Set the solar pump pulse programme for solar circuit PRIO 2.
Only for solar circuit PRIO 2 it is necessary to set the solar pump pulse programme.
After the scavenging period of solar circuit PRIO 2 follows the scavenging interval
of both solar circuits.
After the scavenging interval follows the scavenging time.
During the scavenging time the solar circuit checks, if there is a new demand for
PRIO 1 or not.
If there is a demand for solar circuit 1, the pump runs, if not the scavenging period of
solar circuit 2 starts.
If during the scavenging period of solar circuit 2 there is a demand from solar circuit
1, it will be immediately fulfilled.
Note:
PRIO Runtime , PRIO break time and PRIO scavenging time are only adjustable
if
PRIO Mode
is set to
Off
.
This setting only appears with two solar circuits with two pumps.
The procedure is the same as with one pump. Additionally both pumps can run in
parallel. If the temperature difference between collector and TPU lower sensor from
the solar circuit with PRIO A is higher than the temperature difference, both solar
circuits run parallel. The parameter value is only in solar circuits with PRIO A visible
and adjustable.
