Note:
If the drainback option is activated, the cooling functions and the antifreeze
function will not be available. The H-DAY menu (holiday function) will also
not be available and cannot be selected by means of the micro button
.
Note:
The drainback option is only available in systems with 1 store and 1 collec-
tor eld 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 and DT S will be adapted to values suiting
drainback 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.
Note:
If the holiday function is activated, the drainback option will not be available.
Booster function
This function is used for additionally switching on a second pump when lling the
system. When solar loading starts, R2 is energised in parallel to R1. After the lling
time has elapsed, R2 switches off.
Note:
The booster function is available in systems 1, 2, 3, 8, and 9 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 rst 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 fullled 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.
