9.1.2 Systems with two storages
For systems with more then one storage
(type1 and type2) the loading can be
optimized, depending on the energy supply.
Generally, storage with lower priority has
much lower temperature as the high priority
storage. Redirecting the energy to low-
priority storage will pull down the
temperature in the collector array, and thus
even the sunshine activity rises, this storage
will not reach the temperature level of the
high-priority one.
To “reinforce” the collector temperature, the
loading of the low-priority storage will be
interrupted shortly at fixed intervals. If the
loading criteria for the high priority storage
are fulfilled, then the high-priority storage is
loaded. Further conditions for the loading
pauses are: the collector temperature rises
with certain degrees during the loading of
the low-priority storage; respectively the
high-priority storage temperature sinks with
certain degrees, during this modus.
The higher priority storage can be set in the
“Basic settings” menu, point 10. Point 9
concerns the loading pause.
9.1.3 Rotating speed controller
Relevant values in menu
“Basic setting”: „Program“
--- Drehzahl min <100%
The solar pumps connected on the outputs
A1 and A2 can be simply switched on and
off by the controller, or can be driven with
specific rotating speed.
If this function is activated (min < 100%),
the pump power will be automatically
regulated by the controller, in order to keep
the storage temperature level constant. If
the storage temperature falls below the
„Storage Tdmax“, the controller will spin
down the pump power until the stop
hysteresis is reached.
9.1.4 Independent controller
The independent controller can be used for
thermostat (cooling or heating) and
temperature difference controller. These
functions can be overlaid by timeframes and
thus only active for certain periods of time.
The start and stop times can be adjusted in
the “Program” menu. A temperature sensor
(T1-T6) can be chosen freely in the „Basic
settings“ menu point 15.
In the case of temperature difference
controller, this is the sensor for the heating
source. The sensor for the heating target is
fixed (T6).
