NOTE
The switch-on time must always be before the switch-off time. There-
fore, when the switch-on value is being adjusted, the switch-off value
will also be changed to a later time if necessary. Adjusting the switch-off
value to a time before the switch-on value is blocked.
7.3.12 Stagnation reduction function
This function delays the end of the storage tank's loading phase in
order to reduce, or even to avoid, the system's stagnation times at high
temperatures. This causes the pump to be stopped repeatedly, and only
briefly switched on again when high collector temperatures arise. With
higher collector temperatures, the efficiency decreases significantly, thus
loading takes longer. This delays the beginning of any stagnation time.
Stagnation reduction can only be activated or deactivated.
NOTE
It is possible that this causes the storage tank to be loaded with a higher
solar temperature. However, the set maximum storage tank temperature
always has priority. This continues to be observed, as do other safety
limits.
