Note
The drainback option is only available in systems with 1 store and 1 collector
field and if no cooling function is activated.
Note
If the drainback function ODB is activated, the factory settings of the
parameters DT O, DT F und DT S will be adapted to values suiting drain-
back systems:
DT O = 10 K
DT F = 4 K
DT S = 15 K
Additionally, the adjustment range and the factory setting of the collector
emergency shutdown CEM will change:
Adjustment range: 80 … 120 °C; Factory setting: 95 °C
Adjustments previously made in these channels will be overridden and have
to be entered again if the drainback option is deactivated later on.

Booster function
This function is used for additionally switching on a second pump when filling the
system. When solar loading starts, R2 is energised in parallel to R1. After the filling
time has elapsed, R2 switches off.
Note
The booster function is available in system 1 only.
Successive loading option
Successive loading means that the priority store will be loaded up to its maximum
temperature. If it is reached, the second store will be loaded. If the temperature of
the first store falls below the store set temperature, the second store will no longer
be loaded, regardless of whether the switch-on conditions of the priority store or
of the subordinate store are fulfilled or not.
If both store have been loaded to their set temperature, the same process described
above will take place until the stores heave reached their maximum temperature.
