12.9.3 Setting the solar limit
The solar limit temperature is the maximum water
temperature obtained in the appliance via the solar
heating system (measured by sensor T
1
).
This value can be set between 65 and 80°C. The
default value is 65°C.
If you set the solar limit higher than the set
point (11.4 "Setting the water temperature"), then the
solar pump will be started in order to heat the water
further once the set point has been reached. However,
this only makes sense if the solar heating system is
actually generating heat. This makes use of the
difference between the temperature at the top of the
solar collector (S
1
) and that in the appliance
(measured by S
2
).
Call up the menu for the solar limit as follows:
•

SOLAR LIMIT
Please refer to the table (3.4.2 "General and electrical
specifications") for the adjustment range and default
value for each appliance.
12.9.4 Setting the solar difference
The solar difference is a value that influences how the
operating cycle of the water heater proceeds. Call up
the menu as follows:
•
:
SETTINGS SOLAR
|
SOLAR DIFFERENCE
Please refer to the table (3.4.2 "General and electrical
specifications") for the regulation interval and default
value for each water heater.
12.9.5 Setting the Q/T sensor
The energy contribution of the solar heating system
can be calculated (12.9.6 "Displaying contribution")
using the Q/T sensor. This calculation is only possible
if your installation is equipped with such a Q/T sensor.
If this is the case, then you must set this value to
YES
,
otherwise
NO
. Call up the corresponding menu as
follows:
•

Q/T SENSOR
12.9.6 Displaying contribution
This option enables you to read out how much energy
the solar heating system supplies. For this data to be
displayed, the installation must be equipped with a
Q/T sensor (12.9.5 "Setting the Q/T sensor").
Three values are reported on the display:
•
ACTUAL
, actual energy: the amount of energy
currently being supplied.
•
LAST 24hr
, energy supplied over last 24 hours.
•
TOTAL
, total energy supplied since day 1.

12.9.7 Displaying temperatures
This option lets you read what the solar heating
system's sensors are recording. Three values are
reported on the display:
•
S1
, temperature in the collector.
•
S2
, temperature between the inlet and outlet of the
heat exchanger in the tank.
•
S3
, temperature at top of the storage tank.
