Setting range
Correction of displayed measured
temperature for sensor T4.
Correction of displayed measured
temperature for sensor T5.
Correction of displayed measured
temperature for sensor T6.
Setting range
When the temperature in the storage
tank is higher than the set point
temperature plus hysteresis (P1.10),
heating with the collectors stops. If
then the collector temperature exceeds
maximum temperature (P2.2), the solar
pump switches on again until collectors
are cooled down to the maximum
temperature (P2.2) plus hysteresis
(P1.18).
In case the storage tank exceeds the
maximum temperature (P2.4), the solar
pump stops unconditionally.
Special algorithm activates the solar
pump to switch -on for short intervals.
This way you get realistic temperature
of collectors. This function is used
especially with vacuum (tube) collec-
tors. This function is also possible with
classic collectors if the sensor is fitted
outside of the collector body.
If the temperature drops bellow the
set point value (P2.18), the solar pump
switches -on to prevent freezing in the
collectors and pipelines.
NOTE: This setting is suitable only for
climates areas where the temperature
only occasionally drops bellow the
freezing point.
