If a comparison of the current solar output and the
reference output produces a factor above the setting
value and if the reduced storage tank reference value
(08-062 - 08-072) is exceeded, recharging with a
conventional heat generator is blocked and only
permitted at a reduced reference value. If the factor is
10% (fixed hysteresis) below the setting value,
the normal storage tank reference value (08-062) is
reactivated except if the long-term block prevents it
(08-071).
If the reduced reference value is undershot, the
normal storage tank reference value (08-062) is
immediately reactivated. The calculated solar
nominal output is directly related and is taken into
account in this.

If the daily yield is above the setting value and if the
normal storage tank reference value (08-062) is
exceeded, recharging with a conventional heat
generator is only permitted at a reduced reference
value for 18 h (long-term block). After 18 h the
normal storage tank reference value (08-062) is
reactivated, except if there is still a high solar output
(see 08-070). If the reduced reference value is
undershot, the normal storage tank reference value
(08-062) is immediately reactivated. The calculated
solar nominal output is directly related and is taken
into account in this.

If the temperature at the storage tank sensor is less
than the active storage tank reference value - switch-
on the hysteresis (08-063) and if the temperature
difference in relation to the recharging sensor rises
above the setting value, recharging is enabled.

If the temperature at the storage tank sensor is
