Reference parameter for different functions of storage
tank charging. If the value is exceeded at the storage
tank sensor then the reference value is met
(switchover point when charging to reference value
and target reference value for calculating the
optimised excess of the speed control when charging
to reference value).

Minimum excess that is demanded at the collector
sensor during charging. This excess always relates to
the storage tank sensor.

If the storage tank temperature minus setting value is
less than the temperature in the storage tank with the
lower priority, solar charging is enabled on this
storage tank.
Note: By setting different switch-on and switch-off
thresholds, swing operation can be optimised on
storage tanks with large volumes / temperature levels.

If the storage tank temperature plus setting value is
greater than the temperature in the other storage tank,
solar charging is blocked on this storage tank.
Note: By setting different switch-on and switch-off
thresholds, swing operation can be optimised on
storage tanks with large volumes / temperature levels.

If a high solar or daily yield is detected according to
parameter 08-070 or 08-071, the normal storage tank
reference value (08-062) is reduced by the setting value
for recharging with a conventional heat generator.

Recooling of the storage tank via the collector with
negative temperature difference if the max. temperature
on the day storage tank (08-059) and / or collector
maximum temperature (08-011) was exceeded.
0 = Off
1 = Recooling request is set if storage tank > storage
tank maximum temperature (08-059)
2 = Recooling request is set if storage tank > storage
tank maximum temperature (08-059) &
Collector > collector maximum temperature (08-011)
