95
The set value determines the tempera-
ture differential between the collector
temperature and the temperature of the
DHW cylinder at which the solar circuit
pump starts and stops.
Note
The value for "Hysteresis solar pump
ON 7A02" must be greater than the
value for "Hysteresis solar pump OFF
7A03".

7A07 Solar circuit flow rate
"Flow rate 7A07"
For adjusting the flow rate in the solar
circuit.
This value is used to calculate the solar
yield. The value for the flow rate must be
calculated from the set pump rate of the
solar circuit pump and the pressure drop
in the solar circuit.
Delivered condition 100 l/h
Setting 10 to 500 l/h
7A09 Fault message faulty circulation
"Detect faulty circulation 7A09"
To select whether the fault message for
a faulty check valve in the solar circuit
should be displayed (inverse circula-
tion).
