Min Voltage HP)
HP stops after 5 minutes delay, set from D22 (PV Min Time)
Note: If water set point temperature is achieved then the heat pump stops operation.
